License Apache and LGPL
Hello,
I created RTFTemplate project, RTF template engine (if you are interested,
see http://rtftemplate.sourceforge.net/index.html) and I use LGPL license.
But RTFTemplate use Jakarta Velocity library which is Apache license. Can I
use LGPL license? Must I change license LGPL to Apache license? Can I use
GPL license otherwise?
Thank's for your response.
Angelo

Hi Angelo,
>From the point of view of Apache and the Apache licence, you can take the
Apache-licensed Velocity and include either its source or its binary in
your work.
Provided you obey the clauses of the ASL 2.0:
http://www.apache.org/licenses/LICENSE-2.0
Chiefly:
* Include a copy of the ASL licence with the ASL licenced-work (ie
Velocity in this case).
* Include a copy of the NOTICE file with the licence.
* If you modify the Velocity source, you keep the copyright/licence notice
that's in the source code; and note that you changed said source.
There's more in there, but my non-lawyer brain thinks those are the
main ones.

By the way, the jboss project already does this: combines its own GPL
software with Apache projects like Tomcat.

The best place to ask this question is probably on the list
legal-discuss@apache.org
(you might want to check the archives first in case the answer is
already there).
However I believe that it is ok to combine Apache software with GPL or
LGPL software (as long as the acknowledgement clause is followed). The
resulting combination can legally be distributed under the GPL (or LGPL)
licence.
Of course the result *cannot* be distributed just under the Apache
license, which is why Apache projects cannot include GPL/LGPL code
directly.
Note: I am not a lawyer. The legal-discuss list is the best place for a
professional opinion. There was some discussion a while ago about
creating a web-page with these sorts of questions answered, but I don't
think it exists yet...

Simon
