Java and JavaScript are two different entities, but their source code
can look similar. JavaScript functionality is much more limited; I
don't know if it would be possible to get useful TCP/IP data streams
working with JavaScript alone. You'd get much more functionality out
of a Java applet.

Most desktop web browsers have JavaScript capability built in, but the
user may disable it. Your web page should be able to provide some
minimal functionality even if JavaScript is disabled, even if it's just
a diagnostic message asking the user to turn JavaScript on.

In order to use all the functionality of a Java applet, the user must
have a Java Run-time Environment installed. Microsoft used to include
its own JRE implementation along with Windows, but Sun put a stop to
that. So, any web pages that use Java applets now require that the
user must have an external JRE installed. JREs are available that will
work with all major web browsers of all popular operating desktop
systems.

Thank you
Information is useful.
JRE implementation is no more a part of Windows then my product user
will have to install JRE if I think to use Applets for real time data
update.
Purpose of making installable "device monitoring tools" web sever
base is to get rid of installable components and versioning issues.
Instructing customers to install JRE is not a good option.
can there be good alternate way to implement Real time web page ?

Whoa - hold on one second. Which part of your system is embedded - the
server or the client? Both?

If, as I presume, your server is the embedded side, all you need is a
socket. The Java etc stuff is for the client, presumably running on a PC
(else why use http at all?). The Java on the client is there to provide a
means of connecting the socket comms with the DOM on the page.

Or am I missing something?
