Which Java middleware uses the agplv3 open source protocol
Description of AGPL agreement
AGPL is a supplement to GPL, adding some restrictions on the basis of GPL. The prerequisite for GPL constraints to take effect is that the software is "published". Some companies use GPL components to write web systems, but do not publish the system, and only use this system to provide services online, thus avoiding open source system code. The AGPL requires that if the code used in the cloud service (ie saas) is the license, the code of the cloud service must also be open source.
