[jboss-user] [JBoss jBPM] - How to save process instance into database?

[slacker27]

the next is my code :

private void execute() throws Exception {
		
		JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
		JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
		GraphSession graphSession = jbpmContext.getGraphSession();
		TaskMgmtSession taskMgmtSession = jbpmContext.getTaskMgmtSession();

        long processDefinitionId = 1;
        org.jbpm.graph.def.ProcessDefinition processDefinition = graphSession.loadProcessDefinition(processDefinitionId);
        ProcessInstance processInstance = new ProcessInstance(processDefinition);
        org.jbpm.taskmgmt.exe.TaskInstance taskInstance = processInstance.getTaskMgmtInstance().createStartTaskInstance();
        
        processInstance.signal();
        
        jbpmContext.save(processInstance);
        
        System.out.println(jbpmContext.getSession().isOpen());
        
        Token token = processInstance.getRootToken();
		System.out.println("LAST NODE:" + token.getNode().getName());
        		
}

after i execute it, i found the process instance data has not been saved in db(mysql),
And I know if i call "jbpmContext.close()" explicitly, it was saved.
Has there any other ways to do that? 
(for example: by modifing the configuration file and do not midifing the code)


And when i config my :jbpm.cfg.xml" followed the direction in chapter 7 in the user's guide like this:










exception thrown:
Exception in thread "main" org.jbpm.JbpmException: couldn't parse jbpm configuration from resource 'jbpm.cfg.xml'
	at org.jbpm.JbpmConfiguration.getInstance(JbpmConfiguration.java:284)
	at org.jbpm.JbpmConfiguration.getInstance(JbpmConfiguration.java:256)
	at Test.execute(Test.java:30)
	at Test.main(Test.java:23)
	
	
Why?

	
Thanks!
