Deploy GWT to Tomcat (servlet not running)

What is the correct way to deploy a GWT app to Tomcat? I have made a GWT app with server side code (servlets). It works in Hosted mode but only when I copy the WAR folder (after compiling) to Tomcat webapp directory and rename the war folder correctly.

My GWT app servlet is in URI /mygwtapp, so I renamed the folder mygwtapp. The app loads correctly with the problem that servlet do not run i.e. /mygwtapp/servlet does not run.

All the libraries needed by the server side code are in the WEB-INF/lib folder. What could be the reason for this?

Thanks.

One other option is to use GWT.getModuleBaseURL() then in your client side code append servlet name. This will make it work on jetty or Tomcat without any special config.

By default, Tomcat serves an app named 'mygwtapp' from the context path '/mygwtapp'. (Whereas the GWT built-in jetty serves it from the context path '/'.)

Your servlet paths will usually be '/mygwtapp/*'. This means, that in conjunction with the context path, your servlets are now accessible from '/mygwtapp/mygwtapp/*'. (Try it: Simply enter the full URL in your browser - the Servlet will usually complain that something is missing, or that it doesn't support GET, but you'll know for sure now, where it lives.)

So you have two options:

  1. Tell the client side to call the servlets at '/mygwtapp/mygwtapp/*' (I think, this is already taken care of automatically when using the @RemoteServiceRelativePath annotation)
  2. Adjust the Context path of the web application in Tomcat, as explained in http://tomcat.apache.org/tomcat-6.0-doc/config/context.html
