See the following page on how to "flush" environment variable changes so they are available to other applications: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/environment_variables.asp.

We are using jRegistryKey and we wrote wrappers around it to provide easy registry path manipulation. The problem with using Java to manipulate the registry is that we haven't found a way to flush the changes like you can with InstallShield, etc so they are available immediately. Thus the user has to go flush them manually by going into the env var dialog and hitting ok, or you have to request a reboot.

Subject: Re: Ant Featured in Out-of-the-Box
On Windows, we use InstallShield to initially drive the installation,
call out to other Windows installers (e.g., JDK, Apache, MySQL, WinCVS,
etc.), update the registry as needed, and finally kick off our master
Ant script to do the bulk of the installation (e.g.,
extracting/decrypting/copying/moving files, regex replacements, CRLF
fixes, calling other Ant-based installs, running JUnit/HttpUnit,
processing XML docs with XSLT, creating/updating properties files,
creating and populating databases, building and deploying J2EE apps,
etc.). There are actually one or two places that we have Ant call Java
code to create/update some Windows environment variables via JNI, but
it's fairly simple and well-contained.
On Linux, we use Ant to do it all because there's no need for registry
manipulation. We have Ant ask the user for input up front (e.g., where
to install, DNS setup, user ID/password, etc.) then do all the rest
without further user interaction.
so what you are saying is we need a <regedit> task for java, which creates a
regedit file and then execs regedit. An interesting thought...
