How to programatically find the reference r/3 system (for logon ticket)

Hi,

I have been able to find the list of systems in the portal runtime using code show below.

IUserMappingService iums = (IUserMappingService)PortalRuntime.getRuntimeResources().getService(IUserMappingService.KEY);

String str[] = iums.getAllSystems();

How do I find which system is the reference system defined in the portal among the systems listed.I have been able to even find out the list of attributes of the system.But this does not give me the Information I need.

Regards,

Harish
