What I would do next is to download and run the development version (3.3), 
which will give you an error message instead of throwing an exception. A number 
of other bugs are fixed and we are on the verge of making it the stable release.

get latest thredds.war from 
http://www.unidata.ucar.edu/projects/THREDDS/tech/index.html#TDS

also, get Remote Management working by following this page:

 http://motherlode.ucar.edu:8080/thredds/docs/RemoteManagement.html

there are various debugging things that will help. If you give us a password, 
we can help you debug remotely. (but i will be gone all next week).
