Method for on-demand network application download and execution

摘要

Methods for executing an applet (310) is disclosed. A virtual machine (312) that includes a class loader (314) generates a file download request in the form of an http request to a particular server computer (304) that contains appropriate applet component files. The class loader (314) queries a root JAR file having an index file (316) associated with applet. The class loader (314) creates a HASH table (318) based upon the contents of the index file (316) that provides a mapping of all packages and all corresponding JAR files required to execute the applet (310) by the virtual machine (312). During virtual machine runtime the class loader (314) queries the HASH table (318) in order to directly access the appropriate applet component file to be downloaded and executed by the virtual machine (312). <IMAGE>
