Java script problem in JSP called thru servlet

Question

when jsp page is displayed thru a servlet in following way the java scripts built in that JSP page are not working.
ServletContext sc = getServletContext();
     RequestDispatcher rd = sc.getRequestDispatcher(url);
     rd.include(req, res);
how can i enable these java scripts?

Answer 1

Most probably you have something like this:
<script language="JavaScript1.2" src="menu.js"></script>
The bit that is probably causing the problem is the src attribute.
Its a common issue when using the request dispatcher
You request "/servlets/myServlet"
it forwards to "/jsp/myJSP"
You try and access a resource using a relative URL.
however, the browser knows nothing about the forward being done - it thinks that the URL is /servlets/myServlet, when you want it to be /jsp/myJSP.jsp
So if you access menu.js it will look in /servlets/menu.js instead of /jsp/menu.js (example only)
to fix
1 - Don't use relative links. Ie use /scripts/menu.js to import the script
2 - use a <base> tag <base href="http://www.mywebsite.com/jsp/> This tells a web page where to resolve relative references from.
Hope this helps,
