How to pass a request variable to a frame set
Hi all, I have a java clas called PlanAction.java. I am forwarding to a JSP called Offerings.jsp. But Offerings.jsp contains a frameset which include another JSP called Plan.jsp. I need the request attribute set in the PlanAction.java to be available in the Plan.jsp. I found that request attribute is available in Offerings.jsp but not available in Plan.jsp. Is there any method to get the request attribute in Plan.jsp Regards, Krishna - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to pass a request variable to a frame set
There's no way to do it that is Struts-specific, uhh, unless I'm wrong :) You have to think about what is happening on the browser when PlanAction.java completes and fowards... The response is returned to the browser, Offerings.jsp. This page loads content, Plan.jsp. So, as far as the browser is concerned, anything that was passed to the server as part of Offerings.jsp's response (and request by extenion) is separate from the NEW request for Plan.jsp. It's two different requests as far as the browser (and server) is concerned, hence you won't find anything that was in request scope during the first request it in request scope for the second request. There's a couple of ways you could handle this... One is that in Offerings.jsp, where you specify the source Plan.jsp for the child frame, pass the attribute along with it, something like this: frame name=planFrame src=/jsp/Plan.jsp?myParam=%=request.getAttribute(myParam)% Then, in Plan.jsp, you can now access myParam as you would any other parameter. Another option is to use scripting to get at the variable. In other words, in Offerings.jsp, do this in a script block in your header: script myParam = %=request.getAttribute(myPAram)%; /script Then, in Plan.jsp, you can do this to get that value: script myParam = parent.myParam; /script The first keeps everything in JSP code, the second is client-side. Depends on which you need or prefer. I've done both for various reasons in various cases. -- Frank W.

Re: How to pass a request variable to a frame set
In fact there could be another solution. You could extend the html:frame tag, by adding an attribute that propagates the request parameters. In fact html:frame can use a java.util.Map to create the URL query parameters but it cannot use the current parameters. Normally you have to do this way: html:frame page=/jsp/myFrame.jsp name=nameOfTheMapAsAttribute / where nameOfTheMapAsAttribute is a java.util.Map stored in some scope (request, session, application). The problem is that the current parameter map can be taken with the method getParameterMap of HttpServletRequest and is in no scope! Maybe it can be a future feature for Struts...
