[rules-users] error uploading jar files: please help

Fri May 28 09:29:10 EDT 2010

Looking at your stacktrace I found: "Caused by: java.lang.ClassFormatError:
Incompatible magic value 175137123 in class file com/rb/model/Contact"

Maybe the jar you are uploading was compiled using a newer jdk version that
the one used by guvnor. Can you check that?

Best,
