TeamConcert in headless mode with repository connection

Hi community,

I'm currently working on a plugin that fetches and processes work items. The plugin runs totally fine in normal mode but I consider to get the plugin run in headless mode. But as soon as I try to connect to my team repository, my plugin hangs up.

I'm pretty sure that I have to manually trigger the login process or other kind of required steps but I don't know which ones and I don't know how to do it. I'd like to do something like:

IProjectAreaHandle projectAreaHandle = ProjectAreas.getInstance().getByName("Jazz Project");

		

ITeamRepository teamRepository =  (ITeamRepository) projectAreaHandle.getOrigin();



IWorkspaceManager manager = SCMPlatform.getWorkspaceManager(teamRepository);



Iterator<IChangeSetHandle> changeSetHandlesIter = manager.findChangeSets(sC, 10, null).iterator();

But as soon as line two should be executed my plugin hangs up. I don;t even have a stack trace or error message by now. :-(

Does anybody have any experience in running TeamConcert in headless mode still connecting to the team repository or does anybody have any hint ot manual for me.

I really appreciate your effort and help.

Thank you very much

Kim
