[JBoss-dev] JMS usability

[Stefan Puiu]

Hello,

I'm having real trouble here trying to make JBoss 3.0.4 compiled and run with JDK 1.4.0 send messages to a remote queue (on another computer). I've asked on the JBoss-user list and received no answer, so I'm trying here too. I heard somebody say he's using JBossMQ on production machines - maybe he can share this with us? We have purchased the JBoss manuals, but they aren't any good at explaining this.

Here is my original post:


Hello folks, I'm using JBoss 3.0.4 with the 1.4.0 JDK from Sun, compiled from sources, with jbossmq as the JMS implementation. I'm running everything on a Mandrake Linux 9.0. The remote computer uses the same versions of JBoss and JDK.

I'm trying to send a message to a queue on a different computer here; trouble is, I can't find the exact steps to take to do that in the docs. The approach I've been trying is using JNP to find the JNDI provider on the remote computer ("jnp://192.168.192.252:1099"), access the queue by it's name (say "queue/B"), and try to send it a message. But trouble is both lookup("ConnectionFactory") and lookup("queue/B") return null. When an office mate tries to send a message to me, the message gets through, but the JBoss console says something about an exception: "Cannot connect to the ConnectionReceiver/Server". I'm using localhost:8080/jmx-console to verify that messages get through. I'm trying to send messages from a client application, not from an enterprise bean.

Here's what I do:
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory"); env.put(Context.PROVIDER_URL, "jnp://merlin:1099");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
env.put( Context.SECURITY_PRINCIPAL, "john" );
env.put( Context.SECURITY_CREDENTIALS, "neddle" );
InitialContext iniCtx = new InitialContext(env);
System.out.println ("New context: " + iniCtx + " env: " + env);
QueueConnectionFactory qcf = (QueueConnectionFactory)
iniCtx.lookup("ConnectionFactory");
if (qcf == null) {
System.out.println ("OOPS");
//return ;
}

What am I doing wrong? Any ideas?
