"No JRE version found in launch file for this system" and other assorted Java 6 crashes

Summary:

Is Java 6 ready for prime time?

Is it just my computer?

How come Borland/CodeGear is shipping Eclipse with a 1.5 JRE today?

There is no more enthusiastic Java supporter than me, but frankly,
Java 6 is taxing my patience: it just crashes and crashes. Nothing
seems to work under it. I must have reinstalled dozens of times.

I suspect that if I can solve just one problem, the rest will
(hopefully) go away.

Questions:

Can anyone of you folks out there run one of the most popular Java
applications, jDiskReport under Java 6 and JaWS?

http://www.jgoodies.com

Is there any change in JWS lately? There used to be a small
application with a set of programs and their status. The computer
would connect to the home of the JNLP program and get the latest
version. Now all I get when I double click on javaws.exe is a dialog
message.

For months, I have been patiently waiting for the next release of Java
6, but every single one shows the same symptom when I try to run
something: it gives me an error dialog that says:

More Information - Error: No JRE version found in launch file for this
system
Then, there are 3 tabs: "Launch File", "Main Launch File" and
"Exception"

This error message stays on the screen for about 3 seconds and then
disappears. The same vanishing behavior occurs if I try to use the
Java Control Panel to add a new JRE, or investigate which JRE is
actually being used.

Today, there was a miracle: the error message actually stayed on the
screen so I can transcribe the information contained in this post.

Oh yes: what's the deal with some version 6 cache which is flushed(?)
or updated(?) again, and again, and again...

I apologize for being vague, but I really would have to acquire a slow-
motion camera to get the disappearing messages.

I *really* would like to remove all instances of version 1.5 and byte
the Java 6 bullet (even modify my apps to make them v6 compliant) but
I am afraid nothing will work in my computer.

Any help is most welcome and appreciated.

This is the way to execute the "Java Cache Viewer", plus control panel
under Java 6:

C:\> javaws -viewer

So, that is one problem out of the way. But the crashing continues and
the rest of the questions are still open....

TIA!

Summary:

Yes, and it has been so for some time (IMO).
I started using it a couple of months ago, and the only problems
I have expereinced came from faulty Java (source) or JNLP files.
Is it just my computer?

I am suspecting as much.
How come Borland/CodeGear is shipping Eclipse with a 1.5 JRE today?

No idea. What did B/CG have to say on the matter?

http://www.jgoodies.com

Do you mean this one?

<http://www.jgoodies.com/download/jdiskreport/jdiskreport.jnlp>

Trying it here, on a Win XP Pro. box..
[console]
Java Web Start 1.6.0_02
Using JRE version 1.6.0_02 Java HotSpot(TM) Client VM
User home directory = C...
[/console]

[splash]
The digital signature has expired.
1.3.0
[WTE]
"JDiskReport enables you to understand how much disk space
the directories and files consume on your disk drives."
[/WTE]
'Next'
[/splash]
'Accept' terms of license
(choose some things)
See report on sub-dir of D: dirve.

Yep. It seems to work just fine in 1.6 here.
Is there any change in JWS lately?

Some minor ones, none that seem relevant to this problem.

...
More Information - Error: No JRE version found in launch file for this
system

Is that all web start? Check here ..
<http://www.physci.org/jws/version.html#enable>
..it is a page I wrote about enabling *earlier* Java versions,
but just check 1.6 is listed in the /JNLP runtime settings/
dialog.


BTW -
- where is this second JNLP file coming from? It has
nothing to do with JDiskReport, AFAIU.
