Maxim Zakharenkov leads a small team developing Swing applications
with remote backend. The applications combine both client
and server side giving a great opportunity to work with multiple
client and server technologies. He believes that the best way
to program remote desktop applications is to use Java both
on client and server side instead of bunch of different technologies
like HTML, JavaScript, Ajax, XML, JSP etc. Maxim hopes
that people will finally stop fighting with Web browsers and related
stuff and return back to old and simple Java applets or similar
newer things.
