Hi Peter, as i wrote back to you i only recalled what i had in memory...
First, for a simple but in my opinion good description of the url-pattern syntax have a look at: http://www.roguewave.com/support/docs/leif/leif/html/bobcatug/7-3.html That leads to the possible Answers for the Question, how to load images and make the URLīs short. The problem is, you have to map specific urls to your servlet, Turbine in this case. You want to exclude static resources, of course. The description above tells clearly, you can only match simple URL Patterns. It would be nice to match against Regular Expressions (sth. like /.*?[.]vm.*/ would do the trick, maybe hack sth the like in your Tomcat ;-) but that is no immediate Solution. In my opinion the solution is fiddling around with the matching algorithm of the Servlet Container and the url-patterns. You could do like this: <url-pattern>/resources/*</url-pattern> map to a dummy Servlet that just opens the requested File and writes it back to the browser. <url-pattern>/*</url-pattern> maps to the Serlvet of Turbine itself. "Since the container prefers to match the longest pattern", the first one will succeed for all of your Images, CSS and stuff thelike whereever the URL is invisible to the user (embedded in HTML) and all other URLs map transparently to your servlet. I think i have once seen such a solution, but there are several things to note: - I am not sure if this is a major performance drawback. In fact i donīt think so but you will have to compare... - You would not want your system security be that easy to break like /resources/../../conf/server.xml ... so the dummy Servlet has to check. - I thought there were more possibilities in the url-pattern syntax, but there are none. In fact, i would love a more understandable and flexible approach for mapping servlets in servlet containers. How much time i spent until that d$#m Web.xml file worked... - This is a hack. Please report any better solutions. Maybe this helps.
