bad version in class file

Question

When I use certain jars in one of the connector projects i write for lombardi in TeamWorks eclipse i get a bad class version exception...

any ideas how this might be

Answer 1

This is a result of running code compiled with a compiler version that is greater than the version of java you are using to run it. IE Code compiled with 1.6 and you are running it with 1.5. See this post to determine what version it was compiled with.

the easiest fix is to run it with the most recent JVM.
