JNDI access to java:/Mail from MDB

bruth Mar 30, 2004 2:49 PM

I'm trying to access the JavaMail provider I've configured in mail-service.xml, under java:/Mail. If I lookup "java:/Mail" in my MDB, all works fine.

However, if I try to access "java:/comp/env/mail/MailProvider" - as I believe I've configured ejb-jar.xml and jboss.xml, then I get Naming exceptions indicating that "mail" is not bound, so obviously - my JNDI configuration in ejb-jar and jboss.xml is NOT correct.

Here's what I have:

ejb-jar.xml:

<resource-ref >
 <res-ref-name>mail/MailProvider</res-ref-name>
 <res-type>javax.mail.Session</res-type>
 <res-auth>Container</res-auth>
 </resource-ref>

jboss.xml:

<resource-ref>
 <res-ref-name>mail/MailProvider</res-ref-name>
 <jndi-name>java:/Mail</jndi-name>
 </resource-ref>

These are auto-generated by XDoclet via the following tags:

* @jboss.resource-ref
* res-ref-name = "mail/MailProvider"
* jndi-name = "java:/Mail"
* @ejb.resource-ref
* res-ref-name = "mail/MailProvider"
* res-type = "javax.mail.Session"
* res-auth = "Container"

I'm a bit at a loss here ... what's going on? jBoss 3.2.3 on WinXP.

TIA

Have you had a look at the JNDI view in the JMX console?

I have now ... :)

Under my Ejb Module (JMS Dev.jar), all I see is this:

java:comp namespace of the MessageWriterEJB bean: +- env (class: org.jnp.interfaces.NamingContext)

The only reference to "mail" anything that appear on the JNDIView page is the entry for java:/Mail.

Should I be looking at something else? Is there something wrong with the way I've setup my ejb-jar.xml or jboss.xml?

Any help at all is much appreciated!!

There there is something wrong with your deployment or descriptors if there is nothing under the JNDIView. The descriptors should look like: <a href="

4. Re: JNDI access to java:/Mail from MDB

bruth Apr 6, 2004 9:41 AM (in response to bruth)

OK, I'm still not seeing anything. In jboss.xml, in the <resource-ref>...</resource-ref> for my MDB, what is the resource-name supposed to refer to? If the JNDIName I've defined for mail-service.xml is java:/Mail, is resource-name supposed to be 'Mail' or java:/Mail, or something else?

Also, in JNDIView, am I supposed to see these entries under the java:comp namespace of my EJB? That would be my assumption ... Right now, all I see listed for my EJB is 'env' -

java:comp namespace of the MessageWriterEJB bean:

 +- env (class: org.jnp.interfaces.NamingContext)

I very much appreciate any and all help in getting to the bottom of this ... and many thanks for being patient with a newbie!

Here's what I have now:

jboss.xml:

 <resource-name>Mail</resource-name>
 </resource-ref>

</jboss>

Shouldnt this be java:comp/env/mail/MailProvider?
or is this a typo?

I can give this a shot, but since I'm not seeing anything in JNDIView for "MailProvider" - I'm not sure if it'll make a difference!! It seems like something's still wrong with my ejb-jar.xml and/or jboss.xml.
