Interpreting java output stream as system commands in Solaris
Hi there again,
Running Solaris 10 with built-in Java. Seems to compile and run fine.
Problem is: Say I want to see contents of current directory. In a shell, I'd just write "ls" and it outputs the content.
When I write a Java file, I have the following line:
System.out.println("ls");
But when I run the file, what it does is echo "ls" itself to the screen, instead of sending it to the shell as a command (so instead of seeing directory contents all I see is the text "ls"). What should I change the above line to, so that "ls" is sent to the shell as a command, instead of just echoed?

DESCRIPTION
The JPackage Project has two primary goals:
- To provide a coherent set of Java software packages for Linux, satisfying all quality requirements of other applications.
- To establish an efficient and robust policy for Java software packaging and installation.
We focus on free and open source software whenever possible. For convenience, we also provide non-free packages without the restricted
source code.
Our RPMs are generic in that they should work on any RPM based Linux distribution (Mandriva, Red Hat, SuSE, others). Other packaging format
suggestions are welcome too.
