Easy deployment of JRE on Windows

Thread view:

Nikolaus Wagner - 21 Feb 2006 19:46 GMT

Hi!
I seek a solution to a simple problem:

An installer that just downloads the JRE if it is not present, installs
it silently and without any troubles.

Installing my program may then well be with a 15 MB JRE download
penalty (no problem with broadband) but there are no complications and
people might not even notice that they're downloading a java program
and the JRE, they should just notice that it took a while to download
my program.

So far I've only discovered the NSIS-Installation creator for Windows
on
http://nsis.sourceforge.net.

Is there a constant path for downloading the latest JRE on Sun servers
or is there a standard way of downloading the JRE?
An actual installer for Java on the Windows platform (and Linux,
possibly :-) would be fine too.

Thanks,
Nikolaus

the site says:
"It produces lightweight installers that can be run on any operating
system where a Java virtual machine is available. Depending on the
operating system, it can be launched by a double-click or a simple
'java -jar installer.jar' on a shell."

There might not be any JRE on the system - what I'm looking for is an
easy deployment of the JRE if that part of the software is not
installed - I do not think this is part of NSIS.

That is imho one of the deficiencies of Java on Windows: .NET gets
installed by itself, the Java runtime environment must be deployed
separately.

I would like to make that step as painless as possible.

With an ideal installation solution the user wouldn't even notice that
the app he installed is a Java app or that there is something
systemwide to install that does not really belong to the app itself.

Thanks,
Nik

You need to use it's "native launcher" along with IzPack.

At the bottom of the page at
http://www.izforge.com/izpack/index.php?page=download

I agree with you about requiting JRE to install a Java app on windows
or really any OS. I would think that Sun would update their JAWS to
handle this with a "very" small piece of C code.

there pretty well has to be because JAWS uses it and EMBED uses it.

At the very least JAWS knows.

JAWS can does almost silent installs of JREs.

presumably you dive at a get with that version param or some mangling
of it.

Maybe these in something in the JNLP spec about how it works.

No, sorry :-)

There is an old business program, written in Access 95 that I would
like to port to Java. There is almost no money involved, I'd like to do
this for fun, the money I may get will be spent on Java books ;-)
