Question

GWT RPC call don’t seems to work when i deploy my war file to TOMCAT (tomcat/webapps/ROOT/war).

It gives me an error:

The requested resource
(/war/myproject/call) is not
available.

If i change the directory structure and then deploy directly war contents (not war directory itself), like (tomcat/webapps/ROOT/project.html, project.css, project, etc…) then it works.

Can someone please explain me whats going on?

I think there might a problem at:

<servlet>
<servlet-name>callServlet</servlet-name>
<servlet-class>com.myproject.server.dao.Call</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>callServlet</servlet-name>
<url-pattern>/myproject/call</url-pattern>
</servlet-mapping>

The thing is that a single Tomcat server can have multiple applications deployed, each in its so-called context. The applications are deployed in the webapps folder and each folder is mapped to one context, while the ROOT folder is the default (no-context).

To access an application on Tomcat, you specify the context after the URL. For example if you had an application (context) Test in webapps/Test folder, you would access it like this:

http://localhost:8080/Test

But applications in the ROOT folder have no context and are accessed by simply going to localhost:8080. And this is your case. Tomcat is looking for you application directly in the ROOT folder but you have your app in the ROOT/war folder. In other words, the RPC call expects the myproject folder to be under the ROOT folder and not under the ROOT/war folder. That’s why it’s not working.

If you still wanted to have your war folder within the ROOT folder, you would have to change the url-pattern to /war/myProject/call.
