Fast rendering of unsigned applet jars in a web browser environment

摘要

A system for fast rendering of an applet in a Web browser environment. A server process pre-determines the order in which the applet classes are loaded by the applet. The server process determines the classes of the applet that are required for applet start-up, and these startup classes are bundled into an initial JAR file on the server for the applet, along with a list of other class files belonging to the original JAR files. After the initial JAR file is downloaded, and while the JVM on the client system is loading the applet classes from the initial JAR file to bring up the applet, the rest of the applet classes (i.e. non-startup classes) are downloaded from the server to the client in the background. As each such non-startup class is received by the client system, it is loaded into the correct JAR file based on the class list.
