passing request to a second jsp
Hi Guys
I have a jsp (search.jsp) that deals with a request from a web form and shows the results in the browser. Im then trying to pass this request to a second jsp (export.jsp) to put the info into an xls file. I can create an xls file on its own by setting the contentType but i cant show the results in a browser and then pass the request to export. Ive read loads of foums and tried jsp:forward and jsp:include both of which dont work. I have also tried requestDispatcher and sendRedirect but cant get it to work.
This is the main problem
Provide a href link capable of either calling export.jsp and passing the request or providing a href link to call a method in search.jsp that will then use a method to pass the request and forward the user.
I have been stuck on this for ages now and have had zero luck. If anyone can help me and provide some sample code that would be brilliant.
Thanks

Put the request in a session variable.
In the first page do
request.getSession().setAttribute("var", yourData);
and in the second page, just get the data from the session
request.getSession().getAttribute("var");

yes, it may be anything. HashTable/ArrayList/String/int/boolean/etc.,
String myVar = myBO.getVal();
session.setAttribute("value", myVar);
JSP:
String getData = (String)session.getAttribute("value");

Hi im actually trying to pass the request (a HttpServletRequest object) but when i use the methods suggested above i get an error cannot cast from Object to [type].
I could do the task by passing a formdata object (my own class) and a boolean instead of the request.
I have tried with a boolean and the HttpServletRequest but always get the same error!

Hi Everyone
I have finally got it all working in the end i used a combination of all your advice.
I put all the variables i needed into an object and just passed that using set/getAttribute("value") which worked for my FormData object but would not work for a boolean or HttpServletRequest!
Stars all round!
