Looks like you are using JBoss5 with JDK1.3 (which comes with WebSphere). You will have to use a minimum of JDK1.4 for this version of JBoss. Have a look at JBossVsJavaJDKVersionMatrix for more details

Read your post again. You mention:

and my JAVA_HOME is pointing to the jre v5.1.2

I'm not sure that's correct. From the command prompt go to C:\Program Files\IBM\WebSphere Studio\Application Developer\v5.1.2\eclipse\jre\bin\ and run the following command:

java -version

That will show you the version of Java being used
