[MOBY-l] request about getNamespace() in MobyData

[RE BARBARA]

Hi,

once extract the input of a service (through the Bees java), as can I do for 
extracting, for examples, the Data Type or Namespaces?

I don't succeed in using the method "getNamespaces()" or "getDataType()"  
because the method getPrimaryInputs() returns me a type MobyData while the 
methods "getNamespaces()" or "getDataType()" require MobyPrimaryDataSimple.
  
How can I do? 

Barbara
