Hi, I'm not sure that I understood what you wrote. Of course, I have a reference to the servlet library in the properties of my jbuilder project :) Why shouldn't I have that reference (in the required libraries) ?
Sorry, if I misunderstood your reply but I'm just a newbie in the development of Web Application. For the rest, I tried deploying my webapp with Tomcat and I had the same problem (!!!). So I'd suppose, it's a Tomcat problem (or a Struts prob ?). I also patched my Jbuilder 6.0 with the latest update available without any improvement. I didn't try to update my version of Tomcat. Because I first wanna be sure it's Tomcat causing the problem and not something else...
