JMS on Remote Machine

Question

i have a basic JMS application that runs fine
on my local machine. it also runs fine when
run locally on the server. however, when i try
to attach to the server from my local machine,
i have to add an 'env' block to my InitialContext:
Hashtable env = new Hashtable();
env.put
(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.Applicatio
nClientInitialContextFactory");
env.put(Context.PROVIDER_URL, "ormi://my.url.com:23791");
env.put(Context.SECURITY_PRINCIPAL, "uid");
env.put(Context.SECURITY_CREDENTIALS, "pwd");
i'm able to contact the remote machine, and authenticate,
but it is unable to find the JMS objects.
i can't use the (local) method call:
lookup("java:comp/env/jms/theTopicConnectionFactory")
because it throws a runtime exception:
java:comp/env namespace is only available from within a J2EE
component
if i use: lookup("jms/theTopicConnectionFactory")
i get a different runtime exception:
Error looking up objects: jms/theTopicConnectionFactory not found
again, this works just fine if i'm using a local server.
is this a JNDI issue, or something else?
after i've made a successful ormi connection,
how do i attach to a factory, and how do i
refer to a Topic (or Queue) on a remote server?
this is not documented well, and is driving me nuts.
thanks,
rich

Hi Rich,
Make sure that the connectionfactory topic names and locations are specified in the jms.xml file - also make sure you have given the host name and port name in the jms.xml your jms.xml should look like this. This should resolve the issue.
<jms-server port="9127" host="ipaddress">
     <!--     Queue bindings, these queues will be bound to their respective JNDI path for
          later retrieval -->
     <queue name="Demo Queue" location="jms/demoQueue">
          <description>A dummy queue</description>
     </queue>
     <!--     Topic bindings, these topic will be bound to their respective JNDI path for
          later retrieval -->
     <topic name="Demo Topic" location="jms/demoTopic">
          <description>A dummy topic</description>
     </topic>
     <topic name="The Topic" location="jms/theTopic">
          <description>A dummy topic</description>
     </topic>
     <topic-connection-factory name="The Topic Connection Factory" location="jms/theTopicConnectionFactory">
          <description>A dummy topic connection factory</description>
     </topic-connection-factory>
     <topic-connection-factory name=" Topic Connection Factory" location="jms/TopicConnectionFactory">
          <description>A dummy topic connection factory</description>
     </topic-connection-factory>     
     <!-- path to the log-file where JMS-events/errors are stored -->
     <log>
          <file path="../log/jms.log" />
     </log>
</jms-server>
