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 ?
