Could you use the HTML <base> tag here? You could have it conditionally
generated to control its value in development, production, etc.

Subject: JSP -> servlet -> JSP request scope object passing
> This is no doubt a common question, but if I have a JSP page, that does =
> a FORM POST to a servlet, and that servlet's job is to do some parameter =
> checking, invoke the correct operations on beans/EJBs, then redirect the =
> user to the correct JSP page to display the results.
>
> If there's an error, the servlet sends the request back to the calling =
> page with an error set. If all's okay, it generally takes the person to =
> another JSP, though it may come back to the original JSP with a =
> "success" message.

> This JSP -> servlet -> JSP must a fairly common use.

> I'm having trouble getting this to work using "request" scoped beans. =
> When the first JSP is invoked, the request-scoped beans are created =
> until the page is returned. Then when the user clicks on the submit =
> button, the POST goes to my servlet. My servlet can create the beans =
> (such as an error response bean, and a page-specific bean that stores =
> the user's input so they don't have to re-enter anything if there's an =
> error), but if it puts them in the request object, a sendRedirect() will =
> cause the beans to be lost (new request). If I use the =
> requestDispatcher.forward() call, the beans are remembered, but the base =
> URL remains the servlet's URL, not the JSP page that is displayed.
>
> Aside from using session beans (which easily breaks down if the user is =
> actively moving about your site in two or more windows), how are people =
> handling this?
