RAD 7, LingakeError

[Jake Powell]

Has anyone ever seen this? Or have any clue where to start on trying to work it out? I have already "cleaned" and restarted. Let me know. Thanks!

Error 500: java.lang.LinkageError:
LinkageError while defining class: com.company.report.servlet.ReportEngine2
Could not be defined due to: (com/company/report/servlet/ReportEngine2) bad major version at offset=6
This is often caused by having a class defined at multiple locations within the classloader hierarchy.
Other potential causes include compiling against an older or newer version of the class that has an incompatible method signature.

Edit: I put some line endings into your post so it wasn't a single line of 10,000 characters wide. Impossible to read that while scrolling to the right.

Well, I figured this out after 9 hours and I feel like a total idiot because I totally looked over that line. Had to change the JDK compiler to 5.0.

Now..I am having this: I think its an ez fix I just dont know what to do because I am new to RAD:

Error 404: SRVE0203E: Servlet [ReportEngine2]: com.estar.report.servlet.ReportEngine2 was found, but is missing another required class. SRVE0206E: This error typically implies that the servlet was originally compiled with classes which cannot be located by the server. SRVE0187E: Check your classpath to ensure that all classes required by the servlet are present.SRVE0210I: This problem can be debugged by recompiling the servlet using only the classes in the

Any help would be greatly appreciated, THANKS!

[Jake Powell]

Well, figured this out as well heh. Remember kids, check your server classpath!

[kr jeet]

Can you please tell me how you changed your server classpath.

[kr jeet]

I would appreciate If anyone can anwser to my question.

[Campbell Ritchie]

Welcome to the Ranch kr jeet ( ), but it is by no means reasonable to expect an answer that soon. Please look at this FAQ.

[Campbell Ritchie]

And welcome to JavaRanch too, Jake Powell

Well done sorting your problem out.
