Hi,

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

----------- starting 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();
       }
----------- ending code -----------------

But the following exception 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

....

Excuse me, but 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.
