Embedded EJB3 Services

[majohnst]

I am trying to learn EJB3, so I downloaded the Embedded version and I am running the samples through JUnit in Eclipse. I have the tutorial examples of entity beans working fine. But I can't get a @Service bean to load.

Here is my service

public interface IndexerMBean {

 public String getResults();
 void create() throws Exception;
 void start() throws Exception;
 void stop();
 void destroy();
}


@Service
@Management(IndexerMBean.class)
public class IndexerService implements IndexerMBean {
 protected static final Log log = LogFactory.getLog(IndexerService.class);

 private String indexDir;
 private String results = "my results";

 public String getResults() {
 return results;
 }

 public void create() throws Exception
 {
 System.out.println("ServiceOne - Creating");
 }

 public void start() throws Exception
 {
 System.out.println("ServiceOne - Starting");
 }

 public void stop()
 {
 System.out.println("ServiceOne - Stopping");
 }

 public void destroy()
 {
 System.out.println("ServiceOne - Destroying");
 }

}

When I run my junit test based on the tutorial examples, I get the error message

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

Does anyone know what causes this error?

Haven't really tested @Service, @Consumer within embedded environment. @Management won't work because it is looking for a JBoss MBeanServer, but I think @Service without a @Management interface will work. I'll put this on the todo list.

I do think the docs that come with the dist say that only SFSB, SLSB, and MDB have been testesd with embeddable stuff.

Apologies. But it is an alpha release...

Thanks for the response. Since I am trying to learn EJB3, I thought the embedded version would make it quicker since I don't have to package, deploy, test everytime I make a change.

Is there any other way to test EJBs outside of JBoss? Somehow through JUnit?

[bill.burke]

@Service is a JBoss specific extension to EJB3. SFSB, SLSB, EM, MDBs still work in embedded EJB3. I will get it to work in the next release.

If you don't use embeddable EJB3, you're gonna have to write a lot of mock objects.
