Figure 4 The JARDiff working mechanism. http://ptgmedia.pearsoncmg.com/images/art_marinilli2B_jnlptutorial2/elementLinks/marinilli2B_fig04.gif As discussed, the JARDiff format is a way to perform incremental updates to a JAR file. It consists of a special JAR file sent to the client, which describes the differences between two JAR files—OldJAR and NewJAR, for example. The differencing information is stored in the META-INF/INDEX.JD text file, which describes the copies of new or changed files in the NewJAR file relative to the OldJAR file. The file is composed of lines space . The first line describes the JARDiff format version (currently 1.0): version And following are lines of two types: remove move . They describe the differences between the already installed OldJAR file and the to-be-installed NewJAR file. The following sections summarize the pros and cons of using JNLP. ~ Perhaps those mobile apps are so small and selfcontained that jardiffs don't make any sense.

When I look at a smartphone or iPad screen showing "apps", it very much reminds me of a web page showing icons, under which hide java "applets"; and when you click one of these "apps", a piece of code starts running and takes over the screen. Now what this "app" does, is another story. It could be self-contained and not communicate with anything else, like a tic-tac-toe app or a calculatro app. Or it could be that it needs to communicate with some server on the Internet in order to be useful (like an airplane reservation app e.g.). In that case, it needs to use a communication protocol in order to talk to that server, and that communication protocol could be HTTP and that server could be running Tomcat. Now from the Tomcat point of view, whether the client talking to it is an app or a browser or anything else which properly talks HTTP should not matter. Unless you are talking about setting up some kind of "app store" and using Tomcat to do that ? but in such a case, the issue would not be about Tomcat, but about creating an "app store webapp" running under Tomcat. Or ? I have the feeling that something fundamental may be escaping me here, but for now I am still puzzled. [OT philosophical section] Apps are "cool".
