Exception during parsing params from a form? I get parameters from a html form. I parse the integer one in the JSP file, but I get exception. Is there anyway I can get the integer, or I have to make it a String?

    String name = request.getParameter("name");
    String year_prime = request.getParameter("year");
    int year, id;

    try{
    year = Integer.parseInt(year_prime);
    }catch(Exception e1){
    year = 0; 
    }

I keep getting with the year=0...
