Hi All, I'm in the process of migrating a MySQL database from Debian to windows vista (localhost using Apache - installed and running via EasyPHP).

Hi, I am new to Swing and wish to implement the download file feature in my Swing code, that would allow the user to either save or open the specific file.

I want DWR to transparently batch all remote calls that are done in the course of handling the same event. The reason is that handling an event in Javascript must only take a short time and nothing else can happen during the same time. So if I am going to do many calls, I would like to DWR batch them transparenty. Is that possible? How?...

I'm coming up the learning curve for Swing and am reading about InputMap and ActionMap. The O'Reilly book on Swing says the keys for ActionMap can be any Object, but by convention are Strings. Is there any reason to use an object other than a String? (e.g. an enum) I would think it's bad practice to use String literals, as they can be ...
