1. Re: Migration to JBoss AS
jaikiran Oct 25, 2010 7:00 AM (in response to dinsceg)There are no exact steps and it depends on the application and the resources used by the application. Typically, users start deploying their app to the server and if they run into some specific issues, they ask for help in the forums or lookup the documentation.

wolfgangknauf Oct 25, 2010 8:03 AM (in response to dinsceg)Hi,
basically, a working JavaEE application should deploy to JBoss without changes.
But: it depends on whether you use Oracle specific configurations. E.g the binding of EJBs to the Environment Naming Context (ENC) is not defined in the JavaEE standard, so here you would use container specific configuration files. I don't know how they are named for an oracle server, but for JBoss those are e.g. "jboss.xml" in the EJB jar, "jboss-web.xml" in the WAR file, and "jboss-client.xml" in application client projects. If you have something similar with "oracle" in the name, you will have to change the project.
The other common problem is that JBoss does not like apps which bundle certain JAR files (e.g. JSF implementation or Log4J or XML parsers).
The easiest way to find out is: copy your EAR file to the JBoss deploy directory and take a look at the server console. There will be exception stack traces, and they will point you to necessary changes (I hope).
If there is an error message which is not clear to you, feel free to ask here.
Best regards
Wolfgang
