With a "little" difference between the new version and the previous: Newer is GPL which means people who wrote a commercial application based on 2.x (LPGL) will open their sources if they want to use 3.x version.

I feel you are playing chess again.

Hi,

as initiator of the JPEd fork, I would like to congratulate Sasa for the
step to make JaWE fully available again. I started JPEd as an appendix
on the WfMOpen site (http://wfmopen.sf.net) because I was very annoyed
that the possibility to maintain our XPDL files -- including the layout
-- had gone away. I have always felt that the fork proofed one of the
concepts of Open Source, because it took only a rather small effort to
regain the control over a software that we needed and that we had
invested in, although the original authors had decided to go commercial
(though denied by Together AT, I still consider it rather obvious that
it was all about collecting license fees after having gained some
popularity).

While JPEd in its initial, JaWE-close version, satisfied our needs,
David Delbecq required additional features. So I transfered JPEd to an
SF project of its own. All credit for the further development and the
really nice home page goes to him.

When I built JPEd based on the JaWE sources, I changed the license from
LGPL to GPL (From LGPL 2.1: "You may opt to apply the terms of the
ordinary GNU General Public License instead of this License to a given
copy of the Library."). I have always felt that the GPL is more
appropriate for a tool (I'm not talking about libraries here!).

When Sasa decided to include features from JPEd in the new version of
JaWE, he therefore had no choice but to use the GPL, because the change
from LGPL to GPL cannot be reversed.

Of course, I don't know about Sasa's motivation. Maybe he is "playing
chess again" (as Pablo Beltran assumes) and I haven't found out yet what
he's aiming at. But for now I simply assume that JaWE licenses haven't
proofed as successful as anticipated. So integrating the JPEd features
and thus making JaWE a stronger tool puts him in a better position to
sell support for JaWE. But this is pure speculation from my side.

Personally, I feel very happy about having a JaWE (or TWE) with bundled
additional features from two development branches fully available again.
(Of course, learning from experience, I have downloaded the sources
immediately.) My sympathy with "People who wrote a commercial
application based on 2.x (LPGL)" (cited from Pablo Beltran's mail) is
very limited. If the add-on is really substantial and worth it, the
author should improve the GPL'ed version to support plugin functions as
required by the commercial feature and provide the commercial feature as
plugin. Nothing from the GPL prevents that. And if it is only a minor
feature not worth this effort, why should the author profit from the
work freely provided by others? (By the way, does anybody know the
commercial version referred to? Neither googling for "TWE based" nor for
"JaWE based" resulted in significant hits...)

Regards and congratulations again Sasa,

    Michael

Hi,

"Playing chess" means every major release (1.x,2.x,3.x)  of Jawe and Shark
introduces changes to impede and difficult commercial 3rd party tools build on
them.

You see,

JaWe 1.x -> GPL
Shark 1.x -> GPL
----------------------------------
Jawe 2.x-> LGPL (Good!)
Shark 2.x -> LGPL (Good!)

At this point, a commercial branch is started by Together-> Hard difficulties
begun to integrate JAWE into Shark to build a Professional alternative. You can
read them on the forum.
But writing enough good challenger alternatives to Together's Professional
version is still possible with a lot of effort.You can see some of them
searching on the Internet. -> How to avoid them?

----------------------------------
JaWe 3.x -> GPL -> Avoids using it commercially -> No more commercial
challengers. Yes, you gain a cookie! You think you are winning because some
additional stuff functionality has been included, but you are loosing because
nobody will seriously try to improve Shark (nor JaWE).
Shark 3.x -> ??? No matters, because without JaWE... it's no-dangerous.  I
guess it'll remain LGPL.

I think they are playing chess because they give you a Tower but you lost the
Queen.

IMHO, GPL is the bad license for Open Source's success.

Best regards,
Pablo.

"Tower" is "Rook". Sorry for bad translation from Spanish :)

I'm still curious about commercial JaWe 2.x based products and what kind
of value they add to JaWe. As mentioned before, I failed to find any.
Couldn't you be more specific and give us some links?

Hi,

YAPROC (developed by me) is a good example. It brings all the power of Shark and JaWE into the Eclipse platform.

Here is the link:

http://www.upversion.com/index.php?option=com_content&view=article&id=55&Itemid=58

It adds some additional nice features:
* audit/visualize/reproduce step by step and graphically the history of a process,
* reports based on SQL which could be called from your favourite reporting tool (CrystaReports, JasperResports,...)
* ...

YAPROC isn't too much popular but each month around 5-10 different people download the sources. Most of the from the USA.

Those folks could write a new version giving workflow support based on Shark/JaWE to the rest of Eclipse plugins. I think it would be really nice. But now, I think they could be discouraged due the new Jawe 3.0 GPL license.

Bests regards,
Pablo

PS: In the lastest JaWE's change log you can see more "chess" movements: the API for Shark has been dropped from the Open Source version. I think people don't understand what really it means. I'll explain it to them: a big stone on the way between Shark and JaWe integration.

It's a bad example because it's neither commercial nor closed source. So
I'm still curious about commercial JaWe 2.x based products...

:)

It's the BEST example because it was not open source at the begginig and it was developed to be a commercial product. But just some weeks after the first release I discontinued it and I published the source... And I didn''t waste more time, effort and money to work on it. Now, after the JaWE 3.0 release, I take the right decission in the right moment.

And now I develop commercial projects on truly open source projects. Not Shark nor JaWE :).

Best regards,
Pablo.
