WebObjects/Web Applications/Development/J2EE Integration
Thomas Pelaia 
I wouldn't consider myself a WAR expert, but I do deploy my WebObjects application using JBoss and it works very well.
Have you tried a "Hello World" type example application? If you can get a simple application running under JBoss then you should be okay with a more complicated one. I suggest starting with "Hello World" and then adding a simple EOF and that should cover everything.
There were a few tricky configurations in the initial setup. To be clear, I am using XCode, but it probably doesn't matter. Here are a few things to check.
Check you jboss-web.xml file. You definitely need to configure this file properly if you are using EOF. The application will never get started properly without this file configured correctly.
Make sure your deployment license gets built into the WAR file for deployment by setting the SERVLET_DEPLOY_LICENSE item.
Make sure the servlet project settings are correct:
- SERVLET_SINGLE_DIR_DEPLOY = NO
- SERVLET_TRUE_WAR = YES
- SERVLET_WEBAPPS_DIR = /Library/JBoss/3.2/deploy
Also, I explicitly defined a package for all of my classes. This prevents JBoss from complaining upon startup, however, JBoss still ran the application just fine anyway.
