Excelsior JET 5.0 Slims Down the Java SE Runtime
Excelsior JET 5.0 enables Java developers to omit the unused parts
of the Java SE platform when deploying their optimized applications.
The new deployment model fully complies with the Java specification.
Novosibirsk, Russia, May 23, 2007 - Have you ever wished the JRE
was a bit smaller so as to bundle it with your Java application?
Excelsior JET 5.0, announced today, is the first Java SE
implementation that enables developers to leave the unused parts of
the platform out of their application installers. At the same time,
it maintains full Java compatibility through on-demand downloading
of the omitted at run time.
A Java SE implementation comprises thousands of standard API
classes, dozens of native method libraries and numerous data files.
However, most applications do not use some of the APIs at all.
For instance, an application designed to run in the background,
e.g. as a Windows service, may not need the Swing/AWT classes,
AWT native method DLLs, and the associated resources such as fonts.
The key new feature of Excelsior JET 5.0 is the ability to exclude
certain parts of the Java SE platform from the application's
installation package, thus reducing its download size and disk
footprint. For example, it may cut down a medium-size Java
application that does not use Swing or AWT to a mere 5 MB, whereas
the Sun JRE 5.0 alone is a 15 MB download.
Now, Java SE is a monolithic platform, as opposed to Java ME with
its configurations and profiles. How can a licensed Java SE
implementation allow you to exclude any part of the platform and
remain 100% compatible? Mr. Vitaly Mikheev, the CTO for Excelsior,
"When you build an installer for your optimized application,
Excelsior JET automatically creates a secondary package containing
the detached Java SE components. You place that package on a Web
server accessible to your end users, at the URL you have specified
in the primary package containing the application. If the
application attempts to access a detached component, the runtime
will download and unpack the secondary package."

technology are available at http://www.excelsior-usa.com/jetdownsize.
