Hi,
I'm starting with JBoss and having some problems with Message Driven Beans. I
have a Messenger class that put a message in a queue. It works normally.
package com.jboss.ejb.teste.message;
|
| import javax.jms.Connection;
| import javax.jms.Destination;
| import javax.jms.MessageProducer;
| import javax.jms.ObjectMessage;
| import javax.jms.QueueConnectionFactory;
| import javax.jms.Session;
| import javax.naming.InitialContext;
|
| public class Messenger {
|
| private QueueConnectionFactory connectionFactory;
| private Destination destination;
|
| public Messenger() {
| try {
| InitialContext ctx = new InitialContext();
|
| connectionFactory = (QueueConnectionFactory)
ctx.lookup("java:/ConnectionFactory");
| destination = (Destination)
ctx.lookup("queue/JBossTesteQueue");
| }
| catch (Exception exc) {
| exc.printStackTrace();
| }
| }
|
| public void sendMessage(String nome) {
| try {
| Connection connection =
connectionFactory.createQueueConnection();
| Session session = connection.createSession(true,
Session.AUTO_ACKNOWLEDGE);
|
| MessageProducer producer =
session.createProducer(destination);
|
| ObjectMessage message = session.createObjectMessage();
| message.setObject(nome);
|
| producer.send(message);
|
| session.close();
| connection.close();
|
| System.out.println("Mensagem enviada com sucesso!");
| }
| catch (Exception exc) {
| exc.printStackTrace();
| }
| }
|
| }
And have this MDB, but it doesn't run. I've already tried everything i could
but no success. No Exceptions, the deploy process is OK. It simply isn't called
by the JBoss when i put a messege in the queue.
package com.jboss.ejb.teste.message;
|
| import java.sql.Connection;
| import java.sql.DriverManager;
| import java.sql.PreparedStatement;
| import java.text.SimpleDateFormat;
| import java.util.Date;

| import javax.ejb.ActivationConfigProperty;
| import javax.ejb.MessageDriven;
| import javax.ejb.MessageDrivenContext;

| import javax.jms.MessageListener;
| import javax.jms.ObjectMessage;
|
| @MessageDriven(
| name = "MessageConsumer",
| activationConfig = {
| @ActivationConfigProperty(
| propertyName = "acknowledgeMode", propertyValue =
"Auto-acknowledge"),
| @ActivationConfigProperty(
| propertyName = "destinationType", propertyValue =
"javax.jms.Queue"),
| @ActivationConfigProperty(
| propertyName = "destination", propertyValue =
"queue/JBossTesteQueue")
| }
| )
| public class MessageConsumer implements MessageListener {
|
| @Resource
| private MessageDrivenContext context;
|
| public void onMessage(Message message) {
| try {
| ObjectMessage objectMessage = (ObjectMessage) message;
|
| String time = new SimpleDateFormat("dd/MM/yyyy -
HH:mm:ss").format(new Date());
| System.out.println("Mensagem recebida em " + time);
| System.out.println("Content: " +
objectMessage.getObject());
|
|
| Connection conn = null;
| PreparedStatement ps = null;
|
| try {
| Class.forName("com.mysql.jdbc.Driver");
| conn =
DriverManager.getConnection("jdbc:mysql://localhost/JBossEJBTeste", "root",
"admin");
|
| ps = conn.prepareStatement("insert into
teste_table (descricao) values ?");
| ps.setString(1, objectMessage.getObject() + " -
" + time);
|
| ps.execute();
| }
| catch (Exception exc) {
| exc.printStackTrace();
| }
| finally {
| try {
| ps.close();
| conn.close();
| }
| catch (Exception exc) {}
| }
|
| }
| catch (JMSException exc) {
| exc.printStackTrace();
| context.setRollbackOnly();
| }
| }
|
| }
