Hi Donald,

my apologies. I was thinking of the current development line (4.4) which supports Ice 3.3 and 3.4. In OMERO 4.3, you'll just need to make sure you import the file directly:

  import module_HPCService_ice

Do note, though, that when updating to OMERO 4.4 you might experience very odd Python import issues if you don't move to using IceImport.

Cheers,
~Josh.
