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

it crashes at deploy time like this:

Here it is what I've been trying:

1)Resource Factory configuration in tomcat context.xml

<Resource
     name="bean/ParamsFactory"
     auth="Container"
     type="sample.jndi.ResourceBean"
     factory="sample.jndi.GenericObjectFactory"
                value="ContextResource"
     />

2)test web application's  web.xml

<resource-env-ref>
<description>
  Object factory for ResourceBean instances.
</description>
<resource-env-ref-name>
   bean/ParamsFactory
</resource-env-ref-name>
<resource-env-ref-type>
  sample.jndi.ResourceBean
</resource-env-ref-type>
</resource-env-ref>


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.
