This is my patch for my bug.

modules/core/src/java/org/openejb/deployment/OpenEJBModuleBuilder.java
TransactionPolicyHelper transactionPolicyHelper = new TransactionPolicyHelper(ejbJar.getAssemblyDescriptor());

modules/core/src/java/org/openejb/deployment/TransactionPolicyHelper.java
public TransactionPolicyHelper(AssemblyDescriptorType assemblyDescriptor) {
if (assemblyDescriptor != null) {
processContainerTransactions(assemblyDescriptor.getContainerTransactionArray());
}
}

public TransactionPolicyHelper(ContainerTransactionType[] containerTransactions) {
processContainerTransactions(containerTransactions);
}

private void processContainerTransactions(ContainerTransactionType[] containerTransactions) {
for (int i = 0; i < containerTransactions.length; i++) {
ContainerTransactionType containerTransaction = containerTransactions[i];
String transactionAttribute = containerTransaction.getTransAttribute().getStringValue();
MethodType[] methods = containerTransaction.getMethodArray();
for (int j = 0; j < methods.length; j++) {
MethodType method = methods[j];
String ejbName = method.getEjbName().getStringValue();
MethodTransaction methodTransaction = new MethodTransaction(method, transactionAttribute);
putMethodTransaction(ejbName, methodTransaction);
}
}
}

Seems to be that this bug is due to the fact that the builder is looking for the assembly-descriptor element. This element is optional according xml schema descriptor file http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd

How does the demo application work?

Check out Cactus, Clover.

I just had the idea to write a Getting Started guide to Geronimo.

Trying this in Geronimo :

java -jar bin/server.jar org/apache/geronimo/Demo

TIP : Before building Geronimo modify the file modules/assembly/src/plan/system-plan.xml changing INFO to DEBUG. This will tell Log4j to output debug statements.
