SAP System ID of SAP WAS

Hi Guys,

My intension is to retrieve the SAP WAS SID, for example when you go to SAP J2EE Engine Start Page e.g. (http://localhost:50000 ) and then System configuration and you can see System ID.

I would like to know how can i retrieve this ID programmatically.

Thanks in advance and looking forward to get your feedbacks.

regards
