Hi
place the selected value or index in a hidden text box or in a variable and then assign it to the select box using javascript. this gets selected when the values come from the d/b into the second select box.
Hope this helps u.

Hi devender
As I can understand you submit from first page having a listbox(first) , you have to get this in the second page which has second listbox with the current selected value as the one you just selected.
try this in second jsp

 
String selectedStr=request.getParameter("firstlist");// firstlist is the name of the first list box
out.println("<select name=\"secondlist\">");
/*
Perform the sql operation and select from the database let us assume into Resultset rs
*/
String curval="";
while(rs.next()){
curval=rs.getString("colname");
out.print("<option ");
if(curval.equals(selectedStr))
out.print("selected");
out.println(">"+curval+"</option>");
}
</select>
 

I thing this is what you wanted.
