Hi,

I was searching for some method to provide file upload in admin console.

For that I checked src/web/plugin-admin.jsp and found out it is using org.apache.commons.fileupload. After a long search I found these two libraries:

src/web/WEB-INF/lib/commons-fileupload.jar
src/web/WEB-INF/lib/commons-io.jar

Both libraries include an LICENSE.txt which claims them as Apache License v2.0. Openfire itself is licensed under GnuGPLv2. According to wikipedia these two are not compatible! Migrating to GPLv3 would probably solve this problem.

The plugins clientControl, fastpath and userImportExport are using and older commons-fileupload-1.0.jar, which claims to be Apache License v1.1.

Question:

I want to use org.apache.commons.fileupload by myself. Does someone know if APL 1.1 is compatible with GPLv2?
