Re: OT?:Can't include .js file on jsp page controlled by front controller servlet
What does the js in your JSP do and how are you including it? Some text from your JSP might help. [EMAIL PROTECTED] 01/12/04 09:58AM I may be getting in over my head here as I'm really not all that familiar with patterns. And I'm not sure that the pattern has anything to do with problem. But I have a controller servlet through which all web requests must pass. It has worked fine as is. Until I tried to include a .js file on a jsp page. In that case it seems to either print it out to page, rather than execute it, or it tries to use requestDispatcher portion of controller servlet to forward/include it. Normally the requestDispatcher forwards request to the requested page after it checks to see if user is logged in. But now it seems to go into an infinite loop when forwarding. And I guess it's trying to use requestDispather.include because the .js resource is included via a src='http:...' request. I know that this is a very vague question but I wonder if anyone has any clues as to where the problem might lie or what I can start experimenting with. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Front Controller Servlet
The reason it is crashing is because you are forwarding to a JSP page, however you have already taken over jsp processing in your servlet by declaring that it should handle *.jsp, thus it forwards in a circle until it runs out of stack space. Try using another extension for your controller, such as .ktx as we use in ours. This can then forward sucessfully to jsps! Should be: servlet-mapping servlet-nameFCservlet/servlet-name url-pattern*.ktx/url-pattern /servlet-mapping Then your links can be to index.ktx instead and it will got through ok.

Re: Front Controller Servlet
I agree that the design isn't the greatest (but I've seen much worse ;-). To
do what you want, in FCServlet try something like:
if(request.getServletPath().endsWith(.jsp)) {
RequestDispatcher rd = getServletContext().getNamedDispatcher(jsp);
rd.forward(request, response);
return;
}

and when he uses the Forward method , the tomcat activate my

RE: Front Controller Servlet
That's because you're trying to implement as front controller **servlet** as a JSP ? Map your controller servlet to /foo (or anything *other* than *.jsp) then requests could all go to the controller servlet, and your servlet could send it off to any *.jsp page without invoking itself infinitely. -Original Message- From: Sharon Cohen [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 05, 2003 7:43 AM To: [EMAIL PROTECTED] Subject: Front Controller Servlet I am trying to build FrontController servlet for a web site on Tomcat 4 , after long time of changes on the web.xml file , I wasn't able to achieve this pattern, the web.xml portion is : servlet-mapping servlet-nameFCservlet/servlet-name url-pattern*.jsp/url-pattern /servlet-mapping my problem start when the FrontController servlet needs to forward the request to other jsp pages and when he uses the Forward method , the tomcat activate my FrontController again , and after a while I get : StackOverflowError .
