4. add objects to inject resources
Here's where I get confused. Add objects to inject resources
into what? The confusing part is that injection is done on
instances of components (servlets, ejbs). Maybe the Tomcat/Jetty
integrations are a lot tighter than I thought they were. Are we
actually creating servlet and filter instances themselves?
Definitely not for tomcat. For jetty these are created by a
ServletHolder, which is wrapped into a gbean, so we could modify
the object creation code. I imagine there's some similar way to
customize tomcat, but I have no idea what it might be.
In any case, my goal of using verbiage sufficiently general to be
difficult to argue with failed :-). I have no idea what is
needed nor how to do this. Do you have any advice?
:)
I have to imagine that both Jetty and Tomcat already have their own
code for injecting the items from JNDI using the standard names
[1], so if simply had some way to tell either of them which jndi
names go with which fields we'd be good to go.
[1] Granted the spec doesn't require you to inject straight from
JNDI, but injection was intended to be done this way when the specs
were written (even SessionContext is now in JNDI) and I'd be really
surprised if there was anyone out there doing it differently.
I'd be interested in what Jetty and Tomcat have in this regard.
I took a quick look at Jetty and Tomcat source. Tomcat has some
complete looking code for injection via JNDI, except it seems it only
supports using annotations as the source of injection data, nothing
for xml as the source.
http://svn.apache.org/viewvc/tomcat/tc6.0.x/trunk/java/org/apache/
catalina/util/DefaultAnnotationProcessor.java?view=markup
Jetty doesn't seem to have anything in this area. I looked for any
references to javax.annotation and didn't find any. Greg, any
thoughts on what your plans are in this area?
