You could use the GNU java compiler which produces native code from
java input. It is available through the cygwin package
(http://sources.redhat.com/cygwin).

If your user base is all Windows, why not
program in .NET?

Alternately, if you might like to target Mac
or Linux/Unix machines as well, why not
install using web-start?

I have not learnt .net.
and I have write some programs in java
but what bother me is that not everyone has installed JRE
and they will not try it.
so I want to turn it to native code.

C# is pretty similar to Java such that you can pick C# pretty quickly,
if you already know Java. There are also compilers which take Java source
code and emit .NET binaries, but you can't use most of Sun's class
libraries, as they won't be available in a .NET environment. Instead,
there's a pseudo-equivalent called the GNU ClassPath, I think.

.NET isn't native code either, but I bet Microsoft is going to make sure
.NET gets bundled with every copy of Vista.

Instead, you expect everybody to install Windows?!?

I know of more people who 'would not let Windows
infect a PC' than either know or care about the
existence of Java.

This 'program for everybody' is an illusion.

Get over it and concentrate on providing
'the working prgoram - or clear steps about what
to do to get to get the working program'..
then encourage your end-users to recognise
that the best way to run your program is with
an up-to-date Java Plug-In.

Hi,

try a program like JSmooth (http://jsmooth.sourceforge.net/).
It packs your .jar and optionally the JRE in an .exe-file so that you
can run it very easy.
But this is only a wrapper for your .jar, it doesn't transform it to
native code.

Andy

You should look at reading 'Write Portable Code', Brian Hook, No Starch
Press, 2005. It does not have java examples but the book does
elucidate certain portability issues that you are going to run into --
especially if you plan to utilize the gcj compiler.
