Java/Perl Question

if(SOCKNAME =~ m/^\d+$/) {
	$socket = IO::Socket::INET->new(Type => SOCK_STREAM, PeerAddr => SOCKHOST, PeerPort => SOCKNAME);
} else {
	$socket = IO::Socket::UNIX->new(Type => SOCK_STREAM, Peer => SOCKNAME);
}

This is a pieve of perl code that opens a socket on the localhost at a specified port.

The first part uses INET which I can program in java, the second part uses
some UNIX socket thingy that I'm not familiar with. There is a .sock file that this perl program calls and communicates with.

What I want to know is, how do I write a java program that opens a socket to a file in Linux ? /tmp/jd.sock is the file. I'm guessing this is the method that the perl program uses to communicate with the other perl program.

jd is a mp3player, and you can connect to it and queue up songs and cancel songs etc.


Ok not a very well organised post but you should get the jist and if you could help me that would be great !

Thanks,

Ro.

I've just looked and UNIX sockets are not support by standard java.

UNIX sockets are used for interprocess communication on unix like systems, search AF_UNIX o AF_LOCAL on google to find more information.

You should be able to configure the server part of the program to use normal IP sockets and that should work just fine with your java program.
