开发远程和本地接口的无状态会话bean
这个bean的开发，就是前面两个开发的综合，没有什么新东西。代码如下：
1、定义接口
远程接口：
package huizhi.HelloEJB3;
import javax.ejb.Remote;
@Remote
public interface HelloEJB3beanRemote {
public String remoteHello(String name);
}
本地接口：
package huizhi.HelloEJB3;
import javax.ejb.Local;
@Local
public interface HelloEJB3beanLocal {
public String localHello(String name);
}
2、完成实现类
package huizhi.HelloEJB3;
import javax.ejb.Stateless;
/**
* Session Bean implementation class HelloEJB3bean
*/
@Stateless
public class HelloEJB3bean implements HelloEJB3beanRemote, HelloEJB3beanLocal {
/**
* Default constructor.
*/
public HelloEJB3bean() {
// TODO Auto-generated constructor stub
}
public String localHello(String name){
return new String("本地接口：你好，" + name);
}
public String remoteHello(String name){
return new String("远程接口：你好，" + name);
}
}
3、测试的JSP页面
<%@ page language="java" import="javax.naming.*, huizhi.HelloEJB3.*" pageEncoding="GB2312"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB2312">
<title>无状态远程接口&本地接口调用</title>
</head>
<body>
<%
try{
InitialContext ctx = new InitialContext();
HelloEJB3beanLocal hrL = (HelloEJB3beanLocal)ctx.lookup("HelloEJB3bean/local");
out.println("<br>通过本地接口调用EJB<br>" + hrL.localHello("李小婉"));
HelloEJB3beanRemote hrR = (HelloEJB3beanRemote)ctx.lookup("HelloEJB3bean/remote");
out.println("<br><br>通过远程接口调用EJB<br>" + hrR.remoteHello("李小婉"));
}catch(Exception e){
out.println("调用失败！");
}
%>
</body>
</html>
在JBoss打包和发布，也和远程接口的会话bean那里说的一样。
