Run Batch File Or Command From JSP

I have a simple JSP file, code is below. I'm trying to run a batch file that simply contains the line :

java -ss262144 -oss819200 -classpath Topics.jar Building

but having no luck. Any ideas?

<%@ page language="java" import="java.io.*" %>

<%

try {

Runtime rt = Runtime.getRuntime();

Process p = rt.exec("c:/test.bat");

out.print("<center><a href='javascript:history.go(-1)'>Return</a>");

}

catch(Exception e){e.printStackTrace();

out.print("no");

}

%>
