Docs\examples\ejb\simplemessage

[andrejt]

I work on the simplemessage MDB example (in Docs\examples\ejb\ from jbossj2ee-src.zip). Originally the SimpleMessage.ear contains mdb-app-client.jar and the code in the client is:

connectionFactory = (ConnectionFactory) jndiContext.lookup
 ("java:comp/env/jms/QueueConnectionFactory");

destination = (Queue) jndiContext.lookup("java:comp/env/jms/QueueName");

I want to separate the mdb-app-client.jar from SimpleMesage.ear part so that I can run them on different machines: MDB within the JBOSS 4.0 and the client on another machine without JBoss.
I have removed mdb-client-jar from the SimpleMessage.ear, changed
the lines:

connectionFactory = (ConnectionFactory) jndiContext.lookup("jms/QueueConnectionFactory");
destination = (Queue) jndiContext.lookup("avrisQueue");

and I got the following error message:

JNDI lookup failed: javax.naming.NameNotFoundException: jms not bound

What am I doing wrong?
Please help!?

Here are also my configuration files:

What is your JNDI conf. on your client?

[andrejt]

Here is my jndi.properties:

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming.client
j2ee.clientName=si.avris.prevoznik.SimpleMessageClient


But in the mean time I have the solution. Look to the previous client code:

connectionFactory = (ConnectionFactory) jndiContext.lookup("jms/QueueConnectionFactory");
destination = (Queue) jndiContext.lookup("avrisQueue");

The working version has queue/avrisQueue instead of avrisQueue:

connectionFactory = (ConnectionFactory) jndiContext.lookup("jms/QueueConnectionFactory");
destination = (Queue) jndiContext.lookup("queue/avrisQueue");

And now it works. I think my example (client running outside JBoss and MDB running within JBoss) is more common for real situations where one programmer works on client code while another one works on the EJB code.

I have one more question.
I have seen examples where people use jndi properties in different ways.
My setting is the default one (from Getting started example):

java.naming.provider.url=jnp://localhost:1099

Where on the JBoss is the port 1099 specified?

Hi there,

the JNDI Port (default 1099) is specified in your servers conf directory
in the file jboss-service.xml.
I had to change that due to conflicts with my virus protection software.
