Applet Security and Code Signing
Applets are contained within a security 'sandbox'. For obvious reasons, an applet can't execute malicious code on the user's machine (like reading or writing local files). However, there's a workaround. The latest browsers understand the notion of 'trusted' applets and allow those applets to work outside the sandbox. To make such a trusted applet, you need to digitally sign your code with a unforgeable digital ID which you can buy from a Certificate Authority. The browser will explicitely ask the user if he trusts applets signed by this ID before permitting it to do its thing.
