Hi Mark, MSH-9 is slightly misformatted - this causes HAPI to skip creating the MSH segment and therefore no MFN_M15 but a ca.uhn.hl7v2.model.GenericMessage$V25 is created and you get the ClassCastException.
Simply replace |MFN^M15^MFN M15| with |MFN^M15^MFN_M15| (note the underscore instead of the space) and everything works. cheers Christian Mark_Huang wrote: > > I am new to HAPI API, and try to get the repetitions of MF_INV_ITEM of > MFN_M15 message. > > 1.
