Here is what Sam Ruby has to say on that subject: http://intertwingly.net/blog/2007/06/29/GPL-Compatible Pay particular attention to the paragraph that begins "I’ll attempt to do that and more:" --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT and ExtGWT Licensing
This is the section from Apache about compatibility: This licensing incompatibility applies *only* when some Apache project software becomes a derivative work of some GPLv3 software, because then the Apache software would have to be distributed under GPLv3. This would be incompatible with ASF's requirement that all Apache software must be distributed under the Apache License 2.0. As far as the license is converned, when ExtGWT extends a GWT class it is a derivitive work in the eyes of the GPL, so the above clause is true.

GWT and ExtGWT Licensing
I just wanted to ask you guys about this topic as our IP lawyers have found a potential problem. * ExtGWT extends classes in GWT therefore creating a derivative work. * ExtGWT is licensed under the GPLv3 and GWT under ASFv2. Now, we know that these are compatible. But, only ONE WAY! You can include GPLv3 code in your ASFv2 licensed project, but NOT the other way around. So, if I wanted to distribute my ExtGWT app under the GPLv3 (open sourcing all my code which does not require an Ext license) I cannot, as I cannot relicense the ASF licensed code (GWT). As far as we can see there is NO way of legally distributing an ExtGWT applicattion under the GPLv3. IANAL, so I can only go on what our lawyers tell me. This is indeed a blow to us, as I cannot see a way round this. If any of you have distributed an ExtGWT app under the GPLv3, then you have broken the terms of the ASFv2 and therefore have no rights to distribute GWT! I'm off to bed now :( --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
