connect siebel 2321 from java applet

   Hello, all.

Did anybody try to use Siebel Java Data Bean (on port 2321) from Java applet in Siebel?

I have to do the following:

1) upload a file from local disc c:\ using my own applet, displayed in Siebel

2) create or update Business Components in Siebel according the uploaded file.

There is no problem to communicate the service on port 2321 with this connect string

m_dataBean.login("Siebel://SiebelServerhost:SCBPort/enterpriseServer/AppObjMgr_enu", USERNAME, PASSWORD, "enu");

But.. how can i obtain USERNAME and PASSWORD of the user that logged into Siebel and loaded my applet?

Any advice will be appreciated

Best regards
