I just downloaded Hibernate 3.1.3 binary and tried to run it on WebSphere 6.0 (JDK1.4). I assumed that Hibernate 3.1.3 was compiled with JDK1.4.2? But why am I getting a "49" (JDK1.5) major version?

Thanks.

Hibernate version: 3.1.3

I compiled the src with JDK1.4. I modified "build.bat" to:



But I'm still getting the same error:

Could sb. point out what I did wrong?

Thanks in advance.

Problem solved.

Some other people secretly put hibernate-annotation.jar in the classpath which was obviously compiled with JDK1.5 and conflicted with "SecondPass" class in the new hibernate3.jar. Removed the not needed jar and it worked.

Case closed.
