Re: help on a servlet issue
Can you post the code for the servlet you're trying to add? Also, when you say that you added a new servlet for the setup module, what exactly do you mean? How are you associating the servlet with your module?

help on a servlet issue
hi, sorry, I am a newbie on this. I used eclipse to create the project, and I added a new module called setup (so I have two modules) then I tried to add a new servlet for the setup module, but I got the following error message, if I add a servlet for the original module, it will be fine. GWT document does not seem to have much document to discuss multiple modules. Here is the web.xml that I used for new servlet for the new module testServlet com.simon.chutian.store1.server.TestServiceImpl adduserServlet /setup/adduser my new module is renamed to "setup", I directly added the new module in the existing project. I think there must be something wrong with the path settings or maybe the servlet mapping, Can anyone help?
