HiJazzService tutorial step 6 problem

I tried the HiJazzService tutorial and first 5 steps work correctly and I get the expected results. But the 6th extra credit step doesnt work.

When I click on the IHiJazzService in the service list on the server, I get the following error:

CRJAZ1173I Service "com.example.hijazz.service.IHiJazzService" is not available.

When I try https://127.0.0.1:9443/jazz/service/com.ibm.team.repository.service.IRepositoryItemService, I got the following error:

CRJAZ1168I Service "com.ibm.team.repository.service.IRepositoryItemService" is not defined for remote execution.

The server seems to be running fine otherwise. Please help
