Fwd: [jboss-dev] Include Web Beans RI in next JBoss 5 release
by Pete Muir
As Ales says, Web Beans is being developed as a standalone project,
it's not using the Seam codebase at all. We should probably rename the
Seam deployer to seam2.deployer.
Also, unlike Seam, Web Beans will be distributed as part of the app
server, rather than as an application library.

Fine by me :-) The big update we currently have to do in 5.0.0.GA (and
the problem Scott saw) is around updating EJB3; this update is in 5.0.1.

I cetainly don't want to hold up AS. This was why I suggested it as a
preview of some sort - so that the JBoss AS release isn't held up by
not having a stable WB release. Worst comes to worst, we decide WB
isn't ready to integrate into AS 5.1.0.GA, and we just remove the
deployer (which is why the point about the WB libraries being isolated
is important).
But I think saying "all projects which make up AS *must* be in GA" is
too conservative - there are cases (like this one) where we want to
get some tech preview into the AS to give people a taste, and get
feedback. So, I would amend it to be "all projects must which make us
AS *must* be in GA or marked as tech preview. If the project is marked
tech preview, it should be isolated from the AS, and easy to remove".
> The point of my email really has nothing to do with Web Beans
The status is that we have preview releases we would like to get
feedback on. We probably won't have a GA by the time AS 5.1 goes out,
but that doesn't stop the features we do have (and the integration)
being relatively stable.

Sounds sensible to me. So, tell me the window, and I'll get the work
in for that window :-)

JBoss Query
by div_gect
Hi
Here i m working on custom filter java file for JBoss Logging. I m
giving the entry of the java file in log4j.xml. My problem is that - if
the java file is in default package and its class file is in
jboss\server\default\conf then that class is instantiating fine but if
that java file is in package
com.propo.tools.mergemanager.profiles(where i want) and its package
entry is in java file then this file is not getting instantiated
properly by server. Can anyone help me here.
Thanks And Regards
Divya Garg

Re: [jboss-dev] Include Web Beans RI in next JBoss 5 release
by Pete Muir
It's very likely the EJB3 update failed (again, most likely because
you don't have ANT_HOME set) [1]. Unfortunately the updater script in
the alpha1 release didn't fail if the EJB3 update fails (now fixed for
the upcoming alpha2).

JBoss Software Patterns
by chamandi podi
Hello All,
We are a group of students (six to be exact) currently
working on an assignment of a course on Software Patterns which is
part of our Master's Programme. The assignment involves the mining and
evaluation of both architectural and design patterns from a
non-trivial open source project. We have chosen JBoss for this
assignment and have prepared a report which includes our research to
understand the architecture of JBoss, description of relevant patterns
and a brief evaluation at the end. The report itself is a result of
four weeks of work, keeping in mind that all the students in the group
also have two other courses to follow. Even though, the report is a
work in progress, it contains all the important elements required for
the assignment.
We would be highly obliged if any (many) of you could
take a quick look at the report and give us some feedback (positive as
well as negative). Comments or suggestions regarding the amount of
research done , our understanding of the architecture and pattern
extraction / evaluation would be really helpful for us. If you cannot
do so, we would really appreciate it if you could point us to some
person (or group) who could help us.
Best Regards,
Cheri
