Question

Right now I’m getting this exception from a simple JMS client I wrote to just test to see if I can connect to the JBoss JMS. Here is the snippet of my code below:

        Properties props = new Properties();
  props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
  props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");
  props.setProperty("java.naming.provider.url", url_);

  Context context = new InitialContext(props);
  System.out.println("performing lookup...");

  Object tmp = context.lookup("/ConnectionFactory");
  System.out.println("lookup completed, making topic");

  TopicConnectionFactory tcf = (TopicConnectionFactory) tmp;
  conn = tcf.createTopicConnection();
  topic = (Topic) context.lookup(name_);

  session = conn.createTopicSession(false, TopicSession.AUTO_ACKNOWLEDGE);
  conn.start();

  TopicSubscriber recv = session.createSubscriber(topic);
  recv.setMessageListener(this);

I have the following jars:
jms.jar (I got this from outside the JBoss distro)
jbossall-client.jar
log4j.jar
jboss-logging.jar
javax.jms.jar (I got this from outside the JBoss distro)
jnpserver.jar
jboss-common-core.jar

I get the following exception:

javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling return; nested exception is: 
 java.lang.ClassNotFoundException: org.hornetq.jms.referenceable.SerializableObjectRefAddr (no security manager: RMI class loader disabled)]

This is being run locally, also it seems it’s connecting to the JBoss server just that it’s throwing this exception.

Answer 1

To anybody interested I was able to solve this by adding a few more jar files to my classpath. Also the problem was that I didn’t have a security manager in place.

hornetq-jms.jar
hornetq-logging.jar
hornetq-bootstrap.jar
hornetq-core.jar
hornetq-jboss-as-integration.jar
jboss-as-hornetq-int.jar
netty.jar

This jar files can be found with the JBoss distribution.
