Remote JNDI-Lookup on JBoss 7.1 - Failed to connect to remote host
Hi, I'm quite new to JavaEE and trying to get a little EJB example running, but always fail with the remote JNDI-Lookup.
What did I do until now?
- I use Eclipse for JavaEE, installed JBossTools ffrom the Marketplace and created a JBoss EAP 7.x Runtime Server (I downloaded a 7.1 runtime during setup).
- I wrote some Beans, deployed them on the server and started it.
- I wrote some client code with a JNDI-Lookup
Here is all relevant code:
// HelloWorld.java
package com.ibytecode.business;
import javax.ejb.Remote;
@Remote
public interface HelloWorld {
public String sayHello();
}
// HelloWorldBean.java
package com.ibytecode.businesslogic;
import com.ibytecode.business.HelloWorld;
import javax.ejb.Stateless;
/**
* Session Bean implementation class HelloWorldBean
*/
@Stateless
public class HelloWorldBean implements HelloWorld {
public HelloWorldBean() { }
@Override
public String sayHello() {
return "Hello World !!!!!";
}
}
// EJBApplicationClient.java
package com.ibytecode.client;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.ibytecode.business.HelloWorld;
public class EJBApplicationClient {
public static void main(String[] args) {
try {
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, org.wildfly.naming.client.WildFlyInitialContextFactory.class.getName());
env.put(Context.PROVIDER_URL, "remote://localhost:4447");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "admin");
InitialContext ic = new InitialContext(env);
ic.lookup("java:global/HelloWorldSessionBean/HelloWorldBean");
} catch (NamingException e) {
e.printStackTrace();
}
}
}
Part of the pom.xml
org.wildfly wildfly-ejb-client-bom 16.0.0.Final pom org.wildfly wildfly-jms-client-bom 16.0.0.Final pom

So, I think the deployment of the bean and the Lookup-Name should be correct. But when I run the client application, I get this output:

I guess I am just missing some simple configuration.
Any help is highly appreciated! Thanks!
