What are the security limitations of a Java applet in a Web browser?
Java was developed with the intent to prevent applets from inspecting or changing files on the client file system, or from using network connections to circumvent file protections or people's expectations of privacy.
What this means for developers is that your applet will only be able to read to and write from a file on the server that the applet was served from. Using Sun's appletviewer, however, you can specify which files on your PC may or may not be read/written by an applet or application. This may be fine when you are developing applets for you or your companies use, but it won't do much for you if you are developing applets for the Internet.
The JDK 1.1 provides the ability to load and authenticate signed classes. This enables browsers to run trusted applets in a trusted environment, but as of yet most browsers do not support the JDK 1.1.
