Hello all,
I am getting start to EJB 3.0 with a HelloWorld, but I got the following
exception:
java.lang.ClassCastException: org.jnp.interfaces.NamingContext
I am using NetBeans 5.5 Preview, JBoss 4.0.4.CR2 with EJB3.
Here is my HelloWorldBean:
| package hi;
|
| import javax.ejb.Stateless;
|
| @Stateless(name="HelloWorld")
| public class HelloWorldBean implements HelloWorldRemote {
| public String sayHi (){
| return "Hello world!";
| }
| }
|
Here is my HelloWorldRemote:
| package hi;
|
| import javax.ejb.Remote;
|
| @Remote
| public interface HelloWorldRemote {
| public String sayHi ();
| }
|
And then I get the Remote by this:
| Properties props = new Properties();
| props.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
| props.setProperty("java.naming.provider.url", new
String("jnp://localhost:1099"));
| props.setProperty("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
| InitialContext context = new InitialContext(props);
| hello = (HelloWorldRemote) context.lookup("HelloWorld");
|
I got the exception when i cast the object to HelloWorldRemote after lookup.
What is the problem with my code? How should I get the Remote correctly?
Please help. Thanks!!
Regards,
Candy
