The question is not very clear. If I understood the question properly, put ur jsp in a folder say "MyJSP" in your app server root directory, and invoke the jsp from the client. A client could be a servlet or another jsp or a thin client such as web browser.
To do it from jsp you may have to use either sendRedirect or forward.
From servlet you can use RequestDispatcher to forward to the jsp or use sendRedirect as in jsp.
From the browser you can invoke using "http://host:8080/MyJSP/myjsp.jsp?parameters
if any" assuming the port number is 8080.
Hope this answers your question.
