I am trying to get started with EJB3 in JBoss. I have installed JBoss4.0.4GA
and patched in jboss-EJB-3.0_RC9-FD. Then I have written my first Stateless
Session Bean, derived from the training course, and (after some trouble)
deployed it.
I then try to access it with my Client, using the code below.
public static void main (String[] args) throws Exception
{
Properties props = new Properties () ;
props.setProperty ("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory") ;
props.setProperty ("java.naming.provider.url", "localhost:1099") ;
InitialContext ctx = new InitialContext (props) ;
Object o = ctx.lookup (CalcImpl.class.getSimpleName ()) ;
Calc calculator = (Calc) o ;
System.out.println ("1 + 1 = " + calculator.add (1, 1)) ;
System.out.println ("1 - 1 = " + calculator.subtract (1, 1)) ;
}
But the Object o returned from ctx.lookup is not, as I expect, a CalcImpl
Object, but a NamingContext Object, which then causes a Class Cast error.
What am I doing wrong?
Incidentally, after patching, the JBoss startup throws this exception:
... 83 more
11:42:02,648 ERROR [MainDeployer] Could not create deployment:

Should I worry? Should I report?
Thanks for any help
