    Default Re: autocomplete using ajax

    Hello, what bit of your whole requirement is it that you have a problem doing, it sounds like you want help to do the whole thing and as far as I can see its databases, struts, javascript and jsp all in one, try starting some of it your self and once you get stuck tell us what exactly you are stuck on as that's more likely to give you a positive response.

    At the moment I don't really know where to start helping you, sorry.
