The Applet Class Loader is a crucial component of the Java security architecture, specifically designed for loading Java applets from the internet into a Java-enabled web browser. When a web browser encounters an <APPLET> tag within an HTML document, the Applet Class Loader is responsible for dynamically downloading the corresponding Java class files from the specified URL and loading them into the Java Virtual Machine (JVM)[1].
The primary function of the Applet Class Loader is to place these applets into a private, secure namespace, preventing them from interfering with the operation of other applets or accessing restricted resources on the host system. This isolation helps maintain the security integrity of the web browser and the underlying system[8].
Moreover, the Applet Class Loader enforces strict security measures by integrating with the Java security manager, which imposes a set of restrictions on applets to prevent potentially harmful operations. These restrictions include limiting access to the local fi...
