Gah...This was annoying... Glassfish 3.0.1 on Vista...

I have some time off... So I decide to check out Glassfish 3.0.1 (yes that is very geeky), it should be a nice new toy even with and evil red logo on it now. I am quite fond of glassfish, it was a pleasure to work with as a developer. I had spent a good almost 2 years using and fighting for the use of Glassfish 2.1 / OpenESB or Glassfish ESB... and lost the month I decided to get married and go on honeymoon...
That is probably lesson in itself, with some kind of motto:Never go on leave

.... anyway ....

Back to my current annoying discovery:
I try start up Glassfish after the install... (in Netbeans 6.9) and it fails with a silly little error:
"Address family not supported by protocol family: bind: 7676"
and then proceeds to shutdown..

So off to google...
Read quite a few useless forum posts...
Eventually find the below... pay it no attention of course... and carry on reading useless posts...

Hi,

Try to change configuration of localhost in file
C:\Windows\System32\drivers\etc\hosts
from
::1 localhost
to
127.0.0.1 localhost
"

After another couple minutes, I decide "what the hell", and I go find the host file, make the change...big surprise... Windows doesn't let me.
Download "Unlocker", pretty neat utility if you want to overpower the Windows file locks, but it picks up no lock.
Another trip to google.... Only to find you need to run the edit application as an administrator obviously...

Make the change, and Tah Dah! Nice new Glassfish 3.0.1 server up and running.
