I got NullPointer Exception when I test my ejb (EJB3.0 version) using Junit with Cactus

[Alice Liu]

HI,

 

 My code is like this.

 

public class SampleFacadeTest extends ServletTestCase {

 

    @EJB

    SampleFacadeLocal sampleFacade;

 

    public void setUp() {

        

    }

    

    public static Test suite()

    {

        return new TestSuite(SampleFacadeTest.class);

    }

    */

 

    public void testFind() throws Exception{

        String firsName =  "Rick";

        String testName = sampleFacade.find(112233).getFirstName();

        assertEquals(firsName , testName);

    }

    

     

 

}

 

The sampleFacade variable got null pointer exception at line

 

String testName = sampleFacade.find(112233).getFirstName();

 

EJB3.0 is new thing. I wish I could get answer from here.

 

Thanks.
