Hi @all,
I hope you can help me. I'm actually new to JBoss AS.
For the first test I have written a simple HelloJBoss application:
- HelloJBossAS7 (eclipse ear project contains the two following projects)
- HelloJBossEJB
contains:
ISimpleEJB.java
package de.example.ejb;
import javax.ejb.Local;
@Local
public interface ISimpleEJB {
int add(int a, int b) throws Exception;
}
SimpleEJB.java
package de.example.ejb;
import javax.ejb.Stateless;
@Stateless
public class SimpleEJB implements ISimpleEJB {
@Override
public int add(int a, int b) throws Exception {
return a + b;
}
}
- HelloJBossJSF (2.0)
contains
Content.java
package de.example.beans;
import java.io.Serializable;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import de.example.ejb.ISimpleEJB;
@ManagedBean
@SessionScoped
public class Content implements Serializable {
private static final long serialVersionUID = 5526381952953438091L;
private String title = "Hello JBoss AS 7 :-)";
@EJB(beanName = "SimpleEJB")
private ISimpleEJB ejb;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public int getVal() {
try {
return ejb.add(2, 4);
}
catch (Exception e) {
return -1;
}
}
}

If I delete the ejb-member "ejb" in the Content class, I can deploy the EAR to the jboss and the jsf app work's fine. But if I use the "ejb" member, I will get the following deployment error:
23:54:13,542 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC00001: Failed to start service jboss.deployment.subunit."HelloJBossAS7.ear"."HelloJBossJSF.war".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.subunit."HelloJBossAS7.ear"."HelloJBossJSF.war".INSTALL: Failed to process phase INSTALL of subdeployment "HelloJBossJSF.war" of deployment "HelloJBossAS7.ear"

Is using the @EJB annotation the wrong way? Should I user instead a ServiceLocator?! I hope, someone can help me and tell me the correct way to use the SimpleEJB.
Who want's to see the whole project's, have a look the the attachment.
Thank you for support! :)
