check if file exists

[lowbk]

how to check if a file exists before writing it to the server?

in case that is not clear, i have a form written in jsp, when user clicks the "save" button after filling in the form and specifying a filename, servlet will create the file and write to the server. thus i need to check the existence of the filename.

i tried using the File object but i think it is for Netscape and it doesn't use URL path.

any kind sould pls advise

Hi lowbk,
I dont think that u can access client machine to check whether the file exists which the user wants to upload to ur server through HTML/JavaScript. You will have to download an Applet to client browser if u want to access his machine.
O !!

lowbk, you can intergerate the filesystem from javascript using the fileSystemObject()

you can minuplate files , folders, drivers and more.
