Hi.
First of all, I'm using JBoss 4.0.1 and Eclipse 3.0.1M6 with MyEclipse.
I've deployed a Stateless Session Bean in the server and it's ok. In fact, when
I see the jmx-console in the JNDI view I can see the values for the EJB
deployed.
The issue is that when I try to access the EJB through a client (in my case a
JUnit Test Case class, but also I've tried with a standalone application),
always I get a ClassCastException.
The method of the client code I'm calling is:
| public void testClientEJB(){
| Properties props = new Properties();
| props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| props.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
| props.put(Context.PROVIDER_URL, "localhost:3332");
| try{
| InitialContext ctx = new InitialContext(props);
| assertTrue(ctx!=null);
| Object ref = ctx.lookup("ejb/HelloWorld");
| System.out.println("Got a reference to the EJB");
| HelloWorldHome pruebaHome = (HelloWorldHome)
PortableRemoteObject.narrow(ref,HelloWorldHome.class);
| assertTrue(pruebaHome!=null);
| HelloWorld pruebaServer = (HelloWorld) pruebaHome.create();
| System.out.println(pruebaServer.execute());
| }catch (Exception e){
| e.printStackTrace();
| }
| }
|
And the console output is:
| Got a reference to the EJB
| java.lang.ClassCastException

org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:194)
|
Note: The line 29 in testClient is when I try to obtain the Remote Interface
from the create method of the home interface,i.e.,
| HelloWorld pruebaServer = (HelloWorld) pruebaHome.create();
|
Of course, I have in the classpath client the jbossall-client.jar
I've had the Eclipse EJB Project linked as a Project required on the build path
(to make the interfaces classes available to the application) and the error was
there.
I've tried to export a jar with the classes of the EJB and include this jar in
the classpath of the application and the error continued there.
Someone has experienced this kind of error?
Thanks a lot
