I was messing around with JAX-RS and made an application which calls REST services which produce JSON. I tried Jersey and everything went fine, but I had to switch to RESTEasy as my application needs to be built with JDK5. I changed my web.xml to something like this:
<web-app>
<context-param>
<param-name>resteasy.scan</param-name>
<param-value>true</param-value>
</context-param>
<listener>
<listener-class>
org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap
</listener-class>
</listener>
<servlet>
<servlet-name>RESTEasy</servlet-name>
<servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>RESTEasy</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
<!-- ... -->
</web-app>
So I expect every URL starting with /rest to be handled by RESTEasy. My services are as follows:
@Path("/services")
public class MyRESTServices {
@GET
@Path("service1")
@Produces(MediaType.APPLICATION_JSON)
public Object service1(Blah blah) {
}
}
This worked fine using Jersey, http://localhost/MyContext/rest/services/service1 was bound to my service1() method. When I change to RESTEasy, though, I had a 404:
HTTP Status 404 - Could not find resource for relative : /rest/services/service1 of full path: http://localhost/MyContext/rest/services/service1
Which means that RESTEasy handled the request but could not find any service bound to this URL.
On my class, changing @Path("/services")
to @Path("/rest/services")
worked, though. Do you have any idea why I got this strange behaviour? All the tutorials/docs I read mentionned only relative paths, not including the /rest prefix...
Solution: add the following in your web.xml
<context-param>
<param-name>resteasy.servlet.mapping.prefix</param-name>
<param-value>/rest</param-value>
</context-param>
Where /rest is the beginning of your <url-pattern>/rest/*</url-pattern>
