With Branch_5_x starting off the newer jboss-bootstrap, I've been
prototyping a bit with an Embedded launcher for AS. Goals are:
* User defines one dependency upon org.jboss.embedded:someArtifact
* Entire AS dependency set (==all JARs used in the runtime) are
brought in and are available for use in tests and upon the runtime
test classpath
The key here is that the AS dependency set wholly ends up on the
application ClassLoader. Later on child>parent delegation takes place
and the app CL is the defining CL for everything (except webapps or
other things which define explicit scoping).
What I need is a mechanism to bring in the AS dependency tree in one
fell swoop. Most of this is accomplished by:
org.jboss.jbossas:jboss-as-build (All AS modules and *most* 3rdparty
deps)
But that doesn't account for everything. I also need to explicitly
define, at a minimum:
org.jboss.jbossas:jboss-as-management:jsr77
jboss.web:jsp-api
jboss.web:el-api
This is because jboss.web:jbossweb doesn't define any
dependencies.
...probably more stuff I haven't yet discovered.
I know
JBossTS doesn't have a proper pom as well. See
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/projects/ejb3/trunk/jt...
.
I'd be much cleaner if AS itself could provide one POM artifact which
held all deps. Then Embedded could bring in this one dependency and
get everything else transitively. Embedded versions then become tied
to AS releases.
Can we add this? Is there a better way that occurs to anyone?
I think it's
more related to having proper poms for sub-projects.
Let's go on a case-by-case. If necessary we can always define virtual
projects which do have a proper pom, tying the artifacts together.

BTW I've got a series of docs in progress for the Wiki soon, but have
preferred to do proof-of-concept before posting it. I'll ping back
here when there's docs and source to comb through.
* Alternative Boot Method *
There is another way to boot AS, which is to be selective about the
classes allowed upon the application ClassLoader. This is the current
solution taken by AS Main, and the specialized assembly which
cherry-picks eligible classes is provided by run.jar.
This gives us another Embedded mode which uses a similar assembly on
the application ClassLoader, and then the rest of the classes are
brought in via the standard jboss-cl models as we normally do.
The drawback to this approach is that the user is not able to
reference classes such as the MC Kernel because this imposes invalid
parent>child ClassLoader delegation resulting in NCDFE. So it's, at
the moment, good for little more than starting and shutting down AS.
