    Do you have the API doc for that? I would look there.
    If you don't understand my answer, don't ignore it, ask a question.

    it is not API, just jsp.



    my project requirements is as below,

    1. create a logon jsp page with userid and password field
    and create 2 button , abnormal and normal button respectively. once the user click on it , it will submit form to servlet. it will redirect to the page home.jsp after successful logon.
    2. form home.jsp, I want to prompt a popup window when home.jsp is redirected from logon.jsp and triggered from normal button? NOT triggered by abnormal button.
