Dependency issue in NWDS 7.3 SP07

Hello,

I am trying to use some standard classes from software components ENGFACADE and BPEM-FACADE in my NWDS 7.3 development. I have set corresponding dependencies to these SCs and set the dependncy properties also (Design Time, Runtime, Deploy Time). I am trying to use the classes/interfaces such as ProcessDefinitionManager, ProcessDefinition, IUser etc, but for some reason it is not getting resolved or imported into my application even if I do "Organize Import" in WebDynpro perspective. Any idea why is this happening?

Screens attached for reference

Thanks in advance,

Mansoor.
