thredds data viewer

Hi

I tried launching thredds data viewer using webstart. vierwer was launched
but i couldnt connect to any test catalogs.

it gave me error :
invalid catalog <..path..>
catalog validation version 0.6.02

Inv Catalog Factory.readXML (2) can't open catalog; response = 404 not
found

Connection is not established///

Also i downloaded zip file for installing thredds data viewer (it has all
jar files) and there is no documentation on how to install it. Am i
missing out anything ?

Bye
