java application install on windows

[rodinw]

Hi,
I wrote a java application and hen I distribute it to users, I put the
jre which includes all the necessary library and exes. Now I wrote some
other applications, when I distributes them, I did the same. The
question is, if a user uses more than one of my applications, he will
have multiple jre directorys on his hard disk. How to avoid this? It's
not practical to ask them to download Java themselves first.
Please give some advice.

Your installer can include the installer for the java plugin. You could
unpack the installer to a temporary directory and than install it,
possible withouth user intervention, by using silent installation.

You can do a silent install of Java.
