Subject Re: [jira] [Created] (LEGAL-138) Can the extjs javascript library be used? If so, in what capacity?
Date Tue, 19 Jun 2012 06:11:30 GMT

The Apache Software Foundation does not allow its own projects to
distribute software under licenses more restrictive than the Apache
License. Apache 2 software can therefore be included in GPLv3 projects,
because the GPLv3 license accepts our software into GPLv3 works. However,
GPLv3 software cannot be included in Apache projects. The licenses are
incompatible in one direction only.

I would advice to find any other alternate for extjs.
