您当前的位置: 服务端（test）：
HelloWorld接口：
- Java code
package com.test.ejb3;
public interface HelloWorld {
public String SayHello(String name);
}
HelloWorldBean接口实现类：
- Java code
package com.test.ejb3.impl;
import com.test.ejb3.HelloWorld;
import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;
@Stateless
@Remote (HelloWorld.class)
@Local (HelloWorld.class)
public class HelloWorldBean implements HelloWorld {
public String SayHello(String name) {
return name+":Hello~~!";
}
}
客户端（web）：
EJBFactory你懂的：
- Java code
package com.web.util;
import java.util.Properties;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class EJBFactory {
public static Object getEJB(String jndipath) {
try {
Properties props = new Properties();
props.setProperty("javax.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
props.setProperty("javax.naming.provider.url", "jnp://127.0.0.1:1099");
props.setProperty("javax.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
props.setProperty("jnp.disableDiscovery", "true");
InitialContext ctx = new InitialContext(props);
return ctx.lookup(jndipath);
} catch (NamingException e) {
e.printStackTrace();
}
return null;
}
}
index.jsp调用页面:
- Java code
<%@ page contentType="text/html; charset=GBK"%>
<%@ page import="com.test.ejb3.HelloWorld,com.web.util.EJBFactory;"%>
<%
HelloWorld helloWorld = (HelloWorld) EJBFactory.getEJB("HelloWorldBean/remote");
out.println(helloWorld.SayHello("Good")+"<br/>");
%>
在浏览器中打开index.js
出现错误：
- Java code
javax.naming.NameNotFoundException: Name HelloWorldBean is not bound in this Context
我把EJBFactory 的代码改为：
- Java code
props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
props.setProperty("java.naming.provider.url", "jnp://127.0.0.1:1099");
props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
在浏览器中打开index.js
出现错误：
- Java code
javax.naming.CommunicationException: Could not obtain connection to any of these urls: 127.0.0.1:1099 [Root exception is javax.naming.CommunicationException: Failed to connect to server 127.0.0.1:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server 127.0.0.1:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]]
