debugging JAX-RS service registration on jboss AS 7.1

Question

I have setup a very simple test application to try RESTeasy on Jboss AS 7.1.

Environment:

• jboss-as-7.1.0.Final
• eclipse 3.7 with Jboss Tools
• maven 3

I followed the steps in the tutorial but did not get the same result. The webapp is deployed correctly and it appears in the admin console but it does not work as intended.

The server invariably tells me 404 Resource not available when I try to access http://localhost:8080/SeamSertalVision/services/test

There are 4 files in the whole project:

• pom.xml
• web.xml
• RestApplication.java
• Login.java

the pom.xml has one dependency which resolves fine:

</project>

the web.xml is empty:

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.5"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <display-name>Sertal Vision</display-name>

</web-app>

the RestApplication.java is empty:

package ch.sertal.vision.server;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/services")
public class RestApplication extends Application {
}

the Login.java contains just one method for testing:

package ch.sertal.vision.server;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path( "/test" )
public class Login {

   @GET
   @Produces(MediaType.TEXT_HTML)
   public Response login()  {
      return Response.ok( "logged in" ).build();
   }

}

that's the whole thing, as it was described in the tutorial (I believe). The deployment works fine. If I add a welcome-file entry to the web.xml it is displayed.

here is the jboss log after teh application is deployed:

My question is: how can I verify that my Webservice is being registered? There is no hint to his in the log but no error either. There must be something wrong but I can't see what it is.

I have an application on Tomcat with Jersey and there the log clearly shows which classes perform RESTful services.

thank you for your help.

You will not see if the REST service is registered during startup because the service only starts on-demand, then you will see something like this:

INFO  [org.jboss.resteasy.cdi.CdiInjectorFactory] (http--127.0.0.1-8080-1)
      Found BeanManager at java:comp/BeanManager
INFO  [org.jboss.resteasy.spi.ResteasyDeployment] (http--127.0.0.1-8080-1)
      Deploying javax.ws.rs.core.Application:
      class my.rest.JaxRsActivator$Proxy$_$$_WeldClientProxy

I don't see a significant error in your configuration, but it's possible that you are missing a WEB-INF/beans.xml?

To get a working example of a JBoss7 with a REST service you can create a new project using the following archetype: org.jboss.spec.archetypes:jboss-javaee6-ear-webapp:7.0.2.CR2 (you have to change the version of all JBoss dependencies from 7.0.2.CR2 to 7.1.0.Final).
