Hi Pasquale,

Hello,
I'd need to create some java apis who would allow to interact with openvswitch, creating bridges, adding ports, creating gre tunnels...in short: the exact same thing ovs-vsctl does.

As c code seems fairly complex I write here to ask your help.
I have two ideas:
1)Make some java bindings using jna. This would require a .so version of ovs-vsctl..if making it is not complicated it would be the fastest option, but I would need some help in order to create it (or, if some good guy wants to compile it for me I would really appreciate it). 2)From what I understood ovs-vsctl just interacts with the db using json, so I could create my own library. But I don't know on which port db waits, if some authentication is needed, how tables are made, what syntax use, ecc. So in this case I would need some reference.

Depending on what you want do exactly, you may find the OpenDaylight OVSDB Client project useful: it implements an OVSDB client library in Java, and exports a REST northbound API. It also has code to do some of the common ovs-vsctl functions like adding and deleting ports, etc.

Not to mention that if I get this library done I would share it with you and the community under the same license openvswitch is released (should be lgpl right?).
