[jbpm-users] [jBPM Users] - Re: Connection time out during Configuration.setResource

[hidman78]

Thx. I was behind a proxy and it was'nt able to connect to http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd.
I don't understand why it has to, but it is working by removing it or with direct internet connexion.
 
Now I have different problems

1)
jobexecutor import in my hibernate config seems to create the following error

But as I don't use it I deleted the line (I think there is a problem behind it but I could't find it)

2) Now i'm getting a new error on : 
ProcessInstance processinstance = executionService.startProcessInstanceByKey("taskformExample");

taskformExample appear in the console and seems to be good.
stack variables :

processEngine	JbpmConfiguration  (id=77)	
  | 	authenticatedUserIdThreadLocal	ThreadLocal<T>  (id=481)	
  | 	impl	null	
  | 	isConfigured	true	
  | 	processEngineWireContext	WireContext  (id=484)	
  | 	transactionWireDefinition	WireDefinition  (id=489)	
  | 	userCommandService	null	
  | 	userProvidedEnvironmentObjectsThreadLocal	ThreadLocal<T>  (id=492)	

executionService	ExecutionServiceImpl  (id=80)	
  | 	commandService	null	

I think the problem come from commandService that is null, but I don't know why.

I didn't change the other files.
