This message is actually out of date now. There are also default
factories to create javax.mail.Session and
javax.mail.internet.MimePartDataSource as well.

If you don't mind specifying the resource factory class yourself, you
don't need to modify any code at all -- just configure it in server.xml
like this:
<Context path="/myapp" ... >
...
<Resource name="jndi/ContextPool"
type="com.mycompany.ContextPool"/>
<ResouceParams name="jndi/ContextPool">
<parameter>
<name>factory</name>
<value>com.mycompany.ContextPoolFactory</value>
</parameter>
<parameter><name>name</name><value>value</value></parameter>
...
</ResourceParams>
...
</Context>
where "com.mycompany.ContextPoolFactory" is a class that implements
javax.naming.spi.ObjectFactory. You can use the existing factories as
examples of how such factories can access the declared resource parameters
and use them to configure the object itself.
