Hi,

I am trying to obtain a fererence to a "ProcessEngine" with the following code:

org.jbpm.api.ProcessEngine processEngine = null ;


Configuration configuration = new Configuration();
            
       // build a process engine from a configuration
       try {
          processEngine = configuration.buildProcessEngine();  /* ManejadorJBPM4.java:360 */
       }
       catch(java.lang.Exception exc) {
          exc.printStackTrace();
       }

But the following error is printed on the console: 

17:47:29,171 ERROR [STDERR] java.lang.ClassCastException: org.jbpm.pvm.internal.
processengine.ProcessEngineImpl cannot be cast to org.jbpm.pvm.internal.processe

egistroTramite.registrarTramite(RegistroTramite.java:228)
....

I don't understand why there is a "ClassCastException" due to a casting from
org.jbpm.pvm.internal.processengine.ProcessEngineImpl to the same class ??

Any help is very appreciated.
