I am trying from a java class executed in win2000 to launch an application on another Linux machine in the same local network. The same "Runtime.getRuntime().exec("....")" command I use to attempt this action works if the class is executed locally on the Linux machine but not at distance. This is how I try it and I receive an error: (error=67): Runtime rt = Runtime.getRuntime(); String[] callAndArgs = {"//server/process","args for process"}; try { Process child = rt.exec(callAndArgs); child.waitFor(); } catch(Exception e) { }    More>>

works if the class is executed locally on the Linux machine but not at distance.

This is how I try it and I receive an error: (error=67):

Runtime rt = Runtime.getRuntime();
String[] callAndArgs = {"//server/process","args for process"};
try
{
Process child = rt.exec(callAndArgs);
child.waitFor();
}
catch(Exception e)
{
}

The Runtime.exec() call executes
a command locally, just as if you had typed
it into a shell. It has no capability to launch
processes on remote machines.

There are many ways to build applications
that use distributed processing - Web servers,
application servers, remote-shell protocols
like rsh and ssh - but those all involve
setting up something on the server and
executing the appropriate protocols on
the client. Using Runtime.exec()
in the way described here will not get you there.
