For tests of some small JBoss enterprise apps I would like to use JUnit, and the Maven Cargo plugin. (I know that there is also JSFUnit but first I would like to take a closer look at Cargo.)
Is there a simple example available online which I could use as a reference for running a JUnit test which invokes a EJB operation using JBoss (4.2 or 5.1) using the Maven Cargo plugin? I have found some good introductions to the configuration, but I get error messages in the EJB lookup so it would be helpful to see how it should be used.
Here is the test code using InitialContext:
public void testEcho() {
assertEquals("Echo Echo", lookupEchoBeanRemote().Echo("Echo"));
}
private EchoBeanRemote lookupEchoBeanRemote() {
try {
Context c = new InitialContext();
return (EchoBeanRemote) c.lookup("EchoBean/remote");
} catch (NamingException ne) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", ne);
throw new RuntimeException(ne);
}
}
Which gives this error:
testEcho(de.betabeans.Echo2Test) Time elapsed: 0.885 sec <<< ERROR!

If I use the EJB annotation
@EJB(beanInterface=EchoBeanRemote.class,mappedName="EchoBean/remote")
private EchoBeanRemote newSessionBean;
public Echo3Test(String testName) {
super(testName);
}
public void testEcho() {
assertEquals("Echo Echo", newSessionBean.Echo("Echo"));
}
The test result is
testEcho(de.betabeans.Echo3Test) Time elapsed: 0.001 sec <<< ERROR!
java.lang.NullPointerException

jndi.properties is located in the EJB jar root folder and contains these lines:

The bean source code is
package de.betabeans;
import javax.ejb.Remote;
@Remote
public interface EchoBeanRemote {
String Echo(final String in);
}
package de.betabeans;
import javax.ejb.Stateless;
@Stateless
public class EchoBean implements EchoBeanRemote {
public String Echo(final String in) {
return in + " " + in;
}
}
I have also tested a web application which can call the EJB without problems - in both ways, with InitialContext or an annotation. A warning which I received in the deployment of the web application was
WARN [MappedReferenceMetaDataResolverDeployer] Unresolved references exist in JBossWebMetaData:[#web-app:AnnotatedEJBReferenceMetaData{name=de.betabeans.Echo3Servlet/echoBean,ejb-ref-type=null,link=null,ignore-dependecy=false,mapped/jndi-name=EchoBean/remote,resolved-jndi-name=null,beanInterface=interface de.betabeans.EchoBeanRemote}, #web-app:AnnotatedEJBReferenceMetaData{name=NewServlet/newSessionBean,ejb-ref-type=null,link=null,ignore-dependecy=false,mapped/jndi-name=NewSessionBean/remote,resolved-jndi-name=null,beanInterface=interface de.betabeans.NewSessionBeanRemote}] 12:26:11,770 INFO

I have uploaded the complete Maven project now to http://www.mikejustin.com/download/JBossSimpleEJBApp-ejb-test.zip
