************************************************************************ Default handler for OPeNDAP .html requests.

getWebFormDDS

public opendap.dap.DDS getWebFormDDS(String dataSet,
 ServerDDS sDDS)
                              throws opendap.dap.DAP2Exception,
opendap.dap.parsers.ParseException

************************************************************************ 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:

opendap.dap.DAP2Exception

opendap.dap.parsers.ParseException
