Get Part Information where i am on for JSP Site

Hello Guys,

i created a customized subtab with a link to a new created JSP Site. On that page i want to show some additional informations which i get from the class which i have written for that actions. It works fine for simple return functions. But now i want to pass the Part to the functions, but how do  i get the WTPart Information from the current Part Page where i am on?

Thank you for help in advance

Best Regards,

Daniel
