从java servlet运行命令行php脚本

Is there any way to run a php command line script (server side) from a javaservlet?? I've been trying and I don't get any exception but the script doesn't do what it supposed it does. I don't know if I'm breaking any security rules (like applets have). I'm using this code:

Runtime runtime = Runtime.getRuntime();
Process process = null;
try
{
    process = runtime.exec("php " + "wsaa-client.php wsfe" + " wsfe");
}
catch(Exception e)
{
    out.println("<h4>Runned!</h4>");
}

And everything look ok. Even I have a process running called: php-cgi.exe

Any help/suggestion?

You could try to use absolute path of both the PHP and the wsaa-client.php file. Please also catch exception and print out the exception.
