RE: filter jsp:include servletPath?
Aaron, I am interested in doing the same thing. Can you post the filter and taglib?

Date: Wed, 27 Nov 2002 22:43:28 -0500 Hi all, This is more clarification about my attempts to automatically intercept and modify a .jsp request's servletPath as well as all the embedded jsp:include files. Examples: http://blah.com/index.jsp would run approot/blah/index.jsp or approot/default/index.jsp based on which was first found to exist. jsp:include page=/include.html/ would use approot/blah/include.html or approot/default/include.html based on which was first found to exist. I'm choosing a directory for the requested .jsp file based on the hostname specified in the request. I've gotten that to work perfectly by adding a filter to my web.xml file, and wrapping the request object before passing on to the next doFilter(). By overriding the request getServletPath() I can change the servlet or JSP file that gets invoked. Now I want the jsp:include files to also use an alternate directory. So refering to /myfile.jsp in the include would be intercepted and changed to another directory based on the hostname in the original request. Another view is that I'm creating a path to search through to find the requested (or included) file. If the requested file isn't found in the alternate expected directory, it checks in the default directory which will always have the file for request (or include). The code shows that once the request is filtered, all the jsp:include's are not. Private method ApplicationDispatcher.invoke() says: * IMPLEMENTATION NOTE: This implementation assumes * that no filters are applied to a forwarded or included resource, * because they were already done for the original request. Anyway, I'll let you read my original post below for more details on what I've found. BTW, I've searched long and hard for anyone doing this sort of thing. But, I'm certainly open to the embarassment of Oh, just do this if I've missed the obvious :-) Thanks, -AAron My original post: I'm trying to intercept a jsp:include so that I can adjust the requested file (ie: /include.html) to a different directory/file (ie: /otherdir/otherfile.html). If there is an easy way (Filter, Valve, Listener, ...) just let me know. NOTE: I've already created and installed a request filter in my web.xml to filter the initial request, but this doesn't get invoked for jsp:include references. Current idea: I want to change the javax.servlet.include.servlet_path request attribute so the DefaultServlet.getRelativePath() finds the new file. I can see that the ApplicationDispatcher fires off a list of InstanceEvent's before the DefaultServlet.service() is called. After days of exploration, I can't figure out how to add to get my InstanceEvent into the InstanceSupport's list (ie: cause a call to the support.addInstanceListener). Is there a configuration that will add my class to my application Context?

RE: filter jsp:include servletPath?
no, filters are only applied on the original request.

RE: filter jsp:include servletPath?
FYI, through more digging in google groups, I found out that the Java Server spec is vague on this issue. The new Java Server spec is going to explicitly allow two options. The default option will be that only the initial request is filtered. The other option will filter includes and forwards as well. -AAron From: Cox, Charlie [EMAIL PROTECTED] Reply-To: Tomcat Users List [EMAIL PROTECTED] To: 'Tomcat Users List' [EMAIL PROTECTED] Subject: RE: filter jsp:include servletPath?
