After making some changes the RDS_R06 class is loaded but not the PFG custom
Group. I tried different package arrangements for the PFG group but it never
got loaded. I notice in Ian's example he extends from class ORU_ORMIS, whilst
I'm extending from AbstractMessage. I see that as the most significant
difference in my approach. Other than extending AbstractMessage I'm not aware
of which standard class to extend from.
This is the structure of the code :
com.lds.hl7.zxx.custommodel.v25.message
RDS_R06 , this is the custom message class
com.lds.hl7.zxx.custommodel.v25.segment
ZR2 , this is a custom segment
Other segments etc. are also present in this package but omitted.
com.lds.hl7.zxx.custommodel.v25.group
PFG
