Asunto: Re: how to pipe values from select-Tag ?


Hi there,

WOW this is the way I had it long time ago...
Well thank you veryy much, this error message has disappeared but...
please look at this :

!!!!!!!!!!! // Values are filled with projectNames...checked in HTML-code

out.println("<select name=\"proField\" "
+"<option><---------------------------------------------------></option>");
for(i = 1; i<length;i=i+2)
{
    out.println("<option value=\""+vec.get(i)+"\">"+vec.get(i)+"</option>");
}
   out.println("</select>");
      i=0;

out.println("<FORM ACTION =
\"http://10.48.229.45/examples/servlet/SelectedProject\" METHOD = \"GET\">"+
"<input type = \"submit\" name=\"edit\" value = \" edit\" height=\"20\"
width=\"10\">"+
"<input type=\"hidden\" name=\"alias\" value=\""+alias+"\" >");
out.println("</form>"+

////////////////////////////////////////////////////////////////////////////
////////////////////////////////////


public class SelectedProject extends HttpServlet implements
SingleThreadModel{

        private static String alias = "";

        private static String path="";
        String gbpfad = "gb.txt";
        public void doGet (HttpServletRequest requ,HttpServletResponse resp)
                     throws ServletException, IOException
    {

            String[] pfad = requ.getParameterValues("proField");

           // NullPointerException because pfad=null ????
                  path = pfad[0].toString();

           alias = requ.getParameter("alias").toLowerCase().trim();
..............


// Whats wrong there ? The Array is null. Not filled yet.
String pfad[] = requ.getParameterValues("proField");
//is right, but why is nothing transfered to it ?
