How to use the Jazz JUnit test cases?

I have set up a Jazz component development environment. When I try to launch a Jazz JUnit Plug-in Test, e.g. com.ibm.team.process.internal.ide.ui.tests.ProcessIdeEditorTests, I get an exception "TeamServiceException: return code 503 from HTTP request: Service 'com.ibm.team.repository.common.tests.IScheduledTaskControllerService' is not accessible remotely". I just use the default Jazz server configuration in local. What should I do for solving this problem? The detailed exception trace is atached as below. Thanks in advance!
