Concerning MapServer config files there is a lot of grunt work necessary to configure a new set of data using an existing map design. The map file is just one part of the configuration. One needs to set up query templates and initialization files. The majority of this work can be done by using some simple tools for reading shape files.

find /cygdrive/c/GIS/MarionCoIL -name "*shp" > shapefiles.txt

This find command gives us a list of all shape files in a given directory. We want to find all the attributes for each shape file so we use the ogrinfo command.

ogrinfo -summary C:\GIS\MarionCoIL\GISData\ALI Census > Census.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\ALI Tiger > Tiger.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\Delivery Streets_Geo > Streets_Geo.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\Delivery Streets_Proj > Streets_Proj.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E Airports > Airports.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E centraliadissolve > centraliadissolve.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E clippedstreets > clippedstreets.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E Hydrology > Hydrology.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E JeffersonCounty > JeffersonCounty.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E landmarks > landmarks.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E Rail > Rail.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E tgr17121cty00 > tgr17121cty00.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E tgr17121plc00 > tgr17121plc00.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E TigerRoads > TigerRoads.txt
ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E WashingtonCounty > WashingtonCounty.txt
ogrinfo -summary ogrinfo -summary C:\GIS\MarionCoIL\GISData\NAD83E Water > Water.txt

The above script will write a file for each shapefile containing the attributes. The following is an example of the output.

We are only interested in the end of the file so we use grep with a regular expression to get only the lines containing attribute names.

grep -e ": [Integer\|String\|Real].*([0-9]*\.[0-9]*)" Hydrology.txt

This results in the following output.

Entrepreneurs

One way to make a living in Open Source is to create a proprietory format based on Open standards with proprietory extensions. Here is an example. You modify and build a custom portal from an Open Source portal. Your tool creates JSR-168 or JSR-286 war files (open standard) with proprietory extensions. Give it a .portal file suffix. The majority of the format respects the portlet standard and the extensions make it proprietory. With some modifications from a professional it can become standard therefore interesting to the Free Software Community.

I am working on a funded project for government emergency response management in the united states. There is an early open source version of this, http://www.mapimage.com/openaddress.org/. It is derived from MapServer and MapTools software.

I have contributed a MapServer integration project to the Apache Portals project. The source code is here, http://svn.apache.org/repos/asf/portals/bridges/trunk/mapserver. The documentation is here, http://wiki.apache.org/portals/MapServerPortlet.

I studied general geology and computer science leading me to a career as a independent consultant. My products include portals, internet mapping apps, xml utilities, database tools, development and compile platforms derived primarily from Apache projects.

The Java platform is my preferred development environment although I am also a competent database and Linux system administrator. I have been programming in Java for 8 years and have been working with open source software for 5 years.

Marvellous discovery. The GPX format. An xml schema for GPS data. I just used it with my GPS. A garmin legend c. To sample this out I used Debian 3.1 and an excellent tool called gpsbabel version 1.3.2. It worked right out of the box.

sudo apt-get install gpsbabel

sudo gpsbabel -t -r -w -i garmin -f usb: -o gpx -F gironde.gpx

The format stores way points with latitude longitude name description current time symbols and elevation.

Tracks are stored as track segments with track points containing the latitude longitude time and elevation.

Geospatial data units, commonly refered to as features, can be related to one another in one of three fundamental ways. Mutually exclusive meaning that there is no space common to both features, partially inclusive meaning that each feature overlaps the other but not entirely. They occupy space that is both common and unique to one another. And all inclusive meaning one feature si defined entirely within the bounds of the other. Points, lines and polygons can relate to polygons in this way. Yet lines can only intersect one another. Points can be part of a line and can be included in a polygon or be part of the polygons bound definition.

I've been doing alot of security lately and I need to backup some derby databases from one machine to another. The backup strategy is simple create an compressed archive and copy it using a secure connection to another machine. I'm documenting the process here. I want to backup a directory found at /path/parent/data. And I want the archive to maintain the directory data so that when it is expanded it writes one directory data and all the contents below it.

cd /path/parent
tar czf /tmp/data-`date +%j`.tar.gz data

The archive name is created with a %j indicating the day of the year. Therefore maintaining a year of backups. The next year will start to overwrite previous backups.

Then we want to copy the data to a remote machine. A secure encrypted copy can be sent to the remote machine. But in order to incorporate this in a cron job the remote machine must accept a password-less connection. These are the steps to generate the key. Run ssh-keygen without providing a passphrase.

ssh-keygen -t rsa
scp ~/.ssh/id_rsa.pub remoteuser@remotemachine:.ssh/authorized_keys2

Now remote connections can be made without providing a password. Meaning the remote machine trusts the local machine.

MapServer - ODBC - OGR - Postgresql 7.4.7

I'll have to admit that this is not cutting edge mapping, but it is platform independent using php4, unixodbc, and apache. It works on Linux and works on Windows. The objective here is to get map plotting working. Scalability and security are assured by using a relational database.

OGR

OGR is a vendor independent geospatial data access library included with gdal.

Simplify Data

To illustrate properly map plotting of point data such as addresses we have set up a database table containing longitude and latitude data.

Map Server

Map Server is configured to read from the database and display custom icons for point data.

OGR Configuration

ODBC:postgres/password@pg

MappingPlot

wkbPoint

MapFile Configuration

The following configuration lets the user plot different icons given the value of icon_id. The layer will only display icons from the mapping_plot table where parameters_id is equal to 1. This is achieved using the FILTERITEM and FILTER keywords. Labels are shown from the tables remarks column.

LAYER

I am trademarking right now YouML! The idea is to create a yahoo google interface implemented in j2. Features are building applications from any ML.

Sqeezing Andromda 3 into Jetspeed 2 will help this effort.

What is a MDA?

An engine that enterprets the Universal Modeling Language (UML) and exposes a java datamodel to meta facades and templates.

What are meta facades?

Objects generated from a UML model describing a framework such as struts, ojb, jsf portlet, xml schema with xmlbeans, data backup and restore with ddlutils, etc. The meta facades describe aspects of the framework such as it's capabilities to display complex web interfaces.

This is one of the grey areas of Andromda. The default Cartriges don't generate jsf or struts only. But rather an Andromda developers framework or best practice for using such technologies. Anyway what's interesting is that the framework is yours to choose. But the reality is you have to write or modify Cartriges to achieve your MDA generated framework.

What is an object model?

An object model is a java model view to the framework.

What is an Repository?

The Repository is the underlying UML implementation. Eclipse Modeling Framework and Netbeans UML implementation are two examples of Repositories.

Getting familiar?

So the contents of the repository is the bizness inteligence, or process modeled in UML.

What is all this about?

It's about working fast! No, that's not true!

It's about thinking graphically. Developing in a graphic environment. Building bug free boiler plate code. You code the logic if you want. Configuration is achieved in the meta facades and object models. The user works with UML objects by assigning them stereotypes and tagged values which determine the framework implementation. That's enough for now. Try it www.andromda.org

Profiling, profiling, profiling. When a user connects to the Apache Portals Jetspeed enterprise portal the profiler will decide what he or she gets. The profiler uses rules and criteria in order to find a match based on user, group, role, language, media type, country, language.

The Profiler Valve invokes this process. First the criteria object is build defined by the keys: page, user, group, role, media-type.

There are only two default rule objects used by J2 out of the box. The StandardProfilingRule and the RoleFallbackProfilingRule. Both set up keys for the criteria stored in the database.

The database implements two tables, PROFILING_RULE and RULE_CRITERION. When applied the rules build a ProfileLocator which is used in the content negociation logic of the ProfilerValve. Implemenation to be verified.

The ProfileLocator object is like a super map full of keys and values. The key is the Criterion object. Currently reading implementation...

Administrators can see all the rules available but one has to know the keys, 'page', and 'menu' are the most common and are setup out of the box. Both users 'user' and 'jetspeed' are setup with the 'role-group' rule set to the key 'menu'. Their 'page' rules are different. 'role-fallback' and 'j2' respectfully. Their roles are set to 'user'.

The Profiler in conjunction with the Page Manager converts location keys into file system paths. Example,

path:/search/search-engine.psml:role:user:group:user:mediatype:html:language:fr

Is converted to,

WEB-INF/pages/_role/user/_group/user/_mediatype/html/_language/fr/search/search-engine.psml

A fallback mechanism is used to search for alternatives. The first file found is used to render the page,

WEB-INF/pages/_role/user/_group/user/_mediatype/html/_language/fr/search/search-engine.psmlWEB-INF/pages/_role/user/_group/user/_mediatype/html/search/search-engine.psmlWEB-INF/pages/_role/user/_group/user/search/search-engine.psmlWEB-INF/pages/_role/user/search/search-engine.psmlWEB-INF/pages/search/search-engine.psml

See the Profiler - Page Manager design documentation for a more detailed description.

What is Fallback? People say things like a Jetspeed Profile Rule fallback, meaning the rule will fallback if it does not find an exact match. This means that the rule will loop through a sequence of paths until it finds a file that meets the Criteria. See the above example.

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']

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.

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.

2006-05-22T03:32:00.000-07:00

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.

2006-04-11T13:17:00.000-07:00

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.

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.

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.

2005-12-01T05:43:00.000-08:00

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".

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.

2005-10-25T13:09:00.000-07:00

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.

2005-10-25T02:22:00.000-07:00

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.

2005-10-23T03:01:00.000-07:00

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.

2005-10-22T17:28:00.000-07:00

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.

2005-10-21T01:54:00.000-07:00

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.

2005-10-21T01:45:00.000-07:00

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.

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
commons-cli
commons-fileupload
commons-httpclient
commons-io
commons-jelly
commons-logging
commons-modeler
commons-primatives
maven
regexps
velocity

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.

axiondb
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.

geronimo-axis-builder-1.0-SNAPSHOT.jar
geronimo-client-builder-1.0-SNAPSHOT.jar
geronimo-connector-builder-1.0-SNAPSHOT.jar
geronimo-j2ee-builder-1.0-SNAPSHOT.jar
geronimo-j2ee-schema-1.0-SNAPSHOT.jar
geronimo-jetty-builder-1.0-SNAPSHOT.jar
geronimo-naming-1.0-SNAPSHOT.jar
geronimo-naming-builder-1.0-SNAPSHOT.jar
geronimo-security-builder-1.0-SNAPSHOT.jar
geronimo-service-builder-1.0-SNAPSHOT.jar
geronimo-spring-builder-1.0-SNAPSHOT.jar
geronimo-tomcat-builder-1.0-SNAPSHOT.jar
openejb-builder-1.0-SNAPSHOT.jar

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.

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.
