Do I need to change my application to work with JavaTM Web Start?
If your application is written to the JavaTM 2 platform, and is delivered as a set of JAR files, there should be no need to revise your application. Make sure that all your application resources (such as images and resource bundles, for example) are retrieved from a JAR file, since JavaTM Web Start launches an application by invoking the public static void main(String[] args) method. And if your application needs unrestricted access to the system, (for example, network or disk access), you will need to sign your code.
