The dreaded "Servlet action is not available"

Hi all,










Here is my web.xml, can anyone see anything obviously wrong with it?

I have been trying to set up a new Struts project from scratch, and having set up a basic action class, etc I fire off a browser at my URL, and I get the dreaded "Servlet action is not available" error. As this message by itself is meaningless, I have been trying to hunt down the actual stacktrace in the tomcat logs to tell me what really happened, and here I have a problem: there are no tomcat logs, apparently tomcat v5.5 + eclipse + sysdeo plugin doesn't seem to work properly (logs go to /dev/null), still trying to debug this on the tomcat list. What will simplify things enormously is if I can be certain this error message is a Struts message or a Tomcat message, so that I don't go on a long wild goose chase. I am not sure whether the Struts servlet is even being called at all, as setting breakpoints within the struts ActionServlet class has no effect - the class never runs the init() method, nor the doGet() method. I also cannot find the text string "Servlet action is not available" in the Struts source code.
