1. thanks for the answer
2. i wrote a hook function :
| protected void hookFunc()
| {
| logger.debug("hookFunc::Start");
| conf = JbpmConfiguration.getInstance();
| context = conf.createJbpmContext();
| graphSession = context.getGraphSession();
| //context.close();
| logger.debug("hookFunc::End");
| }
|
it run ok , but both option : with context.close() or without it
resulted in an error when i tried to run continue or start a process .
without the close it gives this error :
