I got this jsp example from the internet but the problem is that, it can not show some fields like firstname, lastname, address etc. To my surprise again it can show fields starting from state downwards. So i was wondering if you could help me figure out the problem.

 <% @ page import="java.util.";%>
  <% @ page language="java"%>
   
H <HTML><HEAD><TITLE>Dynamic Form</TITLE></HEAD>
  <BODY>

  <%  String[] textFields = {"FirstName","LastName","Address","City","Zip"};
     for(int j=0; j<textFields.length; j++){     %>
     <TR>    <TD> <%=textFields[j]%>:                       </TD>

  <%  String[] states = {"AZ", "CA", "NM", "MA", "ME", "MD", "..."};
      for(int s=0; s<states.length; s++) {    %>

Also you cannot ensure the order of the parameters being submitted .
You have to use something like
  if (parameterName .equals("param1"))
<TD><%=parameterName%></TD>
            <TD><%=parameterValue%></TD>

}
