That's quite alright. Thinking out loud is "documenting out loud" and all sorts of good things can come from that.
On the question of why your connector shows up as "classes", it's because we use the jar or directory name to come up with the module name and we use the module name as the name of the connector. You can set the name of the connector in the ra.xml like so: 

  <connector id="FooConnector">
    ...
  </connector>
Not all vendors will use that id, but we do. In Java EE 6 all descriptors will have a "<module-name>" element where the name can be standardly set, which will be very nice.
Did you figure out how to get references to your objects from JNDI? From inside an EJB or Servlet you can use @Resource to get it bound into java:comp/env and made available for lookup or injection. 

Hope that helps!  Keep sending the emails :)

Heya

I think I got a bit further, but still am confused.

OpenEJB in its Assembler::createResource() method does create both an
instance of my  ResourceAdapter and an instance of my
ManagedConnectionFactory. Both instances are bound to JNDI through (also 
from Assembler::createResource()):

containerSystem.getJNDIContext().bind("openejb/Resource/" +
serviceInfo.id, service);
Strange enough the serviceInfo.id is 'classesRA' for the ResourceAdapter and 'classes' for the ManagedConnectionFactory, respectively (see log, below). Is this normal or am I missing something in my implementation ? 

Further, when I try to lookup either "openejb/Resource/classesRA" or
"openejb/Resource/classes", I get an NameNotFoundException. How can I get 
a reference to the ManagedConnectionFactory object through the
initialContext ?
        
Any help is very much appreciated, Christian.

Heya
I am implementing an outbound-resourceadapter. The RAR seems to deploy fine, but the ManagedConnectionFactory's createConnectionFactory method 
is never triggered by the container.
As I learned every application server has some complement to the ra.xml. 
In JBoss for example there are the *-ds.xml files as mentioned in an
http://old.nabble.com/Re%3A-Unit-testing-code-containing-DirContext-resource-injection-p24836874.html
earlier post . In such *-ds.xml files, for example the JNDI name of the 
instantiated ConnectionFactory object is given.

Instantiation of the ConnectionFactory object (the call to the
ManagedConnectionFactory's createConnectionFactory method) and binding to 
JNDI registry is triggered by JBoss at *-ds.xml file processing.

I want to accomplish the same with OpenEJB. I found an ra.xml
complementing http://cwiki.apache.org/GMOxDOC22/geronimo- raxml.html file for Geronimo, but see no JNDI name declaration in there and don't know 
how to apply it for OpenEJB.
How does one configure matter for OpenEJB ? How to trigger the creation of a ManagedConnectionFactory, the instantiation of the ConnectionFactory 
object and the binding of the latter to JNDI ?

Any help very much appreciated, cheers, Christian.
