|Marc,
| I'm on your side. I would *really* like to be able to use jBoss.
|However:
|
| Please interpret the following passage of the GPL, and tell us how
|it applies to an app server based on software like Apache, Tomcat, Avalon,
|Castor, Tyrex, PostgreSQL, and jBoss. Specifically, imagine I want to
|make available a single download for a full open-source J2EE app server.
|Do you think it is possible to include jBoss with non-GPL packages?
|
|2.b.) You must cause any work that you distribute or publish, that in
|whole or in part contains or is derived from the Program or any part
|thereof, to be licensed as a whole at no charge to all third parties under
|the terms of this License.
Ok...
So a work that contains "part or whole" of another work, is one that
contains (maybe thinking import will help, or even cut and paste) the work
to create the new work. If you write a piece that "contains" my work (as in
import or cut and paste) then you must GPL, since the work contains part of
my work, btw that is the strongest case of containment (physical presence of
my work in your work), and of course GPL applies, "modified" or "derived"
are other level (less strong, you can "derive" from my work and not
physically "contain" it).
Now a work called "server" is **aggregation** and the pieces are not
"containment" nor "derived" nor "modified" of each other, they are
aggregated. What is "derived" and "contained" in our case are the MBeans
adapters (they include a Logger) and these are GPL. But Tomcat doesn't
contain or modify or derive from jboss.
Does a "webserver" contain linux or not? is the work "apache" derived from
Linux, (some could say yes through system calls but "applications normal use
of sys lib" are not covered by Linus) does the work "apache" contain "part
or whole" of the work Linux. ? .. right :)))
No! That is called "aggregation" and is explicitly not covered by the
license (read that passage).
YES it is possible to aggregate Apache+Tomcat (but isn't tomcat going to do
http as well as?;-), Avalon (F we need JMX man, come on the 77 board ;-)
Castor, Tyrex (cause assaf still kicks ass), PostgreSQL and jBOSS.
And yes!! it is possible to include GPL packages with non-GPL packages that
are not work containing the GPL work (any Linux distro will do ...)
