Question

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?

Was it helpful?

Solution

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.

OTHER TIPS

You could use junixsocket: https://github.com/kohlschutter/junixsocket

It provides AF-UNIX support via a JNI library, utilizing the Java Socket API. It even allows connecting to MySQL from Java (Connector/J) via Unix sockets.

Netty also supports it since version 4.0.26: https://github.com/netty/netty/pull/3344
