I need to do this in a web application (using jsp's, servlets, applets),

From a client machine select some text files located in a server machine and send them through client serial port (not server serial port) to a handheld computer.

How can i do this?

You'll need to use a signed applet and (maybe Javax comm) although try to avoid the latter by opening a FileOutputStream on "COM1"

Why do you need to send them through the serial port? Are you connecting the handheld to your computer?

You can't without installing javacomm or equivalent on every client.
