Problem deploying EJB on JBoss 5... works fine on JBoss 4

[bigmikeatl]

I am attempting to migrate an app from JBoss 4.2.3 to JBoss 5.1 though the deployment fails with the following messages:

12:57:28,982 WARN [ClassLoaderManager] Unexpected error during load of:com.report.message.ejb.reportgenerator.ReportGeneratorListenerBean java.lang.UnsupportedClassVersionError: Bad version number in .class file

12:57:29,107 WARN [verifier] EJB spec violation: Bean : com.report.message.ejb.reportgenerator.ReportGeneratorListenerBean

Section: 22.2 Warning: The Bean Provider must specify the fully-qualified name of the Java cla ss that implements the enterprise bean's business methods in the ele ment.

Everything works perfectly if I compile with JDK 1.4.2 and deploy on JBoss 4.2.3 with JRE 1.5. I suspect something has changed with JBoss 5, but no amount of Googling has lead me to a fix.

Can someone do me a huge favor and point me in the right direction?

Thanks!

The first error means that you are running with an older JDK than what you compiled with. Based on the error messages, I suspect your EJBs were compiled with JDK 6 but are running on JDK 5. Let's take care of that first and see if the second warning goes away.

I had my JAVA_HOME set for my command prompt, but the app was reading it from the one set for the OS.  Once I changed it at the OS level, recompiled, and re-deployed, the error no longer occurs.

Thanks!
