|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.
|
again, "work that contains the Program" is code that "contains" physically
the Program (maybe thinking import in programming terms can help).
If you were to write a piece that "contains" my classes (as in C&P or
"import") then that is work that contains "whole or part" of my work. That
is GPL'ed. Remember that **aggregation** is not covered by the license.
The distribution is not the work. The work we distribute that *does*
contain "part or whole" of jboss is the MBean stuff. Putting Tomcat in a
distribution with it is "aggregation", tomcat IS NOT WORK THAT CONTAINS
whole or part of jboss, it is also not work that is derived from jboss.
do people that distribute Apache on linux violate the GPL and should GPL
Apache??? no!!! apache the code, the work, ***doesn't contain*** linux, even
though the "webserver" works ON linux and "contains" linux...
it is because the work is "apache" even though the server is "apache+linux"
but **that is aggregation***
So...
marc
the license terms are laid out here:
http://www.gnu.org/copyleft/gpl.html
|Thanks,
| Aaron
