Multiple Concurrent Peppol Senders

[simon-temple]

The tests in https://github.com/phax/phase4/tree/master/phase4-peppol-client/src/test/java/com/helger/phase4/peppol show example senders that start with:

public static void main (final String [] args)
  {
    // Provide context
    WebScopeManager.onGlobalBegin (MockServletContext.create ());

If I add the WebScopeManager call to my DocumentSender class and I have two threads instantiate and use it at the same time I get an exception:

java.lang.IllegalStateException: Another global scope with ID 'd35e000877a711edba4d0242ac1e0003' is already present. New global scope with ID 'd3acbc4977a711edba4d0242ac1e0003' is not set!

 at com.helger.web.scope.mgr.WebScopeManager.onGlobalBegin(WebScopeManager.java:140)

How should I arrange my classes and use of WebScopeManager to allow concurrent peppol sending? I'm guessing I might need to bind a scope to a thread/runner?

@simon-temple please make sure the WebScopeManager.onGlobalBegin (MockServletContext.create ()); (and the respective shutdown call) is only calles once per Java application.

So if you run the sender in multiple threads, see for example this code snippet as an example:
https://github.com/phax/phase4/blob/master/phase4-peppol-client/src/test/java/com/helger/phase4/peppol/receivers/MainSendInParallelHelger.java
It refers to MainPhase4PeppolSenderHelger.send for the main action.

@phax Thank you for the prompt response to my question :-)
