Subject Re: Log4cxx licensing
Date Tue, 27 Mar 2012 08:57:02 GMT
Hi again Johnny,

As i'm currently working on Fedora, i've looked at log4cxx RPMs for
this distribution, and there is the Berkeley dependance too... And
reading the SleepyCat license, it seems that you were right about the
use of this library in proprietary software.

Anyway, it depends in my understanding of english (ouch) and
understanding of text license (ouch 2)... By reading the license it
seems that the source of any software using it should be available,
but maybe is it considered that log4cxx uses the DB lib, and your
software only use log4cxx ? Quite complicated, but it's true it's
quite strange to see such a dependance in a software under the Apache
License 2...
