随笔:一个单独的JMS例程

来源：互联网发布：图片特效制作软件编辑：程序博客网时间：2024/05/16 01:33

开发工具:WebSphere Integration Developer 6.1(WID)

中间件服务器: WebSphere Process Server (WPS)

1. 在wid中创建一J2EE工程,加入一个动态web项目

2.创建index.jsp,内容如下:

<%@ page language="java" contentType="text/html; charset=GB18030"
    pageEncoding="GB18030"%>
    <%@ page import="javax.jms.*" %>
    <%@ page import="javax.naming.*" %>
<!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=GB18030">
<title>Insert title here</title>
</head>
<body>
<%

try
{

   final InitialContext context = new InitialContext();
   //final InitialContext context = new InitialContext(props);
   // Lookup the queue connection factory from the
   // initial context.

    final QueueConnectionFactory qcf = (QueueConnectionFactory) context.lookup("ladqcf");

    System.out.println("the qcf is "+qcf);
   // Create a new queue connection from the queue
   // connection factory.
    final QueueConnection conn = qcf.createQueueConnection();
    System.out.println("the conn is "+conn);
   // Start the connection
   conn.start();
   // Create a new queue session from the queue
   // connection. The session should not be transacted
   // and should use automatic message acknowledgement.
    final QueueSession qsession = conn.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);

   // Lookup the queue to be used to send and receive
   // messages from the initial context.
    final Queue q = (Queue) context.lookup("ladq");

   // Create a new queue sender using the queue session.
   // The sender should be created to send messages to
   // the queue q.
    final QueueSender sender = qsession.createSender(q);

   // Create a text message using the queue session.
   // Initialize the message's data to a String of your
   // choice.
    final TextMessage sentMessage = qsession.createTextMessage("My first JMS message.");
    System.out.println("sending message : "+sentMessage.getText());

   // Send the sentMessage object using the queue sender.
    sender.send(sentMessage);
    System.out.println("sent message : "+sentMessage.getText());
   // Create a new queue receiver using the queue session.
   // The queue receiver should be created to receive
   // messages from the queue q.
    final QueueReceiver receiver = qsession.createReceiver(q);

   // Use the queue receiver to receive the message that
   // was sent previously.
    final Message receivedMessage = receiver.receiveNoWait();

   // Output the received message to System.out
   if(receivedMessage!=null)
    {
    System.out.println("Received Message is : "+((TextMessage)receivedMessage).getText());
    }else{
    System.err.println("Received nothing................");
    }
  }
  catch (NamingException ne)
  {
   ne.printStackTrace();
  }
  catch (JMSException jmse)
  {
   System.err.println("error................");
   Exception linkedException = jmse.getLinkedException();

   if (linkedException != null)
   {
    linkedException.printStackTrace();
   }

   jmse.printStackTrace();
  }
   %>
</body>
</html>

3.在WPS中配置JMS资源.

a.创建BUS.登陆WPS,"Service integration"->"Buses"->"New",只要BUS的名字即可

b.添加Bus member,"Service integration"->"Buses",点击刚建立的Bus,在"Topology "下点击"Bus members",进入"Bus members"页面,点击"Add"按钮. step1, 选择server项; step2,选择filestore; step3 默认; step4 finish. 保存配置.

c.创建Destinations. ,"Service integration"->"Buses",点击刚建立的Bus,"Destination resources"->"Destinations",

已经存在两个默认的destination, 再建立一个,点击"New" 按钮,选择类型,默认为Queue,输入Identifier ,选择所属于的Bus Member,下一步,保存.

d.创建Queue connection factory. "Resources"->"jms"->"Queue connection factory",点击"New"按钮,选择"Default messaging provider",OK进入下一页面,输入name,JNDI name填ladqcf,bus member选择刚创建的bus,其他默认,保存.

e.创建Queue."Resources"->"jms"->"Queues",点击"New"按钮,选择"Default messaging provider",OK进入下一页面,输入name,JNDI name填ladq,bus member选择刚创建的bus,Queue name选c步创建的destination,其他默认,保存.

JMS资源配置完毕.访问页面,可以看到输出.
