Re: "Could not auto-map to resource" problem when using EJB
annotations only
hi frank
This should be add to the application.xml(not geronimo-application.xml), coz
it is NOT Geronimo specific. It is the JEE specific.
<resource-ref>
<res-ref-name>jdbc/__mes</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

Hi Rex,
thanks a lot for your work and help. This works great! So I'm simply able to
define it in the geronimo-application.xml. Now I'm able to deploy the same
EAR in different application server implementations - great! I didn't find
this hint in the Geronimo documentation.
Thanks and Greetings,
Frank:jumping:

I think you should be able to avoid geronimo plans for each module.
You need to
1. make sure that the name specified in the annotations or dd resource-
ref is the same as the datasource name you specify when you deploy the
connection pool.
2. make the connection pool "visible" to your application by adding
its id as a dependency to the geronimo plan for your application.
This should be enough to make the auto-map work.
hope this helps

Hi Rex,
thanks for your answer. But this, I think, is the problem. My EAR consits
out of 40 EJB's and 25 WAR's and all are using the @Resource injection for
the database. Til now I don't have descriptors for the EJB's (no
"ejb-jar.xml") - I thought they are no longer neccessary in JEE5. And the
deployment descriptors of the WAR's ("web.xml") only contains the
servlet-mappings. (This EAR file can successfully deployed in JBoss and in
GlassFish without modifications.)
To be able to deploy this in Geronimo do I really need to add 40 new
"openejb-jar.xml", 40 new "ejb-jar.xml" and 25 new "geronimo-web.xml" files
- and also change 25 "web.xml" files to place the <resource-ref> tag? Is
there no way to just use injection without specifying it in all descriptors?
Maybe there is a way to define a jdbc resource globally in Geronimo to use
in with injection?
Thanks,
Frank

Hi Frank, sorry for the confusing, it can not be added to the
application.xml, but should be added to the web.xml / ejb-jar.xml...
here is an example in attachment.

Hi Rex,
thanks for the answer. But when I add this to the "application.xml" I get an
error, that this element is not allowed here. After looking to the
http://java.sun.com/xml/ns/javaee/application_5.xsd I couldn't find any hint
about the <resource-ref> tag inside the application.xml.
I couldn't find any hint about the <resource-ref> inside an application.xml
even not in the JaveEE5 specification.
Have you tried this?
Thanks,
Frank
