java.lang.ClassCastException: org.jboss.ejb3.service.Service

dornus Oct 17, 2005 1:31 PM

I am trying to set up Dependency between MBeans and am getting an error I do not understand.

My Files

package ejb3.myPackage;

import org.jboss.annotation.ejb.Management;

@Management
public interface MyFirst {
 void doNothing();
}

package ejb3.myPackage;

import org.jboss.annotation.ejb.Service;

@Service
public class MyFirstBean implements MyFirst {
 private MyFirstBean() {
 System.out.println("My First Bean Service Loaded");
 }

 public void doNothing(){
 }
}

package ejb3.myPackage2;

import org.jboss.annotation.ejb.Management;

@Management
public interface MyOther {
 void doNothing2();
}

package ejb3.myPackage2;

import org.jboss.annotation.ejb.Depends;
import org.jboss.annotation.ejb.Service;

@Service
@Depends("jboss.j2ee:service=EJB3,name=ejb3.myPackage.MyFirstBean,type=service")
public class MyOtherBean implements MyOther {
 private MyOtherBean() {
 System.out.println("My Other Bean Service Loaded");
 }
}

Here is the error after I deploy the ear file

Strange. When I rebooted the server it worked fine. Guess I need to do that if I ever get this message again...

Are you using RC3? Remember, RC3 does not come with JBoss 4.0.3's installer, only RC2 does.

If you are using RC3, can you put together a simple app to reproduce this problem and post it on jira.jboss.com? I have had trouble reproducing this problem in the past.

I am using The 4.0.3 that came out in October. I guess it has RC3 in it?

My guess to what triggered it was when I was trying to access the properties file inside a war from an ejb3 file. Then I moved the properties file over to the ejb3 jar and redeployed without restarting the server. I tried numerous subtle changes to get the error to go away but no luck.

Then I eventually restarted the server and it went away.

If it helps, I have WinXP sp2, JBoss 4.0.3, MySql 5.0.13, Connector/J 3.1.11

no. 4.0.3 in October has RC2. I didn't coordinate with Scott very well...sorry.
