Calling JBossMQ standalone from JBoss+TC

[mlecza]

Is it possible to Publish a message from a servlet running on JBoss+TC 2.4 final onto JBossMQ running standalone?

I can publich a message just fine from a Servlet to JBossMQ integrated with 2.4 - but from what I have been reading the new version of JBossMQ is clearly what I should be using.

Yes you can.. You just have to JNDI setup ok.
You have serveral options:

a. You can have JBossMQ bind itself to the JBoss/TC naming server. Just modify the jndi.properties file in the JBossMQ conf directory to specify the URL. Disable the Naming server MBean in the JBossMQ conf directory.

b. You can runn another Naming Server instance in JBossMQ standalone. (You may get port conflicts if a naming server is allready running on the same machine.) From the servlet you will need to explicitly initialize the IntialContext with a URL pointing to the server:port were the JBossMQ standalone naming server is running.

Thanx for the reply.

I tried option b and am getting the following error:

[Default] javax.naming.CommunicationException [Root exception is java.rmi.Unmars
halException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: org.jboss.mq.referenceable.ObjectRefAd
dr (no security manager: RMI class loader disabled)]

any ideas?

This is how I did the InitialContext in the servlet:
Hashtable props = new Hashtable();
props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
props.put(Context.PROVIDER_URL, "localhost:1088");
props.put("java.naming.rmi.security.manager", "yes");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

Context context = new InitialContext(props);

JNDI is running fine in the JBOssMQ instance on port 1088

Thanx

... and same type of message when I tried option A - this error happens when starting JBossMQ:

java.lang.ClassNotFoundException: org.jboss.mq.referenceable.ObjectRefAddr

Make sure you have jbossmq-client.jar in your classpath.

[mlecza]

That's not the problem.

Pretty sure the problem has somethign to do with this part of the error:
(no security manager: RMI class loader disabled)

[mlecza]

Got it to work both ways - I needed to take a copy of jbossmq.jar from the beta install and put it in the JBoss2.4+TC area :-))

Thanx for the replies.

This means the same thing. The RMI subsystem can't find the classes in your classpath, and since no security manager is installed, can't download the classes it needs either.

So yes, it is the problem.

[mlecza]

yeah - I had the old jbossmq.jar that comes with 2.4 in the JB+TC area - guess either there were missing classes or conflicts.

Thanx for the reply
