[jboss-dev-forums] [jBPM Development] - jbpm process variable - Classcastexception/ classloader issues

Mahavir Jain [http://community.jboss.org/people/mahavirj] created the discussion "jbpm process variable - Classcastexception/ classloader issues" To view the discussion, visit: http://community.jboss.org/message/572147#572147 -------------------------------------------------------------- Hi, I am able to start a jbpm4.4 process from a servlet by passing a process variable (com.process.servicedata.Plan).  However, a decision handler later in the process gets a classcast exception when accessing this variable: java.lang.ClassCastException : com.process.servicedata.Plan cannot be cast to com.process.servicedata.Plan at com.process.activitymodel.HealthPlanDecisionHandler.decide( HealthPlanDecisionHandler.java:15) at org.jbpm.jpdl.internal.activity.DecisionHandlerActivity.execute( DecisionHandlerActivity.java:60) at org.jbpm.jpdl.internal.activity.DecisionHandlerActivity.execute( DecisionHandlerActivity.java:42) at org.jbpm.pvm.internal.model.op.ExecuteActivity.perform( ExecuteActivity.java:60) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperationSync( ExecutionImpl.java:672) at org.jbpm.pvm.internal.model.ExecutionImpl.performAtomicOperation( ExecutionImpl.java:632) at org.jbpm.pvm.internal.model.op.TransitionEndActivity.perform( TransitionEndActivity.java:56) This appears to be a classloader problem, so here are the details on my project structure: 1. process-web.war contains the servlet that starts the process. 1. process.jpdl.xml is in process.jar 2. process.jar is in WEB-INF/lib of process-web.war.  3. all the jbpm libraries (e.g. jbpm.jar) are in the WEB-INF/lib.  4. process.jpdl.xml in process.jar is deployed using an Ant script that was taken from the examples app that comes with jbpm.  5. process-web.war is deployed to jboss 5 and uses jbpm 4.4. Any clues on what am I missing?
