"Bad version number" in Java SDK

[dwhytock]

Hi...I'm getting the following stacktrace with my code:

Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

Line 23 in my code is:

    ServiceArgs serviceargs = new ServiceArgs();

Using Java 6 on WinXP.

Any ideas?

The answer is, the SDK requires Java 6, while my office is still standardized on Java 5. Setting my program to run under Java 6 in Eclipse works fine.

Yes it does. And there are also core XML classes used that were only introduced in version 6.
