Filter to redirect to welcome action when pre-compiling JSPs
I have been playing around with JSP pre-compilation with Tomcat-4.1.24 (http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jasper-howto.html) so I can check my JSP pages for compiler errors before deployment, but also to remove the delay that the first hit incurs. The only problem with this is the welcome-file which has to point to a physical jsp page and not a servlet. The Struts in Action book suggests using a index.jsp page with a logic:redirect to a Welcome action, which is what I was doing. I tried creating a servlet that would forward the request onto my Welcome action servlet-mapping with a url-pattern/url-pattern, but this seemed to match any request and cause lots of problems. So I dropped that idea and instead have used a filter... filter-mapping filter-nameWelcomeFilter/filter-name url-pattern//url-pattern /filter-mapping which works perfectly. It only fires for http://localhost/app/ or http://localhost/app and my filter forwards the request onto my Welcome action correctly. I can now get rid of index.jsp and all my other JSPs are pre-compiled. I have also hidden all of my JSPs under the WEB-INF so they cannot be called directly and have to go through my Struts actions.

Cool. It's good to know someone else has done this. I thought I should post this just so someone else looking at pre-compilation of JSPs would find it useful, but also to see if there are any glaring issues or if it is a Good Thing (TM) :-) Jason David Graham wrote: This is exactly what I did :-).

Re: Filter to redirect to welcome action when pre-compiling JSPs
Hi Jason, At this very moment, I am trying to solve a similar issue. Would you mind posting the relevant snippets from web.xml and struts-config? Such as paths to actions, url-pattern, etc. Thanks Al On Mon, 2003-03-24 at 22:01, Jason Lea wrote: Cool. It's good to know someone else has done this.

It's easier to maintain than a bunch of one line index.jsp files that redirect to another page and it gave me an excuse to learn more about filters :-).
