Something like this maybe?
String[] cmd = {
"/bin/sh",
"-c",
"ps -eo rss,comm --sort rss"
};
Process p = Runtime.getRuntime().exec(cmd);
p.waitFor();
BufferedReader buf = new BufferedReader(new InputStreamReader(
p.getInputStream()));
String line = "";
String output = "";
while ((line = buf.readLine()) != null)
{
if(line.indexOf("java") > 0)
{
output += line + "\n";
}
}
out.println(output);
System.out.println(output);
