Running a business process that contains correlation set.

A correlation set [...]

Another exception with correlation sets. This exception comes if initiation property of correlation set is set to No. The exception stacktrace is

java.lang.NoSuchMethodError “main”. This was the exception one of colleague got when he tried to run a simple java application from within Eclipse. The java file that we were trying to execute had a main method and its syntax also matches with what Java wants.
