As shown on http://hl7api.sourceforge.net/v25/apidocs/ca/uhn/hl7v2/model/v25/message/ORL_O34.html the definition of the message in the the 2.5 jar does not match the definition in the standard. The group "Response" is missing in the definition of the message. See HL7 V2.5 Ch4 page 4-20
This is probably due to an error in the database during the generation of the classes. I just wanted to make you aware of the problem.

That's right. There has to be a ORL_O34_RESPONSE group around the ORL_O34_PATIENT group. ORL^O22 does it right. James, can you check the DB?
This has been fixed and checked in. Thanks for reporting!
