Because several projects in Sun are evaluating Drools, it is being

Out of interest is Drools used in
any sun apps, or are you just
distributing it incase third parties need it?
I'm weighing the pros and cons of building from source locally or
using the distributed binaries. So, with that in mind I would like
some help understanding an issue related to your binary distribution:
While it is very convenient that Drools' binary distribution contains
its dependencies, I'm curious how you are complying with the licenses
of those dependencies, particularly those that are third-party. I see
no licensing information or attribution in the tarball/zip that I
downloaded (except for the ASL license).
Take xpp3 for example; xpp3-min-1.1.3.4.O.jar is included in the zip I
downloaded. Independently, I found this in the xpp3 source tarball
(see the attachment for the complete license):
2. Redistributions in binary form must reproduce the above copyright
notice, this list of conditions and the following disclaimer in
the documentation and/or other materials provided with the
distribution.
...
Alternately, this acknowledgment may appear in the software itself,
if and wherever such third-party acknowledgments normally appear.
Does this information appear in the binary package? I've read the
wiki page on dependencies and done some greps in the source download
and binary download and haven't found it...
We use Maven and maven specifies
the dependency poms, which specifies
and provides the licenses. We actually use Maven to suck in the
dependencies into the bin zip. Maybe we should think about including a
licenses for each dependency too, for that to happen I'd like to see it
automated as part of the maven build. I don't have time for that now, if
anyone wants to submit a patch to automate maven for this, let me know.
