From a JSP called "ABC.jsp", when I click "View Item" button it should call corresponding action class,process and display results(displayitems.jsp) in a popup window. for some reason if the result is error page or login page then the popup window should not be opened rather it should replace ABC.jsp in main window.
i.e. If result is displayitems.jsp I want to open this jsp in pop up window and keep ABC.jsp open in main window. If result is some other page I want to replace ABC.jsp with result page in main window.
how to do this opening the popup window conditionally i.e. based on result page?
You really can't do it in quite this way. The problem is that you must decide where the result is to be displayed before you submit. You can't change your mind once the submit has already occurred.
I can think of work-around solution, though. There is a way to tell whether or not the current window is a popup window. If it is a popup window, the property window.opener will have a value other than null. Otherwise, it will be null.
In your error page in the body's onload event, test window.opener to see if it's null. If it isn't null (meaning this is a popup window), cause the main window to load the error page (window.opener.location.replace('error.jsp');) and close the current window.

But the problem is, there are some on the fly validation messages(generated by struts validation.xml) which I am missing while displaying login.jsp page in case of the above scenerio. (window.opener.location.replace('login.jsp')
do you have idea how to display whatever page we are getting for popup window to main window?
