It sounds like you might be working too hard :-).
Internally, Java keeps all String values in Unicode. When you actually
write the response, it will be converted according to the character
encoding you specify on the page.
If you're using JSP you would put this at the top of your page:
<%@ page contentType="text/html;charset=Big5" %>
and then write out the values something like this:
<%= sb.getItemname(itemid) %>
>From a servlet, the important issue is to set the content type and
character encoding *before* you get the PrintWriter:
response.setContentType("text/html;charset=Big5");
PrintWriter writer = response.getWriter();
...
writer.print(sb.getItemname(itemid));
In either case, Java will perform the Unicode->Big5 conversion for you.
