************************************************************************ Gets a DDS for the specified data set and builds it using the class factory in the package opendap.servlet.www.

Currently this method uses a deprecated API to perform a translation of DDS types. This is a known problem, and as soon as an alternate way of achieving this result is identified we will implement it. (Your comments appreciated!)

Parameters:

dataSet - A String containing the data set name. 3 * @return A DDS object built using the www interface class factory.

Throws:

DAP2Exception

ParseException
