Seam 2.1.1.GA RESTEasy problem

nhhagen Jan 22, 2009 1:29 PM

I'm using the integrated REASTEasy implementation that came with seam, and I get the following error when I access the resource with a browser:

The url used to access the server:

}

The interface:

@Local
public interface RestResource {
     
     // seam-gen method
     public void restResource();
     
     public String method( String station, String date );

}

I've tried to google the 2 error message but without getting any luck with the results. Any help with this would be greatly appreciated.

Your implementation has..

public String getShelfLife

Your interface has...

public String method

Sorry for that, just an editing error when posting trying to make the post as generic as posible (I realize that I might have been to tired):

in the real files

Interface is: public String getShelfLife
Implementation is: public String getShelfLife

Pasting interface and implementation one more time (direct from source).

Interface:

package com.tracetracker.cci.session;

import javax.ejb.Local;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.ProduceMime;

@Local
public interface GqiResource {
     
     // seam-gen method
     public void gqiResource();
     
     public String getShelfLife( String station, String date );

}

Bean:

package com.tracetracker.cci.session;

import javax.ejb.Stateless;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.ProduceMime;

import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Name;

public class GqiResourceBean implements GqiResource {
     @Logger
     private Log log;

     @In
     StatusMessages statusMessages;

     public void gqiResource() {
          // implement your business logic here
          log.info("gqiResource.gqiResource() action called");
          statusMessages.add("gqiResource");
     }
     
     @GET
     @Path("/getShelfLife/{station}/{date}")
     @ProduceMime("text/plain")
     public String getShelfLife( @PathParam("station") String station, @PathParam("date") String date ) {
          return "This is a test, station: " + station + " date " + date;
     }

I could really need some help on this issue. Has anyone come across the same error before

I encountered this problem myself. Here is what I think is happening. Seam creates an instance of the 'restResource' component by obtaining an instance from JNDI. What it gets back is an EJB stub that implements RestResource, not an instance of RestResourceBean. However, it is RestResourceBean that is annotated and not RestResource. As a result Resteasy is trying to invoke methods on what it thinks is a RestResourceBean. This of course fails and you get the 'object is not an instance of declaring class' error.

Did you try placing the JAX-RS annotations on RestResource? I think the problem there is going to be one of discovery -- seam/resteasy might not find the JAX-RS annotations on the interface.

When I annotate the local interface instead of the bean I get the following exception on deploy:

2009-02-10 18:27:27,532 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/jcourse/SeamTest]] Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener org.jboss.seam.InstantiationException: Could not instantiate Seam component: org.jboss.seam.resteasy.dispatcher at org.jboss.seam.Component.newInstance(Component.java:2106) at org.jboss.seam.contexts.Contexts.startup(Contexts.java:304) at org.jboss.seam.contexts.Contexts.startup(Contexts.java:278) at org.jboss.seam.contexts.ServletLifecycle.endInitialization(ServletLifecycle.java:112) at org.jboss.seam.init.Initialization.init(Initialization.java:735) at org.jboss.seam.servlet.SeamListener.contextInitialized(SeamListener.java:35) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3856) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4361) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:790) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:770) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:553) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)

with the cause being:

The ArrayIndexOutOfBoundsException exception suggests that it is finding the component, but not the JAX-RS annotations on its interfaces.

apparently, based on the jboss docs, you should be annotating your interface, not implementation. didn't know that myself either, but came up as the first hit when i searched on the google for resteasy ejb

That indeed is the problem. See:

https://jira.jboss.org/jira/browse/JBSEAM-3938
and
https://jira.jboss.org/jira/browse/JBSEAM-3449

Looks like the problem will be resolved soon.

Annotated interfaces work just fine if you use the GA release of RESTeasy standalone.
