Solution
Sun's Java Web Start combines browser-based ease of use with applet-like “sandbox” secur-
ity (which can be overridden on a per-application basis) and “instant update” downloading
but also lets you run a full-blown application on the user's desktop.
Discussion
Java Web Start (JWS) provides application downloads over the Web. It is distinct from the
old Java applet mechanism, which required special methods and ran inside the browser
framework. JWS lets you run ordinary GUI-based applications. It is aimed at people who
want the convenience of browser access combined with full application capabilities. The user
experience is as follows. You see a link to an application you'd like to launch. If you've pre-
viously installed JWS (explained toward the end of this recipe), you can just click its Launch
link and be running the application in a few seconds to a few minutes, depending on your
download speed. Figure 21-6 shows the startup screen that appears after clicking a Launch
link for my JabaDex application.

After the application is downloaded successfully, it starts running. This is shown in slightly
compressed form in Figure 21-7 .
