Configuring web.xml for webservices and servlet - servlets

Question

I am new to Restlets. Trying to configure the web.xml (on JBoss). I have 2 entries, one for a servlet (got nothing to do with webservices) other for webservices, using Restlet. Here are the entries..
<servlet>
<servlet-name>AuthenticationServlet</servlet-name>
<servlet-class>com.safeid.web.server.api.servlet.AuthenticationServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>AuthenticationServlet</servlet-name>
<url-pattern>/authenticate/*</url-pattern>
</servlet-mapping>
<!-- Start of Entries for the REST Web Services. -->
<context-param>
<param-name>org.restlet.application</param-name>
<param-value>com.safeid.web.server.SafeIDRouterApplication</param-value>
</context-param>
<servlet>
<servlet-name>RestletServlet</servlet-name>
<servlet-class>com.noelios.restlet.ext.servlet.ServerServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>RestletServlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<!-- END of Entries for the REST Web Services.-->
Both don't work together. In the above setup the Restlet works. However when I change the
RestletServlet
/*
to something like
<servlet-mapping>
<servlet-name>RestletServlet</servlet-name>
<url-pattern>/credential/*</url-pattern>
</servlet-mapping>
the Restlet stop working and the AuthenticationServlet works fine. What am I missing here?

Answer 1

I had a similar frustration. Perhaps what I found out may help.
I had Router entries in my Application class like this:
router.attach("/users", UsersResource.class);
And things worked fine when my servlet mapping was like this:
<servlet-mapping>
<servlet-name>Sandbox</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
When I changed it to something like this:
<servlet-mapping>
<servlet-name>Sandbox</servlet-name>
<url-pattern>/users/*</url-pattern>
</servlet-mapping>
it stopped working.
The problem is that the servlet container "consumes" or removes the part of the URL that it matched. In this case, it removes "/users". So if you were using a url like this:
http://www.mywebsite.com/users
you would have to change it to be:
http://www.mywebsite.com/users/users
Of course, you can make the url-pattern be whatever you want:
<servlet-mapping>
<servlet-name>Sandbox</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
and then you'd access it like this:
http://www.mywebsite.com/rest/users
The url-pattern gets stripped off, and you get whatever is leftover in your Application class for your own routing purposes.

Looks like you're missing the init-params as in the example below.
<servlet>
<servlet-name>MyApplication</servlet-name>
<servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class>
<init-param>
<param-name>org.restlet.application</param-name>
<param-value>my.class.that.extends.Application.MyApplication</param-value>
</init-param>
</servlet>
You need a class that extends org.restlet.Application (at least in Restlet 2.0 anyway).
