    Okay Im using request.getParameter to retrieve a value from an actual address entered in at the top of the screen.

    I was just wondering if Ive got this big long string with
    tryryrury&cmd=0

    would
    req.getParameter("cmd")

    return a string saying "0"?

    Thats sounds about right.......

    Do you have a choice of whether or not you have to use JSP?

    You can do stuff like this as well 
    Map<String,String[]> parameters = req.getParameterMap();
for(String key: req.keySet()) 
{      
       System.out.println("KEY: "+key+" - VALUE: "+parameters.get(key)[0]);
}

    Which would list all parameters and their values, handy for checking multiple parameters.
