Denes,
Yes, the arrow means uses. As for the term "deployment manager", I got
that from Weston's earlier e-mail
Excerpt from Weston Price:
"I have thought of it in terms of a deployment manager (as Chris alluded to
earlier this morning). The manager would be responsible for coordinating the
interaction between the verification engine and the deployment engine....sort
of a controller,that way the two can be loosely coupled relying on an
external agent to provide an higher level of service"
Basically the DeploymentManager would first Send the archive into the Verification Engine to make sure it was assembled correctly. If that passed then the Deployment Manager would send the archive into the deployment engine to actually be deployed into Gerinomo.
A point to note is that the Verification engine can also be used in other places, like Weston said. We could make it an Ant task, or attach it to this gerinomo gui so developers could verify their archive before sending it to Gerinomo for deployment.

Not sure about what DeploymentManager really is. Is it the deploy tool,
some daemon on server, or both?

Since I'm weird and think better in pictures, I tried to draw what you
were describing. Do I have the correct Idea of your vision?
The image is attached. Hope this helps others out also.

In this scenario, the verifier will have to interface
with the deployer. I would definitely like to
implement the SPI for the deployer.
Q: Should the deployer be responsible for ensuring
bean consistency, e.g., entity bean cmr mapping vs
databases and relational mappings, or any such other
technical issues (realms checking, etc.)?
Chris, if this is what we'd work on, I'd like to come
up with a list potential technical problems we could
encounter to ensure just integrity of the DD file.

That is exactly what i was thinking. This is the
object model that has been defined in the deployment
spec... under Tool Provider Interfaces. There are
also
some other classes, exceptions and interfaces that
both modules might use.

Ditto on all of that! Quite honestly...the

deployer.
Something along that lines at a high level. we
can
reuse both engines for CLI and the GUI.

+1 You've convinced me. That would be a bad

tool to have as a
developer.
Plus, the deployment team could use it if they
want
to verify the
archive schema before they start deploying it.
Count me in!

I agree completely. I think what we are
talking
about are two modules
that are
close cousins. The verification manager is
again,
the "front-line" of
defense
for the deployment manager. I would assume the
deployment manager would
deal
with critical errors such as
LinkageConstraints,
incorrect classfile
versions
etc. while the verfication manager will handle
actual semantic
fallibities in
the deployment descriptors based upon the
existing
specifications.
The reason I mentioned a seperate
verification
module was that I
would
developers (hell, I know I would) like an
engine
that given a deployment
platform could validate their archive before
ever
trying to drop it in
the
chute. This would save a lot of time largely
due
to
the fact that XML
descriptors are not typed and you don't know
if
they
are "correct" at
compile
time. I suppose the biggest win in all of this
in my
opion would be to
provide hooks for an ANT task that would
verify
the
archive during
compile
time.
Regards,
Weston

I mean we don't
want
to deploy something that the J2EE server
will
not
accept.
Maybe these 2 groups should work close
together.

Our module is just going to check and

whether or not a given unit of
deployment
is deployable on a j2ee server or not.
Nothing more..nothing less.
Building this unit will be our
mission..right
weston??

And even further, let's clarify the
verification
is
a completely different
animal than actual deployment. Am I
correct
on
this
one at least in terms of
the way we are thinking about this module?
