java.lang.NullPointerException with EJB 3 stateless web ser

longbeach Sep 8, 2008 5:09 PM

Hi,
I get an error while deploying a Stateless session bean defined as a web service on JBoss 5 CR1.
It seems to be a problem of version of JRE since it works with JRE 5 but does not work with JRE 6.
I am using Eclipse 3.4

My interface looks like this :
@WebService
@SOAPBinding(style = Style.RPC)
public interface Test extends Remote {
...
}

My bean looks like this :

@Stateless
@WebService(endpointInterface ="Test")
@Remote(Test.class)
public class TestBean {
...
}

It deploys with jre 1.5 but it fails miserably using jre 1.6. Here is the stack trace (the web services are developped inside the VenteEnLigneEJB project, with Eclipse 3.4):

And the version of java that i use :

22:17:15,871 INFO [CopyMechanism] VFS temp dir: D:\EJB3\jboss-5.0.0.CR1\server\default\tmp
22:17:15,885 INFO [ZipEntryContext] VFS force nested jars copy-mode is enabled.

22:17:16,787 INFO [ServerInfo] OS-System: Windows Vista 6.0,x86

If i comment out the annotations @Webservice on the class AND the interface, it deploys correctly, no error.

Does anyone know what is wrong here ?

Thanks

I don't know how you got this working on jre 1.5. I tried out a simple example in my application:

package org.myapp.webservice;

import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

@WebService
@SOAPBinding(style = Style.RPC)
public interface AppService {

 void sayHello(String user);

}

package org.myapp.webservice;

import javax.jws.WebService;

@WebService (endpointInterface="org.myapp.webservice.AppService")
public class AppServiceImpl implements AppService {

 public void sayHello(String user) {
 System.out.println("Hello " + user);

 }


}

Packaged this in a EAR file and placed it in deploy folder of JBoss-5 CR1 with JDK 1.5

13:54:30,148 INFO [ServerInfo] Java version: 1.5.0_10,Sun Microsystems Inc.

13:54:30,257 INFO [ServerInfo] OS-System: Windows 2003 5.2,x86

Started JBoss. But the startup failed with the same exception as what you see:

Going by the logs, this looks like deployment ordering issue in CR1.

As a workaround, i stopped JBoss. Removed the EAR from the deploy folder of JBoss. Then started JBoss (without the EAR file). Once the server had started successfully, i copied the EAR containing this webservice to the deploy folder. The hot deployer picked up the deployment and successfully deployed the applicaiton.

Another workaround is to create a folder named "deploy.last" in %JBOSS_HOME%/server/default/deploy and place your application in that folder and start JBoss.

Just found this JIRA https://jira.jboss.org/jira/browse/JBWS-2246 which talks about a SAR deployment failure. Seems applicable to EAR deployment too.

hi,
i tried what you did, using JRE 1.6

I removed the ear, started JBoss 5, then i copied the ear file and the deployment works.
Thanks. That seems to help.

I have not tested it yet though. Hope there is no problem.
