Hi Howard,
Thanks for the kind words about Nuxeo as an application, and I hope
we will also satisfy you as a platform (this is our main focus, anyway).
Regarding hot deployment: I agree this is a desirable feature for
developers, and using OSGi should help us in this direction, but I've
been told by Bogdan, the lead architect for Nuxeo Runtime, that this
is a difficult problem (and when Bogdan says something is difficult,
it *is* really difficult).
Nuxeo 5.1.0.GA has been tagged today (we're still working on some
minor packaging issues before issuing the announcement), and hence,
I'm sorry to tell you that it won't ship with hot deployment.
OTOH, I can't make any promises before Bogdan has looked deeper into
this problem, but we will try to work out a solution for Nuxeo 5.2.
Of course, if anyone on this list is willing to help, this would be
great.

Bonjour, Nuxeo folks --
Although I've been tracking & admiring your work through your
releases,
snapshots, code, jira, trac, sites, docs, and the archives of this
list, I've
never posted here before. So I'll restrict this "hello nuxeo world"
message to a
highlevel theme.
I really like and agree with (at least 90% of) your architectural
choices, and
think you guys are doing a fine job (modulo how ambitious you have
been for this
cycle) following through with implementation as well. I am already
recommending
Nuxeo as an ECM *application*, and have high hopes for it as a high-
level
*platform*.
But then, people don't post here *just* to say nice things, do
they? :) So here
is my top concern:
What are the plans for hot-deployment of Plugins (those which
include EJB3s; not
just web components) placed into the server/default/deploy/
nuxeo.ear/plugins
directory after server startup?
Several places in the docs have statements that hot-deployment will
be available
on platforms that support it; and JBoss certainly is a platform
that does. I
have developed several plugins based on the Maven archetype you've
provided
(including some with EJB3 Entities, based on my previous SEAM work,
and
everything works great :)).... but... I have never seen any
indication of even
partial deployment except with a full server shutdown and startup.
I was
initially quite excited about OSGi coming to JBoss, and I have found
many hints that you are working toward hot-deployment of your
almost-OSGi
plugins... but nothing visible in JIRA, and I have no solid sense
of where it
fits in your priorities, or in relation to 5.1 GA.
As a long-time JBoss developer, I can say that hot-deployment/hot-
redeployment
and the resulting rapid cycle times are key to the enjoyment and
productivity I
have had with JBoss over the past 7 years, and with SEAM over the
past 2. Having
already invested hundreds of hours into Nuxeo over the past 5
months, and with
heavy coding commitments during the upcoming months, I sincerely
hope the 5.1 GA
will ship with hot-deployment.
