Question

Have to create a JSP with a Combo box and couple of Text fields. Depending on the Selection of the Combo box the text fields get populated. All the data is coming from the database.
Cannot create different pages for Combo box and the Textfields, they are part of a single form.
Need some help in terms of how to implement this.
Thanks

It's a JSP, just add an onchange event to your drop down box which will submit the page to something (like itself) and based on that value on your jsp get the data you want and display it.
<%!
     public String[] getFields(String selectedMode) {
          if(selectedMode!=null) {
               return SomeClass.getFieldsFromDB(selectedMode);
          return null;
%>
<%
     String mode = request.getParameter("mode");
     String[] fields = getFields(mode);
%>
<form name="foodForm">
     <select name="mode" onchange="foodForm.submit()">
          <option>Select a type of food</option>
          <option value="Fruit">Fruit</option>
          <option value="Vegetables">Vegetables</option>
     </select>
<%
     if(fields!=null) {
          for(int i=0;i<fields.length; i++) {
               //do something with these fields
