This is really close, you just need to add the package part to the  
'provider' attribute.  So if you put it at META-INF/com.foo/service- 
jar.xml, the provider id would be "com.foo#myId".

That said, there might be a simpler way to do what you want overall.   
The service-jar.xml stuff is really geared towards plugging in  
something that needs to be configurable.  If you simply want an  
instance of a specific class injected you can create a property editor  
for it as described here:  http://openejb.apache.org/3.0/custom-injection.html 
.

Let us know if that helps.  Also, feel free to go into detail on the  
kind of thing you're looking to add to the system as we definitely use  
that feedback to drive features.  We've talked about enhancements to  
the service-jar.xml/openejb.xml functionality as well as specific  
enhancements for j2ee connector configuration and more.
