Hello, I am getting an odd naming exception when I try to lookup the
connection factory:
<snip>
javax.naming.NameNotFoundException: QueueConnectionFactory not bound
at org.jnp.server.NamingServer.getBinding(NamingServer.java:474)
at org.jnp.server.NamingServer.getBinding(NamingServer.java:482)
at org.jnp.server.NamingServer.getObject(NamingServer.java:488)
at org.jnp.server.NamingServer.lookup(NamingServer.java:283)
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:295)

at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:367)
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:279)
<snip-truncate/>
</snip>
Here are the bits that I added to the ejb-jar and jboss xml files, as well
as a bit of the JNDIView output from the server this is running in:
<snip from="ejb-jar">
<resource-ref>
<description>Default QueueConnectionFactory</description>
<res-ref-name>jms/QueueConnectionFactory</res-ref-name>
<res-type>javax.jms.QueueConnectionFactory</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</snip>
<snip from="jboss">
<resource-ref>
<res-ref-name>jms/QueueConnectionFactory</res-ref-name>
<resource-name>QueueConnectionFactory</resource-name>
</resource-ref>
<snip-truncate/>
<resource-managers>
<resource-manager res-class="">
<res-name>QueueConnectionFactory</res-name>
<res-jndi-name>QueueConnectionFactory</res-jndi-name>
</resource-manager>
</resource-managers>
</snip>
<snip from="JNDIView Output">
+- QueueConnectionFactory (class: org.jbossmq.SpyQueueConnectionFactory)
</snip>
--
It looks like the namespace of the bean is ok:
<snip from="JNDIView Output">
+- env (class: org.jnp.interfaces.NamingContext)
| +- jms (class: org.jnp.interfaces.NamingContext)
| | +- QueueConnectionFactory (class: javax.naming.LinkRef)
</snip>
--
To lookup the object I am first getting the env context:
context = new InitialContext().lookup("java:comp/env/");
...
factory = (...) context.lookup("jms/QueueConnectionFactory");
--
I am not really sure where the naming problem comes up. It looks like it
might be having touble with the LinkRef, but that is only a guess since the
name I am looking for has a 'jms/' prefix on it at the bean level, but the
resource does not.
I will play around with it some more, but if you (or anyone else) has any
ideas please let me know.
Thanks,
--jason
