Building dynamic URLS in jsp

Question

Hello,
I wonder if you could help , please.
I have prepared a JSP page which has three different combo boxes.
Depending on the option chosen , I have to submit the form to an html page that it is located in a different server.
So I have to make the url to that server but with the value chosen in the last combo box.
I mean , in another server in the address (http://www/ejemplo.com/test/)I have pages like :
a1.html
b2.html
c1.html
Where a1, b2 and c3 are the values chosen in the last combo.
I have an input button , and when it is clicked , it should forward to the address:
http://www/ejemplo.com/test/a1.html if a1 were chosen.
I have written teh following code, but it does not work....How can I do it??? Could anybody help, please???
<INPUT TYPE="submit" name="Solicitud" value ="Request Page" >
<%
if ( request.getParameter("Solicitud") != null )
String pagina = "http://www/ejemplo.com/test/" ;
String sel3 = request.getParameter( "Combo3" );
pagina = "pagina" + "sel3";
pageContext.forward(pagina);
}%>
</form>

Hi Ani,
First of all, you were correct , I forgot to include the .html for the option chosen in the combo3.....I have corrected it..but still does not work....
Do you have any idea???
Here you have my new code...
<INPUT TYPE="submit" name="Solicitud" value ="Request Page" >
<% if ( request.getParameter("Solicitud") != null )
String pagina = "http://www.ejemplo.com/test/";
String sel3 = request.getParameter( "CountryCode" );
sel3 = sel3+".html";
pagina = pagina + "sel3"; //removed the quotes for pagina
%>
<jsp:forward page="<%=pagina%>">
</jsp:forward>
<%}%>
</form>
