Bill,
In that case, I think the existing documentation for CanDI configuration
suffices:
http://caucho.com/resin-4.0/admin/config-candi.xtp.
Basically the key concepts we would like to see (strictly in order of
priority) are:
* Compact, "Java-like" schema-based syntax, similar to the Seam Config
module/CanDI XML.
* Being able to configure CDI and EJB using this syntax.
* Being able to load property file values/environment property values
through EL (this might be a good enhancement to EL regardless of this).
We allude to this in the docs, but it is not completely hashed out.
* Being able to configure all Java EE managed beans including Servlets
using this syntax. Like Resin configuration we would actually prefer
that most Java EE configuration looks like managed bean configuration
using XML.
* Have separate schemas for current XML DD values that do not match the
managed beans/annotation paradigm well. Taking the web.xml as an
example, things like module names, session configuration, etc can go in
such schemas. I think the number of tags that genuinely fall in this
category is quite small.
* Being able to configure multiple things in any Java EE XML DD using
schemas. For example, you would be able to configure CDI beans in
web.xml if you want.
* Let all Java EE XML DDs have capabilities similar to web.xml fragments.
Let me know if any of this requires further details. Since we started
down this path, I'd prefer to follow this to the end. I do think there
is tangible befits for developers in such an enhancement and at least
some of it is doable in Java EE 7 if there is a desire to do it. We in
the Resin team can see if we have the resources to contribute to this
significantly if resources are an issue (I do feel a little funny
soliciting Oracle with an offer of additional resources from a tiny
company like Caucho :-)).
Cheers,
Reza
