Auto download of jre with jws 1.2

Question

We use JWS for downloading JRE from a local server, (using the concept proposed by T.Dunst http://www.vamphq.com/jwsfaq.html#ownj2se). Our Installer class is based on Dale Searle's Java Runtime Installer (also found on above link), including his hack for using the same downloaded jre for all users.
This works fine with jws1.0.1, which stores the downloaded jre in an extension directory in the Java Web Start installation directory.
Problem is that now that we upgraded to JWS1.2, jws default location for the extension directory is in the users profile, and thus it can't be accessed by all users.
Anybody have an idea of how to solve this?
On code level the difference is that, considering the following code in my Installer class:
private static String installPath;
private static ExtensionInstallerService service;
service = (ExtensionInstallerService) ServiceManager.lookup(
"javax.jnlp.ExtensionInstallerService");
installPath = service.getInstallPath();
for JWS1.0.1, installPath will be the path to Java Web Start directory
while for JWS1.2 it will be the path to the User Profile.
My first idea to solution was to just set the value for installPath to the path to Java Web Start directory, but I don't know how to get this information using JWS1.2. Anyone else knows?

Answer 1

However, I don't see how it solves my current problem with one
download for all users on the same machine. Unless I'm misstaken,
using this Web Start Service Pack with JWS1.2 will still store the
downloaded jre in the users profile and it will thus be unreachable
for other users, right? If you want to discuss the Lopica Web Start Services Pack I invite you to join the lopica-talk mailing list @ http://lists.sourceforge.net/lists/listinfo/lopica-talk
I'm not the author of the package and, therefore, can't answer your question. Please, ask Richard on the lopica-talk mailing list how you can adapt the package to your needs.
