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:
