I have problem with connecting to JBoss instance from standalone Java client.
I have this problem with JBoss 4.0.3 with JBoss 4.0.3RC2 all goes fine.
I've prepared some classes to replicate this problem.
session bean class:
| import javax.ejb.Remote;
| import javax.ejb.Stateless;
| @Stateless
| @Remote(HelloWorldRemote.class)
| public class HelloWorldBean implements HelloWorld{
| public String hello(String msg) {
| return "Hello " + msg + " world!";
| }
| }
|
interface classes:
| public interface HelloWorld {
| String hello(String msg);
| }
| ...
| import javax.ejb.Remote;
| @Remote
| public interface HelloWorldRemote extends HelloWorld{
|
| }
|
client class:
| import java.util.Properties;
| import javax.naming.Context;
| import javax.naming.InitialContext;
|
| public class HelloWorldClient implements HelloWorld{
|
| public String hello(String msg) {
| // TODO Auto-generated method stub
| return getDelegate().hello(msg);
| }
|
| private HelloWorld getDelegate() {
| try {
| InitialContext ctx1;
| Properties env = new Properties();
| env.setProperty(Context.INITIAL_CONTEXT_FACTORY,
|
"org.jboss.security.jndi.JndiLoginInitialContextFactory");
| env.setProperty(Context.SECURITY_PRINCIPAL, "guest");
| env.setProperty(Context.SECURITY_CREDENTIALS, "q");
| ctx1 = new InitialContext(env);
| return (HelloWorld)
ctx1.lookup(HelloWorldRemote.class.getName());
| } catch (Throwable e) {
| e.printStackTrace();
| System.exit(1);
| }
| return null;
|
| }
|
| public static void main(String[] args) {
| HelloWorld hello = new HelloWorldClient();
| System.out.println(hello.hello("JBoss4.0.3"));
| }
| }
|
I'am using JBoss all configuration prepared to use EJB3
All deploys fine, but when I run client I have to wait couple of second and I
can see following Exception on the server side:
| 15:18:35,786 ERROR [ServerThread] failed to process invocation.

What is wrong with the new JBoss?
Is that a bug or configuration issue.
What should I do to get it right?
