[Resteasy-developers] Error : Class is not a root ressource

[Jean-Baptiste M. <mes...@gm...>]

Hi,

I'm trying to use RestEsay and i have never could deploy my war.

I work with beta 6 + jboss 4.2.2 GA  + ejb3

first my EJB classes :

@Remote
@Path("/")
public interface IResultDaoRest {

    @GET
    @Path("/result")
    @Produces("text/plain")
    String getResults();

}

@Stateless
public class ResultDaoRest implements IResultDaoRest {

    @EJB
    IResultDao resultDao;

    @Override
    public String getResults() {
        System.out.println("getResult");
        return "result";
    }
}

@Remote
@Path("/")
public interface ILocatingRessource {
    @Path("locating")
    IResulDaoRest getLocating();
}

and its implementation

--------------------------------------------------------
my web.wml :


  <context-param>
        <param-name>resteasy.jndi.resources</param-name>

<param-value>JobTraker/ResultDaoRest/remote,JobTraker/LocatingResourceBean/remote
        </param-value>

    </context-param>

   <servlet-mapping>
      <servlet-name>Resteasy</servlet-name>
      <url-pattern>/*</url-pattern>
   </servlet-mapping>
</web-app>

------------------------------------------------

I have an EAR named JobTracker, and this naming context

+- JobTraker (class: org.jnp.interfaces.NamingContext)
          | +- ResultDaoRest (class: org.jnp.interfaces.NamingContext)
               | | +- remote (proxy: $Proxy520 implements
interface
com.linkdex.server.resteasy.dao.IResultDaoRest,interface
org.jboss.ejb3.JBossProxy)
         | +- LocatingRessourceBean (class:
org.jnp.interfaces.NamingContext)
               | | +- remote (proxy: $Proxy523 implements interface
com.linkdex.server.resteasy.dao.ILocatingRessource,interface
org.jboss.ejb3.JBossProxy)

---------------------------------------------------

When I deploy my EAR i have this error :

RuntimeException: Class is not a root resource.  It, or one of its
interfaces must be annotated with @Path: $Proxy538 implements:
com.linkdex.server.resteasy.dao.IResulDaoRest org.jboss.ejb3.JBossProxy
    at
org.jboss.resteasy.core.ResourceMethodRegistry.addResourceFactory(ResourceMethodRegistry.java:116)
[..]

somebody can help me  ?

Jean,

I am not sure you can do that directly with EJBs, maybe Bill can confirm it.

However, you can create a "Façade" for you EJB where you can use EJB 
dependency injection capabilities, and so you pojo can can access you 
EJB without problems.

Another architectural issue is that maybe your "Dao" returning String 
you may have problems in layers that are not suitable for REST, such as 
a Swing or even plain JSP pages (whatever JSF or Wicket).

Re: [Resteasy-developers] Error : Class is not a root ressource

[Bill B. <bb...@re...>]

Your web.xml is wrong.  Please take a look at:

https://resteasy.svn.sourceforge.net/svnroot/resteasy/tags/RESTEASY_JAXRS_1_0_BETA_6/examples/ejb-integration/

This example comes with the distribution.

Turn off scanning.  You must also manually define EJBs to register with 
RESTEasy using the "resteasy.jndi.resources" context-param.  Our 
documentation talks about how to do this.  If these changes don't work, 
let me know on this list.

<web-app>
    <display-name>Archetype Created Web Application</display-name>
    <context-param>
       <param-name>resteasy.jndi.resources</param-name>
       <param-value>
           JobTraker/IResultDaoRest/remote
       </param-value>
    </context-param>

    <!-- set this if you map the Resteasy servlet to something other than /*
    <context-param>
       <param-name>resteasy.servlet.mapping.prefix</param-name>
       <param-value>/resteasy</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>/*</url-pattern>
    </servlet-mapping>


</web-app>
