[jboss-user] [JBoss Messaging] - NoClassDefFound Exception connecting to JBM 1.4.0

[dkuanwang]

Hi, 

I am writing a standalone java client to connect to JBM 1.4.0 queue.

Following is my code:

Properties p = new Properties();
            p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
            p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming: org.jnp.interfaces");
            p.put(Context.PROVIDER_URL, "jnp://host:port");

            Context jndiContext = new InitialContext(p);
                       
            //get reference to the ConnectionFactory
            ConnectionFactory connectionFactory =
                    (ConnectionFactory) jndiContext.lookup("ClusteredConnectionFactory");
            
            //get reference to JMS destination
            javax.jms.Queue destination =
                    (javax.jms.Queue) jndiContext.lookup("queue/queue1");
            
            Connection connection = connectionFactory.createConnection("user","pwd");

I am getting exception at the createConnection:

I have included the jbossall-client.jar in the classpath so I am not sure why it's getting class definition not found exception.

My classpath is as followed:
jboss-aop.jar
jboss-remoting.jar
javassist.jar
trove.jar
jbossall-client.jar
jboss-mdr.jar

Can someone also explain how the JBM class loading works with AOP , jboss-remoting.jar and jbossall-client.jar? 

thanks in advance,
David
