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.
I didn't do anything like this before in Tomcat or any EJB container but it
looks to me like a clean and portable solution for loading application
configuration parameters which happen to be in xml format.
