But when I run the application I am getting the following exception: Exception in thread "main" java.lang.NullPointerException at org.jbpm.jpdl.internal.activity.RulesActivity.execute( RulesActivity.java:51) at org.jbpm.pvm.internal.model.op.ExecuteActivity.perform( ExecuteActivity.java:60) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperationSync( ExecutionImpl.java:656) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperation( ExecutionImpl.java:616) at org.jbpm.pvm.internal.model.ExecutionImpl.start( ExecutionImpl.java:217) at org.jbpm.pvm.internal.cmd.StartProcessInstanceCmd.execute( StartProcessInstanceCmd.java:61) at org.jbpm.pvm.internal.cmd.StartProcessInstanceCmd.execute( StartProcessInstanceCmd.java:37) at org.jbpm.pvm.internal.svc.DefaultCommandService.execute( DefaultCommandService.java:42) at org.jbpm.pvm.internal.tx.StandardTransactionInterceptor.execute( StandardTransactionInterceptor.java:54) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.executeInNewEnvironment( EnvironmentInterceptor.java:53) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute( EnvironmentInterceptor.java:40) at org.jbpm.pvm.internal.svc.RetryInterceptor.execute( RetryInterceptor.java:55) at org.jbpm.pvm.internal.svc.SkipInterceptor.execute( SkipInterceptor.java:43) at org.jbpm.pvm.internal.svc.ExecutionServiceImpl.startProcessInstanceById( ExecutionServiceImpl.java:58) at com.felix.poc.MainDriver.main( MainDriver.java:40) Can anybody please tell me what can be the reason for this exception?
