[HAPI-devel] resolving ca.uhn.hl7v2.model.v22.datatype.PN

[Phil S. <shi...@ya...>]

Hi all I'm new to hapi. I use eclipse to construct web apps and I'm working my way through
Developing using HAPI - By Example
Eclipse resolves most of the ca.uhn.hl7v2 libraries except the following;
ca.uhn.hl7v2.model.v22.datatype.PN;
ca.uhn.hl7v2.model.v22.message.ADT_A01;
ca.uhn.hl7v2.model.v22.segment.MSH;
I have the libraries in the build path but eclipse can't fing the classes PN ADT and MSH.At least that's what I think. What am I doing worong?Many thanks,Phil
