Steps to Reproduce



on Server startup & everytime


Root Cause



The error that we are getting is NoClassDefFoundError.

Original error message: java.lang.Exception: java.lang.NoClassDefFoundError: com.chordiant.businessServices.referenceDataCorporateBusinessClasses.ScoreModifierCriteria

Original error message: java.lang.Exception: java.lang.NoClassDefFoundError: com.chordiant.businessServices.GenRefDataCorporateBusinessClasses.RefDataAuditCriteria
 
NoClassDefFoundError in Java comes when Java Virtual Machine is not able to find a particular class at runtime which was available during compile time
 


Resolution



Custom jars need to be copied to lib-cust folder of JXRuntime for packaging the application. This ensures that in the generated EAR, we get BMT and CMT jars with updated manifest.mf
Issue was resolved after updating manifest.mf file of JXEnterpriseBeansBMT_Websphere5.jar and JXEnterpriseBeansCMT_Websphere5 .jar with Custom jar containing the required class
