从helloworld开始吧,把下面的源文件编译一下，然后HelloWorld,HelloWorldBean打成jar包，copy到jboss运行环境下，运行Test就可以了,教程直接去百度找
HelloWorld.java
public interface HelloWorld {
public String SayHello(String name);
}

HelloWorldBean.java
import javax.ejb.Remote;
import javax.ejb.Stateless;

@Stateless
@Remote( { HelloWorld.class })
public class HelloWorldBean implements HelloWorld {
public String SayHello(String name) {
// TODO Auto-generated method stub
return name + "说：你好!这是我的第一个EJB3 哦.";
}
}
Test.java
import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class Test {

public static void main(String[] args) {
// TODO Auto-generated method stub
Properties props = new Properties();
props.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
props.setProperty("java.naming.provider.url", "localhost:1099");
props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");
//InitialContext ctx;

Context ctx;
try {
ctx = new InitialContext(props);
HelloWorld helloworld = (HelloWorld) ctx.lookup("HelloWorldBean/remote");
System.out.println(helloworld.SayHello("Test"));
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
