This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I mapped my servlet to "/" and now no images or stylesheets can be found. Why is it grabbing every single request to the website? I only wanted it to grab "/" requests, but now it grabs ANY AND ALL requests to anything!
Ah, that's an old chestnut. The spec (still, as of 2.3, at least) implies that a URL pattern ending with '/' is treated as a prefix, and thus a pattern of '/' matches anything and everything. The usual way to solve it is to define a "welcome-file" in your web.xml which will handle the case of the user supplying just the '/', then map your active content to something else eg. web.xml:
Then put an "instant redirect" into your welcome file: index.html
This works for me. Apparently in version 2.4 of the servlet API, you can directly specify a servlet as the "welcome-file", so you don't need the jiggery-pokery with the redirect. I do really wish there was a way of specifying an "exclude pattern" of some sort, so I could say "send everything to my servlet, except URLs beginning with '/images'". Sigh.
Frank Is the web.xml file that you're updating the one in the default ROOT directory, or the one specific to your web app? I essentially want a url of www.mysite.com to fire up a specific servlet in my web application. I thought I could simply create an index.jsp file that merely forwarded the request to the desired servlet, and get the welcome-file to point to the index.jsp file. But when I type in www.mysite.com I still end up with the default Tomcat index.jsp file Something is obviously in the wrong place. Can you help? Thanks a mil Mark.
I don�t know if this applies to your situation but here is my two cents. If you�re deploying under apache your index.jsp will not get picked up. In that case you need to redirect your request to index.jsp from index.html.
