[rules-users] Error in Guvnor - Incompatible magic value

I created new JAR file using my domain Objects in Eclipse(). When I upload my JAR file in Guvnor and then If I click on Save and Validate Configuration I am getting the following ERROR. ERROR [STDERR] Caused by: java.lang.ClassFormatError: Incompatible magic value 1885430635 in class file com/otx/eag/ I felt its Version incompatible so I created JAR with JDK-6.0,5.0,1.4, but it is showing same ERROR for all the versions. I can not able to create the Rules using my domain Objects. Please Help me, How to resolve this. Thanks in Advance. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Error-in-Guvnor-Incom... Sent from the Drools - User mailing list archive at Nabble.com.
