I am not sure about this, but it looks like the container is

We definitely do do that. But we only do that as a fallback if we
can't find an already configured <Resource> that supplies the type you
need (in this case sample.jndi.ResourceBean). When webbaps boot, we
export all the Tomcat configured resources as OpenEJB <Resource>
objects so they are available for injection. What we don't do is log
a message when we do that which would be really handy right now.... at
least I don't think we do (maybe on debug?)
Theoretically if it was imported by OpenEJB it would show up under
java:openejb/Resource/. You might try listing that context and seeing
if it's there.
Here's a neat little chunk of code to help:
public static void contextToMap(Context context, String baseName,
Map<String,Object> results) throws NamingException {
NamingEnumeration<Binding> namingEnumeration =
context.listBindings("");
while (namingEnumeration.hasMoreElements()) {
Binding binding = namingEnumeration.nextElement();
String name = binding.getName();
String fullName = baseName + name;
Object object = binding.getObject();
results.put(fullName, object);
if (object instanceof Context) {
contextToMap((Context) object, fullName + "/",
results);
}
}
}
Hopefully I can poke at this Friday.

That definitely should work. Let me see if I can't reproduce this.

I can look it up successfully from a servlet like this
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
ResourceBean bean = (ResourceBean) envCtx.lookup("bean/
ParamsFactory");
The same look up fails when performed inside a session bean.
I tried to integrate the declarations in the openejb web module
web.xml
descriptor also but with no success.
If you can look it up from a Servlet, we're not too far! Post the
ejb-
jar.xml you using if you can. You would need an identical
resource-
env-ref in there for your session bean.
