your question is very general.
for executing  the jsp  page form weblogic  , u should know about the
web application and how to deploy web application on web logic.

While deploying the web application on WEblogic it will ask u about
the context root and some othet fields


if u need some reference on that , let me know or u can refer to
www.weblogic.com/docs51/classdocs/API_jsp.html
