[jboss-user] [JBoss Messaging] - NoClassDefFound Exception connecting to JBM 1.4.0
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:
Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize

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
