Can anybody give me a push in the right direction

If your applet is running in a browser you won't be able to touch files even on your local machine. Unless you are trying to communicate over a network to a remote database.

Good Luck

hi, u cant use jdbc with an applet as it accesses ur hard disk (which is no permitted). servelets should b a good choice. bu i've seen a way to read the secure files in the hard disk using a method called 'digital signature'. read 'bout this in some book (java unleashed is useful). u can actually sign ur class files digitally, so after it is approved by the system, ur class can read the secure files like autoexec.bat. i dunno if its the same 4 databases.

luv
Karthik.
