TimYates,
You're simply Amazing!!! there's a small issue I think it is because we are using the same recordset when we sort the tag lib (click the header) the combo also follows the sort order, i've tried to change/create another stmt
not sure if this is the right way to go...
Thanks

I would read all of your combo options into a List then, use this list to build up the Select...
Hmmm... try (not compiled -- hope it works):
<%!
// Define a class that will hold our id->name pairs for the select box...
public class ComboItem
{
int id ;
String name ;
public ComboItem( int id, String name ) { this.id = id ; this.name = name ; }
}
%>

Class.forName("com.mysql.j
connection = DriverManager.getConnectio
ResultSet rs = stmt.executeQuery("SELECT ID,Name from employees");
RowSetDynaClass resultSet = new RowSetDynaClass(rs, false);
rs.beforeFirst() ;
// make a list for our id->name pairs:
java.util.List selectData = new java.util.ArrayList() ;
// Load the id->name pairs into a list
while( rs.next() ) {
selectData.add( new ComboItem( rs.getInt("ID"), rs.getString( "Name" ) ) ) ;
}
request.setAttribute("resu
%>
<select name="combo">
<%
// Fill the combo from our list :-)
for( int i = 0 ; i < selectData.size() ; i++ )
{
ComboItem item = (ComboItem)selectData.get(
%>
<option value="<%= item.id %>"><%= item.name %></option>
<%
}
%>
</select>

>> <option value="<%= rs.getObject("ID") %>"><%= rs.getObject("NAME") %></option>
I *think* something is wrong with the quotes here...
