Step 1: Repackage a web app as EAR A Java EE application is a multimodule Maven project. At the very least you'll need to package a WAR and an EAR. To get started, I'll simply re-package the simple webapp as an EAR. Create a directory named javaee-app Copy the webapp from here to javaee-app . Rename struts1app to webapp . Create pom.xml under javaee-app :
<project> <modelVersion>4.0.0</modelVersion>... Create a directory named ear under javaee-app . Create pom.xml under ear : <project> <modelVersion>4.0.0</modelVersion>... Modify pom.xml in the webapp directory so that it looks like this: <project> <modelVersion>4.0.0</modelVersion> ... Build with " mvn package " in the javaee-app directory. You can see that ear-1.0.ear is successfully generated in javaee-app/ear/target . Maven successfully resolves dependencies between the sub-projects....

When I assemble a session bean without the proprietary deployment descriptor ( orion-ejb-jar.xml ), OC4J generates one like this (as can be seen from the OC4J management console):
<?xml version="1.0" encoding="utf-8"?>
<ori...
So I use this code to lookup the EJB:
import javax.naming.Context;
import javax.namin...
OC4J throws ClassCastException :
java.lang.ClassCastException: com.evermind[Oracle ...
The JNDI browser (OC4J container home -> Administration -> JNDI browser) shows that the name simpleEjb_SimpleBeanLocal is bound to: com.evermind.server.ejb.StatelessSessionDefaultLocalHomeImpl
Solution:
Change the local name in the OC4J generated orion-ejb-jar.xml to simpleEjb_SimpleBeanLocal2 and put it in the EJB package. Redeploy.
The JNDI browser shows that simpleEjb_SimpleBeanLocal is still bound to com.evermind.server.ejb.StatelessSessionDefaultLocalHomeImpl . But simpleEjb_SimpleBeanLocal2 is bound to the right proxy: SimpleBean_LocalProxy_5f4b5e5 .

Oracle's documentation on how to set up Ant tasks for web services is ambiguous and tedious. Here's a simple Ant file to accomplish that task.

First create a resource provider for Oracle AQ in orion-application.xml:
<?xml version = '1.0' encoding = 'windows-1252...
Then, hook up the EJB to the queue in orion-ejb-jar.xml:
<?xml version = '1.0' encoding = 'windows-1252...
Make sure the resource names ('rsname') match among the xml files.
Full information is available from the Oracle document titled "Oracle Containers for J2EE Enterprise JavaBeans Developer's Guide 10g (10.1.3.1.0)". Look at Appendix A.
