Instead of trying to send the JAR down you should rather URLClassLoad your application using the URLClassLoader class, see: http://java.sun.com/j2se/1.4.1/docs/api/java/net/URLClassLoader.html.
Unforntunately I no longer have a code snippet to illuistrate this, but the basic technique is as follows, you manually deploy (once only) a litle 1K launcher program to all your clients, this in turn URLClassLoads the main class of your application, the rest of the application will automatically URLClassLoad itself as all additional classes will be loaded with the same class loader. Now if any classes are changed in your application then the next time any user runs the app they will run the new class. Note that if you need to change the launcher program this needs to be manually re-deployed. However once it is working you rarely need to change it.
