Java SE (Java Platform, Standard Edition)

Hi

In the following line in the my jnlp I presume that the href tells Webstart where to find resources for installing the spefic JRE if not already installed.

<j2se version="1.5.0_11" href="http://java.sun.com/products/autodl/j2se"/>

If I want to change that URL to an intranet address for faster installation, what do I have to place there? I tried the below and of course placed the cab file in that location, but it did not work. I guess the cab file is only for in-IE installs using an activeX / object tag in the HTML. What to I need to do to have it happen via webstart? I know that all my users (on the intranet) will have java installed, but many could have only java 1.4.2 so I want to build in this upgrade.

<j2se version="1.5.0_11" href="http://<intranet-address>/jinstall-1_5_0_11-windows-i586.cab"/>

Thanks,
Anthony

PS the application will run with any 1.5 JRE so in fact my JNLP j2se section would look like this:
<j2se version="1.5"/>
<j2se version="1.5.0_11" href="http://<intranet-address>/jinstall-1_5_0_11-windows-i586.cab"/>
