I see these threads UNIX socket implementation for Java? and http://forums.sun.com/thread.jspa?threadID=713266.
The second link says that Java already supports UNIX Domain Socket. If that's true what class do I need to implement from Java?.
From the first link, it says that Java does not support UNIX Domain Socket. If you need UNIX Domain Socket you must use a 3rd-party library.
So, which is it?
Java cannot create or access Unix Domain Sockets without using a 3rd party (native) library. The last comment on the second link above mentions this.
The first link has some good (and correct) information on it.
