java.lang.ClassCastException: $Proxy67 cannot be cast to or

[ajanz]

i am trying to execute a command.

source code is

 Object returnValue;
 try {
 GetProcessDefinitionsCommand cmd = new GetProcessDefinitionsCommand();
 InitialContext initialContext = new InitialContext();
 Object obj = initialContext
 .lookup("ejb/CommandServiceBean");
 System.out.println("Class:" + obj.getClass().getName());
 LocalCommandServiceHome localCommandServiceHome = (LocalCommandServiceHome) initialContext
 .lookup("ejb/CommandServiceBean");
 LocalCommandService localCommandService = localCommandServiceHome.create();
 returnValue = localCommandService.execute(cmd);
 localCommandService.remove();
 } catch (Exception e) {
 e.printStackTrace();
 throw new RuntimeException("couldn't execute command", e);
 }

but i got an

java.lang.ClassCastException: $Proxy67 cannot be cast to org.jbpm.ejb.LocalCommandServiceHome

error when executing.

i searched everywhere for a duplciate commandservicebean class but can't find it.

jbpm and my application runs under the same jvm.

please help

I have the same problem.. here is the solution (in a EJB3 context):

@EJB(mappedName="ejb/CommandServiceBean") RemoteCommandServiceHome cmdService;

and then.. (because is a EJB 2.1 for backward compatibility) you must use it like this:

result=(ProcessInstance)cmdService.create().execute(cmd);

note the create() method

problem was wrong jbossall-client.jar

after replacing it with one of jboss 4.2.2 everythins works fine...
