Error: package oracle.epm.fm.webserviceproxy.datatype does not exist

I am trying to write a script to load data from a flat file with the Customization Kit Sample supplied by Oracle  for HFM Java API.

But as soon as I open the project I am missing a package. And I do not know where is the library JAR supposed to supply this package : Oracle.epm.fm.webserviceproxy.

What JAR/Library am I supposed to import in the project for this package to be imported?
