licenses for ObjectWeb components & Apache/OW collaboration
Dear Brian and Greg,
We (ObjectWeb) owe you a response on possible changes of licenses for
ObjectWeb components, to further the possibility for collaboration between
Apache and ObjectWeb.
I am happy to report that both the ObjectWeb Board and the ObjectWeb
College of Architects have agreed that, for ObjectWeb components that are
to be developed collaboratively with the Apache Software Foundation, a
change of license from LGPL to BSD is encouraged.
Ultimately, of course, the final responsibility for effecting such a change
lies with the copyright holders of the source code under consideration.
For the two cases at hand, namely the JOTM transaction engine and the ASM
bytecode manipulator, I am happy to report that the respective copyright
holders are ready to make this change, should the ASF require it.
As we discussed in previous messages, I believe such a policy meets the
requirements of the ASF for incorporating ObjectWeb components in its code
base.
Best regards,
Jean-Bernard

I can't speak for ObjectWeb on licensing all of JOnAS under the BSD. I
can say that even if they were to do so, there might still be good reason
to have an more than one BSD-licensed Sun-certified J2EE server.
"Duplication of effort" should be avoided of course, but even when writing
standards-conformant software, there can be genuinely different approaches
with different tradeoffs - speed vs. code complexity, for example, or
small runtime memory size versus everything else. Furthermore, if two
teams are separately trying to solve the same problem, your odds of
finding the right answer are greater than if you just had one team of
similar size, and both teams can probably enjoy the fruits of the winning
team's efforts.
One thing I've suggested to a couple of others is the idea of an "open
source J2EE implementors' forum", a mailing list hosted some place
"neutral" (Jean-Pierre suggested java.net, that makes sense to me) which
would be a place where developers from Geronimo, JOnAS, heck even JBoss
could discuss topics germane to any open source J2EE, from certification
to further code sharing to... who knows.

I don't believe having multiple open-source J2EE projects is a loss of
energy. Nor is it a war.
It is closer to sound competition, or "coopetition"; See how we at
ObjectWeb already use apache components, like Tomcat; also, on the
"political" ground, multiple actors have proven to be stronger, for
example to make Sun's position evolve concerning certification.
Such a process makes each of us better, it's just like we are multiple
participants to a marathon race, a condition to run fast.
I am also convinced we - the IT industry - need even more than 2
implementations to make open-source J2EE credible (at least 2 certified
ones would be good). Then we'll be the big alternative to commercial app
servers.
So, welcome Geronimo !

Pierre-Yves Gibello - ExperLog (and ObjectWeb board)

Brian and Jean-Bernard,
maybe this is a silly question, but somewhere
(http://incubator.apache.org/projects/geronimo-proposal.html) I have
read that one of the main purposes behind starting Geronimo project was
absence of ASF (or BSD like) licensed J2EE server. If Objectweb is
willing to change license on some of its components, maybe it would be
possible to change the license of Jonas as well.
Question: Would that be possible / feasible at all ?
In so then there would be no need to reimplement the whole J2EE stack
again just to use a different license.
Not sure what are other reasons behind Geronimo, but if one of them is
to use already available J2EE stack components other than then ones
provided by Objectweb, wouldn't it be better to just improve Jonas to be
truly plug an play with ability to use for example different EJB
container (OpenEJB)?
I believe implementation of full J2EE spec is not a trivial task as you
can see from the history of Jonas, JBoss and others. Change of license
could save (or redirect to more or faster achievable goals) lots of
development resources if license is the only reason and also help
establish de-facto standard (similar to Apache HTTP server, or Tomcat
JSP container) faster (especially since hopefully Jonas will be soon
J2EE certified thanks to the Sun's scholarship Objectweb received).
Hope this is not too off topic,
Miro Halas

That's terrific news, Jean-Bernard. Thanks!
Geronimo developers: this should encourage you to look at the code
ObjectWeb has implemented for its J2EE server, to see if there are any
places where collaboration would be preferable to reimplementation. To be
clear, BSD-licensed code from any party may be incorporated into Apache
releases licensed under the Apache license. I would encourage such
collaboration work to take place wherever the "home" is for such code,
rather than importing the code into Apache's CVS trees and creating (even
unintentionally) an Apache-specific branch. Perhaps someone could lead a
discussion about the dev & release cycle that accounts for such
externally-developed components. Be aware that the agreements that cover
your contributions to the ASF would not apply to contributions you'd make
to ObjectWeb components; I don't know if ObjectWeb has contributor
agreements like we do.
I now leave this issue in the capable hands of the Geronimo community.

Agreed - great news!
I've been using ASM a lot lately (on Groovy http://groovy.codehaus.org)
and it rocks for generating bytecode dynamically. We can definitely use
ASM for any bytecode generation stuff we need.

Great news! I use JOTM for JettyPlus's transaction manager, so I'm very
pleased to see it will be available for Geronimo too.
At least initially, we should be able to work with JOTM as a 3rd party
jar served from ibiblio, and create a Geronimo environment where the
actual transaction manager is a pluggable component.
cheers,
Jan

This is great! It will allow us to work with JOTM rather than build our
own TM from the ground up thereby duplicating efforts (even though there
has already been some work put into building a small Geronimo TM). Does
this relicensing of JOTM cover the Advanced Developments as well?
