About the Kernel Installer

Hi,

I really think the kernel installer has potential but there are two things I don't understand.

1. Why does the Kernel installer wizard not ask the user to restart his browser when the initial kernel + browser plugin is deployed? (it does not work if you don' t do that..)
2. Why does the Installer (updater?) not immediately start downloading the rest of the jre silently (maybe in system tray) instead of waiting for the first applet/jnlp?

In best case the whole jre is already installed before the user starts browsing, in worst case it is behaving like now and continuing to download stuff on demand ;-)

Also some users (demonduck) complained about the installer being not solid enough

what may be partly solved with the points above.

I also tried the installer and had to retry to load my rather complex* applet 3 times before it ran the first time (since than it worked always even after clearing the cash).

*uses shoal, jxta, scenario, swingx, two other jars and latest features like pak200 and draggable applet; signed

thanks,
mbien

mbien -- applet bummer...

java.lang.NullPointerException: name

That's what happened. I'm running 0.10rc and FF2 on Windows2000

well, the applet doesn't work with FF2 in general because the next gen plugin is the minimum requirement and AFAIK the new plugin won't be backported to FF2 (but that was not he point of the thread).
(i guess the old plugin does not know what to do with the "name" property which causes your exception)

It is a small monitoring applet for a cluster and it was tested on around 20 debian boxes, ubuntu and my xp notebook and it ran (most of the time) on them well.
