Unable to lookup resource on component level in Websphere

Question

At the moment I'm working on an application that has to use a connection factory. When I lookup the connection factory directly on a global level by the name set in WAS everything is working fine, but for means of decoupling I want to define a resource reference in my application and lookup that name. So I created following entry in my application.xml:

<resource-ref>
    <res-ref-name>jms/connectionFactory</res-ref-name>
    <res-type>javax.jms.ConnectionFactory</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

What I do then inside my EJB is making following lookup:

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

This leads to this exception:

javax.naming.NameNotFoundException: Name comp/env/jms not found in context "java:".

I also tried it with:

ConnectionFactory connectionFactory = 
(ConnectionFactory) ic.lookup("java:app/jms/connectionFactory");

leading to:

javax.naming.NameNotFoundException: Context: BPMDev/applications/com.ibm.ws.AppNameSpaces/MAN_POT/root,
name: jms/connectionFactory: First component in name jms/connectionFactory not found.

Does anyone know what I'm doing wrong here? Thanks in advance!

Answer 1

Further investigations brought me to: Lookup jndi resources WebSphere 8.5, Spring 3.1.3, Hibernate 4.1.10 EJB 3

There the answer is contained:

Both the entry in the application.xml and the lookup have to be preceeded with java:app/env. For my case this is:

<resource-ref>
    <res-ref-name>java:app/env/jms/connectionFactory</res-ref-name>
    <res-type>javax.jms.ConnectionFactory</res-type>
    <res-auth>Container</res-auth>
   <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

and:

ConnectionFactory connectionFactory = 
(ConnectionFactory) ic.lookup("java:app/env/jms/connectionFactory");
