Use of local interface local on weblogic

First, let's have a general directory structure.

Code directly below

HelloWorld.java

package com.fhit.ejb;

public interface HelloWorld {
	public String say(String name);
}

HelloWorldLocal.java

package com.fhit.ejb;

public interface HelloWorldLocal extends HelloWorld{

}

HelloWorldBean.java

package com.fhit.ejb.impl;

import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;

import com.fhit.ejb.HelloWorld;
import com.fhit.ejb.HelloWorldLocal;

@Stateless(mappedName="HelloWorldBean")
@Remote(HelloWorld.class)
@Local(HelloWorldLocal.class)
public class HelloWorldBean implements HelloWorld,HelloWorldLocal{

	@Override
	public String say(String name) {
		// TODO Auto-generated method stub
		return name+"Hello";
	}

}

build.xml is the file that is deployed using ant, and the ant window will appear on the right side of eclipse-windows-show view-ant

Right-click the project name under ant, run as is ant build and the following appears to indicate success

Then enter the URL and the following will appear

If you want to test the remote interface remote that appears above, you can create a new java project test

import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import com.foshanshop.ejb3.HelloWorld;
public class Tclient {

	public static void main(String[] args) throws NamingException {
		 Properties properties=new Properties();  
	        properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");  
	        properties.setProperty(Context.PROVIDER_URL,"t3://localhost:7001");
	        Context context = new InitialContext(properties);  
	        HelloWorld hello = (HelloWorld) context.lookup("HelloWorldBean#com.fhit.ejb.HelloWorld");  
	        System.out.println(hello.say("Outlander"));
	}
}

The console output is
