EJB as Resteasy client -> ClassNotFoundException

korki Jul 30, 2012 2:34 AM

Hi all,

I am trying develop an EJB which is calling an external Webservice using the Resteasy Client Framework. It seems that the modules are integrated in the actual JBoss AS 7.1.1 delivery.

import java.net.URI;

import javax.ejb.EJB;
import javax.ejb.Schedule;
import javax.ejb.Singleton;

import org.jboss.resteasy.client.ClientRequest;


@Singleton
public class TimerService {
  
    @Schedule(second="*", minute="*",hour="*", persistent=false)
    public void doWork(){
        ClientRequest clientRequest = new ClientRequest("http://uriToMyWebservice:8080/rest");
        // OTHER CODE...      
    }
}

When creating a new ClientRequest I get the following Exception:

08:20:26,030 ERROR [org.jboss.as.ejb3] (EJB default - 3) JBAS014122: Error during retrying timeout for timer: [id=d2853aa7-780f-4565-bcf1-dbee60087c6c timedObjectId=server-core-0.0.1-SNAPSHOT.server-core-0.0.1-SNAPSHOT.TimerService auto-timer?:true persistent?:false timerService=org.jboss.as.ejb3.timerservice.TimerServiceImpl@28a29e6d initialExpiration=Mon Jul 30 00:00:00 CEST 2012 intervalDuration(in milli sec)=0 nextExpiration=Mon Jul 30 08:20:27 CEST 2012 timerState=RETRY_TIMEOUT: javax.ejb.EJBException: java.lang.RuntimeException: java.lang.ClassNotFoundException: com.sun.ws.rs.ext.RuntimeDelegateImpl from [Module "javax.ws.rs.api:main" from local module loader @7ab7b3f9 (roots: /opt/jboss-as-7.1.1.Final/modules)]

In my MANIFEST.MF I have added the following line:

Dependencies: org.apache.httpcomponents,org.jboss.resteasy.resteasy-jaxrs

Can anybody help me? How can I make things working?

Thx, Georg

I think I'm a little bit late for answer but I had same problem and solve it. Problem is that you add module but not export services (which placed into META-INF/services folder). There is two possibilities for exporting services:
If you use reaseasy client api in module you should add dependency to api with flag that services should be export too:
          <dependencies>
               ....
               <module name="javax.ws.rs.api" services="export" export="true" />
               ....
          </dependencies>

if you use it into deployment element that you can declare global module with the same flag or use jboss-deployment-structure.xml (https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7)

Hi Georg,

Did you resolve the issue as I am facing the exact same issue.

Thanks,

Alexey Volkov,

Thanks, your (first) solution works!... If possible, please explain the second possibility.

So, there is two sections in article:
"Global Modules": where placed information of how to declare global modules for all deployed application
"JBoss deployment sctructure file": where placed information of how to declare jboss dependencied for deployed application by placing special file inside ear (or war, jar etc).

Module with Reasteasy dependency can be declared by both of this ways. So all you need is two write <module name="javax.ws.rs.api" services="export" export="true" /> into stanalone.xml (in case of global module) or into jboss-deployment-structure.xml otherwise.
