org.hibernate.TransientObjectException
Hello!
I've a problem and I don't know how to solucionate. I've implemented a web service whose code is:
@WebMethod
@WebResult(targetNamespace = "next")
public boolean next(@WebParam(name = "id_instance")Long id_instance)throws RemoteException{
try {
ProcessInstance instance=getJbpmContext().loadProcessInstanceForUpdate(id_instance);
if(!instance.hasEnded()){
Token token=new Token(instance);
token.signal();
jbpmContext.save(instance);
jbpmContext.save(token);
}
}catch (Exception e) {
System.out.println("Error invoking next WS");
return false;
}finally{
jbpmContext.close();
}
System.out.println("Executed WS next");
return true;
}
This method only advance a step in my jbpm process definition, but when I do jbpmContext.close(), this exception it is thrown:

Could somebody explain why and how I could fix it?
Thans in advance
