ActiveMQ Connection with TomEE JNDI

 

 1. Create Dynamic Web Project in Eclipse 

2. Use below configuration in Tomee.xml in conf:

 <Resource id="amqRA" type="ActiveMQResourceAdapter">
      BrokerXmlConfig = broker:(tcp://localhost:61616)?useJmx=false
      ServerUrl = vm://localhost
      StartupTimeout = 10 seconds
  </Resource>

 
  <Resource id="amqCF" type="jakarta.jms.ConnectionFactory">
      ResourceAdapter = amqRA
      TransactionSupport = xa
      PoolMaxSize = 10
      PoolMinSize = 0
      ConnectionMaxWaitTime = 5 seconds
      ConnectionMaxIdleTime = 15 Minutes
  </Resource>

3. Java Lookup code in Servlet:

package com.teg;

import java.io.IOException;
import java.io.PrintWriter;

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

import jakarta.jms.Connection;
import jakarta.jms.ConnectionFactory;
import jakarta.jms.JMSException;
import jakarta.servlet.ServletConfig;
import jakarta.servlet.ServletException;
import jakarta.servlet.http.HttpServlet;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;


/**
 * Servlet implementation class JndiTest
 */
public class JndiTest extends HttpServlet {
    private static final long serialVersionUID = 1L;
    private ConnectionFactory cf = null;
    /**
     * Default constructor.
     */
    public JndiTest() {
        // TODO Auto-generated constructor stub
    }

    /**
     * @see Servlet#init(ServletConfig)
     */
    public void init(ServletConfig config) throws ServletException {
        System.out.println("Application Deployed in TomEE");
        try {
            InitialContext initContext = new InitialContext();
            ConnectionFactory cf = (ConnectionFactory)
                    initContext.lookup("openejb:Resource/amqCF");
            System.out.println("Connection Factory::  " + cf);
            Connection connection = cf.createConnection();
            connection.start();
            System.out.println("Connection can be tried here");
            connection.close();
        } catch (NamingException | JMSException e) {
            System.out.println(e);
            e.printStackTrace();
        }
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        PrintWriter out = response.getWriter();
        out.println("Served at: doGet");
        try {
            Connection connection = cf.createConnection();
            connection.start();
            out.println("Connection can be tried here");
            connection.close();
        } catch (JMSException e) {
            out.println(e);
            e.printStackTrace();
        }
        out.println("Serviced at: doGet");
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        doGet(request, response);
    }

}

4. Export WAR file in Put it in Tomee Webapps folder

- Please delete existing wars, folders in Webapps and Work folder before running new project.
