Dear JBoss-Comunity!
The Problem:
I wrote a simple Message Driven Bean and want to send her a Message!
The client program, which should send the message gets always the following Exception:
javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException:
org.jboss.jms.client.JBossConnectionFactory (no security manager: RMI class loader
disabled)]

My configuration:
I use JBoss AS 4.0.4 and installed the JBoss Messaging plugin (Version 1.0.1 GA)
The Deployment:
The MDB is correct deployed by JBoss (i use a JAR file which contains the bean).
I tried a lof of things, but nothing helped:
- Tried to use a SecurityManager
- Tried to use an ear file with the following jboss-app.xml file:
<jboss-app>
<loader-repository>
jboss.messaging:loader=ScopedLoaderRepository
<loader-repository-config>java2ParentDelegation=false</loader-repository-config>
</loader-repository>
</jboss-app>
The Code for the Message Driven Bean looks like:
import javax.jms.Message;
| import javax.ejb.ActivationConfigProperty;
| import javax.ejb.MessageDriven;
| import javax.annotation.*;
| import javax.jms.*;
|
| @MessageDriven(
| activationConfig = {
| @ActivationConfigProperty(propertyName = "destinationType",
| propertyValue = "javax.jms.Topic"),
| @ActivationConfigProperty(propertyName = "destination",
| propertyValue = "testTopic"),
| @ActivationConfigProperty(propertyName = "acknowledgeMode",
| propertyValue = "Auto-acknowledge")
|
| }
| )
| public class LogBean implements MessageListener
| {
| /*
| @Resource(mappedName="ConnectionFactory")
| private ConnectionFactory connectionFactory;
| */
|
| public LogBean()
| {
| System.out.println("LogBean created ...");
| }
|
| public void onMessage(Message msg) {
| if (msg instanceof TextMessage)
| {
| TextMessage tm = (TextMessage)msg;
| try
| {
| String text = tm.getText();
| System.out.println("Received new message: " + text);
|
| }
| catch (JMSException e)
| {
| e.printStackTrace();
| }
| }
| }
|
| @PreDestroy
| public void remove()
| {
| System.out.println("LogBean destroyed!");
| }
| }
|
The Code for the Client looks like:
| import java.rmi.RMISecurityManager;
| import java.util.Properties;
|
| import javax.annotation.*;
| import javax.jms.Topic;
| import javax.jms.ConnectionFactory;
| import javax.jms.Connection;
| import javax.jms.MessageProducer;
| import javax.jms.Session;
| import javax.jms.TextMessage;
| import javax.jms.JMSException;
| import javax.jms.TopicConnectionFactory;
| import javax.naming.Context;
| import javax.naming.InitialContext;
|
| public class Client
| {
| @Resource(mappedName = "testTopic")
| private static Topic topic;
|
| public static void main(String args[])
| {
| Connection connection = null;
| Session session = null;
| MessageProducer messageProducer = null;
| TextMessage message = null;
| final int NUM_MSGS = 3;
|
| try
| {
| InitialContext ctx = new InitialContext();
| if (ctx == null)
| {
| System.out.println("Kein gültiger Kontext!");
| System.exit(1);
| } else
| {
| System.out.println("Kontext gefunden (" + ctx.toString() +
")!");
| }
| TopicConnectionFactory factory =
(TopicConnectionFactory)ctx.lookup("/ConnectionFactory");
|
| // Connection factory benutzen, um eine JMS Connection zu erzeugen
| connection = factory.createConnection();
|
| // Connection benutzen, um eine Session zu erzeugen
| session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
|
| // Sender für einen Topic erzeugen
| messageProducer = session.createProducer(topic);
|
| // Nachricht, die gesendet werden soll erzeugen
| message = session.createTextMessage();
|
| for (int i = 0; i < NUM_MSGS; i++)
| {
| message.setText("This is message " + (i + 1));
| System.out.println("Sending message: " +
message.getText());
| messageProducer.send(message);
| }
| }
| catch (Exception e)
| {
| e.printStackTrace();
| }
| finally
| {
| if (connection != null)
| {
| try
| {
| connection.close();
| }
| catch (JMSException e)
| {
| }
| }
| } // finally
| } // main
| } // class
|
Need urgent help, because i need this bean to work ahaed on my current project @work.
Thank you very much!
Best regards
Björn Wilken
