Can't execute Runtime.getRuntime().exec()

Hi,

--- test1.jsp --
<%
        Runtime.getRuntime().exec("/usr/bin/ls > /tmp/test" );
%>

test1.jsp did not execute.

What't the problem?

Thanks advance

Problem is ">" is a shell command and Java doesn't exec within a shell. 
You need to run a shell, and pass the arguments to the shell.  It's
outlined in Chapter 13 of my book.  http://www.servlets.com/book. 
Examples are online.
