I am looking for advice about open source licensing. If it is not the
right mailing list, please accept my apologies. In that case, could you
direct me to the right place to ask my question?
We are developing a software that we want to release under an open
source license (ideally preventing reuse of our code in proprietary
software). The software uses some libraries with different open source
licenses. We are new to open source licensing and it is not clear for us
which open source licenses we can use. Could you provide advice on the
Our software uses 2 libraries. Those libraries are:
* Apache Derby, distributed under the terms of the Apache License,
* SWT, and some other Eclipse libraries, distributed under the terms
of the Eclipse Public License Version 1.0, except for some third party
We have not modified those libraries. We just use them, but as we want
to distribute a self contained version of our software we want to
distribute those libraries with our own code.
Our software is distributed under the form of a JAR file (similar to an
executable zip file). This JAR file contains our code and a directory
("libs") containing the libraries under the form of JAR files. Those JAR
files have been downloaded from their library webpage and included in
the "libs" repository without any modification.
From what we understood from the incompatibility between the GPLv3 and
the Eclipse Public License, we can not distribute our software under the
GPL v3 or under the "GPL v3 license, except for some third party content
(Apache Derby library and Eclipse libraries including SWT)".
Which open source licenses preventing reuse of our code in proprietary
software, which is not broken by the licenses of the 2 libraries and do
not break the licenses of the 2 libraries, can we use?
