Installing OTRS 2.0.4 trouble ticket system on Fedore Core 4!

1. Download the RPM

[nagios@nagios noc]$ wget ftp://ftp.otrs.org/pub/otrs/RPMS/redhat/8.0/otrs-2.0.4-01.i386.rpm

2. Install RPM

[nagios@nagios noc]$ sudo rpm -ihv otrs-2.0.4-01.i386.rpm
error: Failed dependencies:
fetchmail is needed by otrs-2.0.4-01.i386

Resolve fetchmail dependency

[nagios@nagios noc]$ sudo yum install fetchmail

3. Start services

[nagios@nagios noc]$ sudo /sbin/service httpd start

I had problems with Fedora Core 4 and OTRS. This post saved me. It says to change all references to Apache to Apache2 in /etc/httpd/conf.d/otrs.conf

[nagios@nagios noc]$ sudo /sbin/service mysqld start

4. Set the password for the MySQL server

[nagios@nagios usr]$ sudo /usr/bin/mysqladmin -u root password 'new-password'
[nagios@nagios usr]$ sudo /usr/bin/mysqladmin -p -u root -h mydomain.tld password 'new-password'
Enter password:

5. Install the OTRS database

http://mydomain.tld/otrs/installer.pl

A warning message about permission write access to Config.pm was resolved by disabling SELinux with this command,

[nagios@nagios usr]$ sudo /usr/sbin/setenforce 0

6. Start OTRS service

[nagios@nagios noc]$ sudo /sbin/service otrs start

I am doing some simple :) xml editing so I thought I would explore eclipse 1.2 xml support. So here we go with the Compound XML Document Toolkit http://www.alphaworks.ibm.com/tech/cxde

I'm using windows at the moment so I'm getting the all in one starter kit from the Web Tools project http://www.eclipse.org/webtools/ which depends on GEF and EMF.

Big download...

The installation of the Compound XML Document Toolkit was not successful but after an hour or two of using Web Tools xml editor I am satisfied to say that it provides good xml, xsl, dtd, and xml schema support. On the other hand my first wish would be to have a means of displaying the xpath a specific target location to any other place in the document. Visually determining an xpath such as the following is rather cumbersome,

XMI/XMI.content/UML:Model/UML:Namespace.ownedElement/UML:Package/UML:Namespace.ownedElement/UML:UseCase/UML:Namespace.ownedElement/UML:SignalEvent/UML:Event.parameter/UML:Parameter/UML:ModelElement.taggedValue/UML:TaggedValue/UML:TaggedValue.referenceValue/UML:ModelElement/XMI.extension/referentPath[@xmi.value='org.andromda.profile::presentation::WebFieldType::selecttextinput']

Thanks for reading...Keep coming back for more on UML editing.

This blog will present you with a common method for maintaining branches of an open source project. A concrete example would be when you take and modify an opensource project. Branches are maintained with diff files. The subversion command for diff is 'svn diff myDirectory'. Suppose you want to use an open source project to create your own website. Just keep a copy of the svn diff and send that to any machine that will be used to deploy the website.

For the second time I had a problem with javac on linux. You can not use the ~ char in the -classpath flag.

You must make a choice when developing a portlet. The Simplest being the javax.portlet.GenericPortlet. Others include the FacesPortlet, ServletPortlet, StrutsPortlet, VelocityPortlet, PerlPortlet, PHPApplicationPortlet, DotNetPortlet, and the MapServerPortlet. Documented on the Apache Portals Bridges project website.

I wrote the Jetspeed 2.0 release announcement. Here are some additional features of Jetspeed.

Standard and secure platform for creating custom web portals.

Jetspeed Security and Content Management

The objective of this text is to outline how to provide portal content and functionality to an outside server. There are two issues. One is the user must be authenticated to use a particular content. The other is defining the method to access the pages without the menu and logos. A third issue comes to mind if the provided content is inline rather than in an iframe (the server does all of the content negociation and the clients browser does not even know that it is getting content from a third party) which is all urls for images, links, forms, and resources must be standardized so that the server can know when it is to act as a proxy to third party portal content).

Authentication

One way to do authorization is by using a post request over https where password credentials can be verified. Another way is to sacrafice security for facility by allowing get requests to be made over http. This is not desirable but may facilitate testing. Production servers must make the post over a secure connection.

Content without menus and logos

One assumption that is made is the menus and logos will be invisible and only the content of the portal will be present. For this to work we need to be able to use two different themes depending on the caller.

A page accessed using the MyPage.psml will be rendered with the logo and menus. If the same page is accessed using MyPage.psml?org.apache.portals.jetspeed.theme=simple the logos and menus would be hidden. This parameter can also be passed one time during authetication to set the theme used for the entire session.

URLs

If the server does the content negociation it will act as a proxy to the Jetspeed portal requesting content and providing it inline to the end user. All URLs with a given prefix would have to be redirected to another server for content. A portlet can be written for Jetspeed to act as a proxy server to aquire third party content.

Code

This url will authenticate the user and override all page themes so that the portal content is presented without menus and logos.

http://localhost:8080/jetspeed/login/proxy?org.apache.jetspeed.login.username=user&org.apache.jetspeed.login.password=user&org.apache.jetspeed.theme.override=simple

It depends on a patch submitted by me a few days ago. See the Jira issue

The preferences implementation in Apache Jetspeed is currently based on a database persistence model. I'm stepping through the Jetspeed startup to see where this is going. It uses Apache DB OJB to access the database. Preferences are the first objects to be initialized with database access.

Jetspeed preferences or the Portal api preferences are getting on my nerves. I am specifying preferences in the psml file. When I debug I get calls to two separate FragmentImpl.getPreferences methods.

The first is a call to the FragmentImpl in package,
org.apache.jetspeed.om.page.psml
Which is related to the portlet itself.

The second is a call to the FragmentImpl in package,
org.apache.jetspeed.om.page.impl
Which is related to layouts.

The fist call populates a o.a.j.om.preference.impl.FragmentPortletPreferenceSet from o.a.j.om.page.ContentFragmentImpl. Then pluto eats the preference and I never see it in my portlet.

Hmm, this is the second time I got this exception using Andromda. It is caused by an invalid character in my @andromda.presentation.view.field.format tagged value. Dates can not use the 'maxlength 10' value 'strict dd/MM/yyyy' is better validation rule.

Geronimo is a truly modular application server. It can be build to run any particular war or ear with only the components that it needs. If your application is not running jms then build geronimo without activemq. If it is not using ejb then build it without openejb. This allows for a leaner faster application server, customized to run only the components that are needed.

Geronimo blogging is back, Andromda, MapServer, and Jetspeed news will follow. This is a list of some important modules built during the 'maven new' compile.

Geronimo :: Common
Geronimo :: Util
Geronimo :: System

The issues http://issues.apache.org/jira/browse/JS2-395 and http://issues.apache.org/jira/browse/JS2-350 will be interesting to watch because they enable database managment of PSML files and Graffito provides a graphical CMS to PSML content.

I've been studying the data access methods used by MapServer and in theory any ODBC connection can be used to obtain data from a relational database. That's probably what we want. Afterwords all we need is a nifty car icon to indicate the direction that the car is travelling (the direction part may be tricky). MapServer uses SYMBOLS to label geo features using an icon image.

MapServer supports four categories of data access. The first is the basic file method. It can access files of type shape, arcinfo, mapinfo, us census tiger, csv, etc. These are read only methods of accessing data. Other sources could update these files and MapServer would get the updates. This wouldn't be a good idea because there could be a io conflict.

ODBC can be used to access relational databases (SQL Server, Oracle, MySQL, and company)

The third category of data access is not applicable to our work. MapServer can access data provided by a Spatial database engine like ArcSDE, Oracle Spatial, or PostGIS. These solutions provide spatial indexing and special geographic types. I think this is out of our scope. It would take longer to set up, it is more complex to install. I would suggest exploring this option if you expect to address larger clients.

The last thing that I want to tell you about is MapScript. MapServer exposes their application programing interface so that hackers and integraters can do custom things with MapServer in the language of their choice (Java,PHP,Perl,Ruby). We are not using it but It can be used to create maps and plot data, as well as query data. I will deliver you an example that I found on the net.

And lastly, I looked at your database and the GPSActive table looks like it could be plotted on the Map using the ODBC solution. There were duplicates in the table but they had the same latitude and longitude. MapServer will plot all data from the table. If we want to get fancy and label each car with their own icon we will have to read the database using PHP and plot using MapScript. Give me some more thoughts on what you need.

Here is a simple script that I found using ms4w from maptools.org. It helped me get a grasp on MapScript PHP for MapServer.

Clarify the following skin, theme, layout-decorator, portlet-decorator.

I'm thinking about Jetspeed documentation. Correct me if I'm wrong, it sucks, so what can be done about it. Here are things that can be done by Users, Developers, and Administrators.

User can CustomizeTheLayout, CustomizeTheStyle, CustomizeTemplates, CreatePages, CreateFolders, CreateSeparators, and CreateLinks.

Developers can WritePortlets, ConfigurePortlets, WriteLayouts, WriteStyles, as well as anything a user can do.

Administrators can InstallJetspeed, OptimizeJetspeed, ClusterJetspeed, CreateUsers, CreateGroups, and CreateRoles. As well as anything a user or developer can do. They are extremely lazy people who often say "That's the developers job".

[#JS2-188] Implement the LDAP - ASF JIRA summarizes the development of LDAP authentication and authorization.

Another important feature of Jetspeed is its ability to integrate with Apache Derby.

The Jetspeed issue tracker, Browse Project - ASF JIRA, provides quick access to outstanding, resolved, added, updated, and important bugs.

The most significant recently added to jetspeed are translations, portlet api compliance, statistics and page manager implementations.

A quick thing that anyone can do with Jetspeed is change the Page, Link, PageSecurity, FolderMetadata in the JS2_SOURCE/src/webapp/WEB-INF/pages/ directory.

Installing wifi card on my toshiba 1800-100 with suse 10.0 and ndiswrapper. The card is a Belkin 54g "High-Speed Mode Wireless G Notebook Network Card" model number is f5d7011. The ndiswrapper package version 1.5 requires the kernel sources and gcc which were not installed by default by suse 10.0.

Just follow the ndiswrapper guide and it should work.

A MapServer portlet requires the following elements:

• MapServer Software
• Geographic Data
• MapServer Configuration
• Apache Portlet Bridge for MapServer
  
• Jetspeed Configuration

MapServer Software
MapServer is a C program therfore you must obtain the proper version for your target operating system. Linux and Unix users will find that downloading the source and compiling it is the simplest alternative. Listed here are links to MapServer source and its required dependencies. Build each of these packages using the ./configure, make, and sudo make install commands. Building MapServer will tell you which dependencies are missing on your system.

MapServer-4.6.1 source code
GD-2.0.33 source code
Freetype-2.1.10 source code
Jpeg-6b source code
Png-1.2.8 source code

Windows users can use the ms4w package provided by maptools.org.

Mac OS users will find help here.

Geographic Data
The MapServer demo includes some sample geographic data.

MapServer Configuration
MapServer is configured using a MapFile. The demo configuration file is itasca.map.

Apache Portal Bridge for MapServer
A contribution to the Apache Portal Bridges project yeilded a component capable of executing the MapServer program. This bridge uses the portlet initalization parameters to determine the inital map. MapScript for Java is on the roadmap.

Jetspeed Configuration
A simple modification to any existing portlet.xml is enough to deploy a new MapServer map. See the attachment in the Jira issue.

I just realized the best way to trick google into better reference. That is to publish multiple formats of the same document. Word, OpenOffice, PDF, TXT, RTF. Give me credit if you use this method.

I am going to write a MapServer portlet. The mapserv cgi script can be used on the command line like this.

./mapserv QUERY_STRING="layer=Citylimits&layer=Citywards&zoomdir=1&zoomsize=2&map=%2Fms4w%2FApache%2Fhtdocs%2Fmap%2FMorganCo.map&program=%2Fcgi-bin%2Fmapserv&root=%2Fmap&map_web_imagepath=%2Ftmp%2F&map_web_imageurl=%2Fmap%2Ftmp%2F&map_web_template=map.html"

The parameter program will be replaced by a servlet mapping. Therefore all request to the url, /browse/map, will be redirected to the mapserver.

The template will have all

html

and

body

tags removed so that it is an html page fragment.

A MapServerPortlet class will implement the doView method and encapsulate the mapserv binary execution. The portlet requires the following settings, the location of the mapserv binary, the location of the map file, the initial layer to display, the template to use, the absolute uri to the servlet mapping, the temporary image directory, the temporary image uri, the zoom mode, the zoom value.

A Jetspeed bridge is required. It is based on the Perl bridge which was too busy for the mapserver needs, so I just adapted it to the simplicity of mapserver.

MapServer 4.6 requests can probably be broken down into the following steps. Here the common name is presented along with its corresponding code fragment and/or the name of the source file.

• Create a mapserver object using mapserv.c.loadParams and mapserv.c.loadMap
  
• Parse parameters mapserv.c.loadForm
  
• Determine the mode. One of three are know to me, browse,query, and nquery. This is determined by the msObj.Mode property. Most of this logic is in mapserv.c.main.

Only the Browse mode is explained here.

• Extent, scale, and query files are evaluated using mapserv.c.setExtent mapserv.c.checkWebScale and mapserv.c.msLoadQuery
• Images are generated using maptemplate.c.msGenerateImages
• Map is drawn using mapdraw.c.msDrawMap
• Map is drawn using mapdraw.c.msDrawQueryMap
• Legend is drawn using maplegend.c.msDrawLegend
• Scalebar is drawn using mapscale.c.msDrawScalebar
• Reference map is drawn using mapraster.c.msDrawReferenceMap
• 
  

NOTES : Nice things to have.

• Two maps on one page.
  

Implicit versus explicit application development. Creating a application that relies on implicit configuration or rules is a bad idea. I came across a struts configuration in Jetspeed that made me think of this subject. A $M$P pattern indicated that pages exist with the /module/path. Although this case is not an implicit declaration programming with out explicitly declaring classes, configuration, or properties will only create confusion and hard to debug applications.

Another short tutorial on the Jetspeed portlet.

CreateYourOwnSimpleServletPortal

= The portlet.xml =

Add a new portlet tag to one of the existing portlet applications. The security application is know to work.

{{{
edit $JETSPEED2_SRC/applications/security/src/webapps/WEB-INF/portlets.xml
}}}

The portlet tag can be placed anywhere inside the root element called portlet-app.

{{{


ViewPage
/WEB-INF/security/login/simple.jsp

MySimplePortlet
org.apache.portals.bridges.common.GenericServletPortlet

}}}

= The psml =

Add a fragment tag to one of the psml files. The default page is appropriate.

{{{
edit $JETSPEED2_SRC/src/webapp/WEB-INF/pages/default-page.psml
}}}

Note that the id must be unique. Using the same id twice will confuse Jetspeed. There is no error handling regarding this point so be creative.

{{{




}}}

= The JSP =

We did say that this is a simple servlet portlet, so the JSP will be simple.

{{{
edit $JETSPEED2_SRC/applications/security/src/webapps/WEB-INF/security/login/simple.jsp
}}}

Here are the contents of a very simple JSP.

{{{
<%@page import="java.util.Date"%>
The time is <%=(new Date()).toString()%>
}}}

Please read QuickstartForTheImpatient before before proceeding.

To simplify this document $JS2_PAGES will represent the directory path src/webapp/WEB-INF/pages of the Jetspeed 2 source code.

= Jetspeed Portlet Layout =

The Jetspeed portlet layout is defined by a number of mechanisms. The $JS2_PAGES file structure has an effect on the layout. Here are some modifications you can do without breaking the build.

== Change the Default Page ==
Modify the column and row indexes for some or all of the portlets on the welcome page($JS2_PAGES/default-page.psml).

== Add Additional Links ==
Create a file called myLink.link in the directory $JS2_PAGES. Refer to or copy one of the other .link files for the proper syntax.

== Create a New Tab ==
Tabs can be created by simply creating a psml file in the $JS2_PAGES directory. Copy $JS2_PAGES/default-page.psml to $JS2_PAGES/my-page.psml. Note that the security-constraint tag in psml defines the roles authorized to view this page.

== Modify the Menu ==
The left menu is defined in the folder.metadata file of each directory of the $JS2_PAGES directory.

I see that in Jetspeed's demo portlets the web.xml defines the following tags security-constraint, login-config, and multiple security-role tags. The meaning of these are explained here.

security-constraint defines a list of web resources (urls) protected by web security and a list of roles authorized to access these resources.

login-config defines the authentication method and the realm name. Optionally a login page and a error page can be defined.

The security-role tag must appear if this is a custom role that does not already exist in the container.

Seems there are some patches to do for Jetspeed.

demo/src/webapp/WEB-INF/jetspeed-portlet.xml and demo/src/webapp/WEB-INF/portlet.xml could use some more languages. Some dc:title tags with attributes xml:lang="en" to support Japanese, Chinese, Spanish, Italian as specified in the file resources.

I am writing a JetSpeed 2 quickstart development guide for the impatient.

This is completely unrelated to Geronimo but important to creative people. When creating a name use something that the reader wants. In this case it is a job, Media Job.

I am at ApacheCon Europe 2005 and the focus is on Java, Spring has been integrated in JetSpeed, ServiceMix, AndroMDA, Security, clustering, transaction managment, and POJOs. POJOs are important in web services jaxrpc which uses Java Service Enpoint JSE technology.

I just created a web page on a Wiki like travel site called World 66.

The Apache Geronimo code source can be imported into eclipse. Or, preferably, one can change the workspace to the location of the directory where subversion checked out geronimo (the directory containing the directory geronimo). Proceed with the creation of a "New Java Project" by naming the project geronimo. Eclipse then reports some 30,000 compile errors. Enabling the "assert" keyword resoves a large number of these. Remove all the libraries detected by Eclipse and proceed to add the following libraries from your maven repository. Libraries used by geronimo include,

• cglib (resolves 1% of the errors)
• mx4j and mx4j remote (resolves less than 2% of the errors)
• log4j (resolves less than 1% of the errors)
• xml-resolver (resolves less than 1% of the errors)
• junit (25% of the errors) and is only required for the tests
  

The geronimo-kernel, geronimo-system, geronimo-common and a slew of j2ee specs should now compile successfully. The j2ee specs compiled include transactions, ejb, jms, servlet, jsp, connectors, activation, deployment, authorization contract for containers, jmx, javamail, xml registries, saaj, jaxrcp, j2ee, and corba. Notice that geronimo-kernel and geronimo-deployment have circular dependency. Then add the xmlbeans library.

• xmlbeans (resolves 51% of the errors)

XMLBeans is a special case because this is required by the generated code, but is no the less required at runtime.

• concurrent (2%)
  
• exolab castor 0.9.5.3 (6%)
  
• axis 1.3 (4%)
  

Concurrent, Castor, and Axis resolve a number of build errors suggesting that each play an important role in Geronimo compilation. At this point the web service and axis modules are compiling.

• howl (%)

Howl assists in Geronimo transaction managment. The Transaction module is now compiling.

• activeio
• ant
  
• antlr
• commons-collections

These libraries result in the resolution of 6% of the compile errors.

• hsqldb

HSQLDB is required for some of the security tests. Otherwise the security module is now compiling.

• openejb
• openorb
  

These libraries support common j2ee implementations of ejb and corba.

Security is now compiling.

• axis scout
  
• bountycastle
• catalina
• derby
• jetty
• mockobjects
• objectweb asm
  
• spring
• xfire
  
• xstream
  

The frameworks that are extended by Geronimo are AxionDB, Axis Scout, BountyCastle, Catalina, Derby, Jetty, MockObjects, ObjectWeb ASM, Spring, XFire, and XStream. Adding these libraries resolves 10% of the compile errors.

These xmlbeans libraries represent configuration utilities used for reading and writing xml input and output. Adding these libraries to your Eclipse project classpath resolves 12% of the compile errors. All Geronimo modules that suffix "-builder" represent some kind of configuration processing library.

The remaining errors were caused by duplicate class files. I deleted them to move forward.

This is where it gets interesting. The server is started using the org.apache.geronimo.system.main.Daemon class in the system module. It requires the server.jar to be on the classpath. It is found in the modules/assembly/target/geronimo-1.0-SNAPSHOT/bin directory. Debugging this now. There are several errors that need to be work out.

The Eclipse UML2 Project is rapidly becoming a strong alternative to using MagicDraw for Andromda.

There are some electronic books listed on the Apache Geronimo Documentation page. Authors include Katia Aresti González, David Blevins, Aaron Mulder.

It never hurts to browse the Apache Geronimo Javadoc API.

There are five Apache Geronimo Mailing Lists, dev, user, source, pmc, and tck. The last two are reserved for people doing project managment and certification respectfully.

Who should maintain open source projects? | InfoWorld | Column | 2005-04-11 | By Neil McAllister. JBoss vs Joe. This article explains the business strategy behind two open source models. GPL vs BSD. The license is not mentioned, but ultimately it determines everything.

Overview (UML 1.4 with Diagram Interchange API) is a OMG standard.

Much of the Agentis Platform is based on open source projects. These include Ant, JBoss, CVS, CruiseControl, and NetBeans.

These are keywords that I obtained from James Odell's paper, UML 2.0 and Agents: How to Build Agent-based Systems with the new UML Standard.

Software methodology = modeling language + software process

Agent technology software system characteristics = situation awarness + intelligent behavior + distributed + mobility + nomadic users

SODA = Societies in Open Distributed Agent spaces = agent societies + agent environments + inter-agent aspects.

Agent methodology = external viewpoint (Services Purpose and Responsibitities) + internal viewpoint (Beliefs Goals and Plans).

See MESSAGE, Tropos, Prometheus, and JACK.

See section 3.1 of James Odell's paper.

MDA is the process of converting UML to an deployable application.

The UML models that are used by MDA are in two categories. Structural Diagrams = Static Aspects. Behavioral Diagrams = Dynamic Aspects.

Structural Diagrams = class + object + composition + component + deployment
Behavioral Diagrams = use case + activity + state + sequence + communication + interaction

Generating deployable applications is the final stage of MDA. It requires these models: Computational Independent Model (CIM), Platform Independent Model (PIM), and the Platform Specific Model (PSM). These are the models created during generation. See AndroMDA for more information on MDA. See Agentis for more information on Agent technology.

The FIPA Abstract Architecture for Agent technolgies is the recomended reference for the Java specification request (JSR) for Java Agent Services.

I just met James Odell and I read one of his papers on Agent technology. Some key words that apply to Agent technology are People Groups Roles Organisation Issues Events Ontology Emersion Cohesion and Coupling. UML 2.0 can be used to express Agent oriented systems using the the latest diagrams and extensions. See his most recent paper. James Odell--Publications

This series is on Agent technology, a branch of Artificial Intelligence. These are some sites I know that reference Agents : Open Directory - Computers: Artificial Intelligence: Agents, http://www.objs.com/agent/

I just read about the CMP implementation. Things to not is that cardinal relationships are supported, auto generation of primary keys, TranQL is the intermediate framework between OpenEJB and the underlying database. a connection factory is configured using the cmp-connection-factory. See Working with Enterprise JavaBeans - Geronimo Wiki

Geronimo uses the MX4J implementation of the Java Managment Extension. Here is a utility for working with GBeans, JMXUtil (Geronimo :: Kernel 1.0-SNAPSHOT API)

Geronimo has a kernel and obviously this is where it is documented, org.apache.geronimo.kernel.config (Geronimo :: Kernel 1.0-SNAPSHOT API)

org.apache.geronimo.gbean (Geronimo :: Kernel 1.0-SNAPSHOT API), the javadoc for GBeans.

Building ActiveMQ to test the peer environment from laptops producing and consuming purchase orders regardless of being connected to the Internet. JMS solution uses the peer and reliable protocol provided by ActiveMQ.

Testing requires SVN, Java, Maven, and the ActiveMQ source code. These are the quick start commands,

svn co svn://svn.activemq.org/activemq/scm/trunk/activemq
cd activemq
maven
cd modules/assembly
maven server
maven producer
maven consumer

More to come on customizing and integrating this configuration.

IconBAZAAR is classic. It is nice to see that it is still alive.

There is a JMS sample provided in the Gluecode Software | Geronimo Documentation & Samples distribution.

Deployment - Geronimo Wiki contains sample deployment commands.

Running - Geronimo Wiki lists the optional Config IDs used when starting Geronimo.

I start Geronimo using this command,

java -jar bin/server.jar org/apache/geronimo/DebugConsole org/apache/geronimo/RuntimeDeployer org/apache/geronimo/DefaultDatabase org/apache/geronimo/SystemJMS

The Debug, Deployer, JMS, and Database GBeans are started. As stated var/config/config.list contains the last stable config therefore subsequent restart is done using this command,

java -jar bin/server.jar

Geronimo EAR Deployment is done using this command,

java -jar bin/deployer.jar deploy ~/agentis/agentis/Agentis370_350IDE/work/SimpleProjectTest/dist/SimpleProjectTest-agent.ear

Be aware that the file $GERONIMO_HOME/var/config/config.list maintains the list of modules started by the Geronimo Server. By default they are org/apache/geronimo/Server and org/apache/geronimo/System. I use this the server.jar executable to add them but you can add them manually if you like.

Today Geronimo is Running. I followed the Building instructions. The debug console was deployed and executed without errors.

Open Source Software Development for Service Oriented Projects

By Philip Mark Donaghy

There is no doubt that Open Source methods are becoming the norm used by service agencies everywhere. These are the guidelines I recommend when developing using open source software. These principals will guarantee an effective development process.

Communication with Mailing Lists

A large percentage of projects fail due to poor communications. It is very important that communication is traced so that managers, developers, and clients can have the correct information at the right time.

The solution to this problem :

Use internal mailing lists to notify people of news, events and or changes that are important to the end users as well as managers, clients, and developers. Three lists should be sufficient. The client list, a developers list, and a managers list. In addition the use of public mailing lists to effectively monitor software limitations and benefits.

Modeled Architecture using UML, Object, Exchange, and Database models

Problems arise from ineffectively copying and pasting source code.

The solution to this problem :

Use models to define the architecture of the application. Model driven architecture is the most modern method of developing service oriented software. A large portion of the application can be automatically generated using Velocity or AndroMDA.

Client Workflow

A third difficulty comes from poor client specifications. The solution is to monitor the clients needs and expectations.

The solution to this problem :

Architects and developers can not effectively create service oriented applications without the technical and functional contacts with the client.

Developer Workflow

Developers are curious animals. The all have their habits and methods of contributing to a project. The most important characteristics necessary to identify a responsible developer are his or her "bonne volonté", the desire to contribute ones maximum potential toward a projects success, and his or her professional attitude. These aside, here are some simple steps all developers should follow.

• Verify the stability of the source code

• Notify project directors when source code is unstable

• Debug

• Find the person responsible for the error

• Work with them to estimate the

• Run regression tests

• Notify project directors when regression tests fail

• Debug

• Find the person responsible for the error

• Work with them to estimate the correction

• Evaluate remaining development

• Meet with project directors to discuss solutions

Language

The software documentation must use a consistent language.

The solution to this problem :

A development team often consists of many nationalities. In such a case documentation communication should be written in English.

French can be the dominant language if the clients, managers, and staff are all French nationals or master French as a second language.

Development Platforms

A final and frequent problem arises with the network services used during the development process and the cost to maintain them.

The solution to this problem :

The development platform must be composed of all elements to run the application independently of network connections. Therefore the database must be installed on the development machine. Traditional Windows machines are not practical, secure or fast enough for this scenario therefore Linux is recommended.

Source Control

Problems arise when source code is locked by other developers.

The solution to this problem :

Use the most common open source source control. At the time of this writing this is CVS, although Subversion has be recently adopted by most new and cutting edge development efforts.

Build Scripts

Problems arise when build scripts are platform dependent.

The solution to this problem :

Use the most common open source build system. At the time of this writing this is Ant, although Maven is making great strides.

As with development build scripts should modular. Meaning that one central build script calls other scripts.

Delays

Delays can be avoided only by synchronizing the efforts made by the client, managers, third parties, and developers. In order to master the planning of a project all the technical, functional, and management aspects must be mastered. At our company we strive to make this our mission. Our contracts describe the exact solution and its implementation along with the time to delivery and the cost.
