Hi Ram,
You might have a look at the Terser class, which can help you populate
messages in a more generic way:
http://hl7api.sourceforge.net/xref/ca/uhn/hl7v2/examples/ExampleUseTerser.html
One thing to note is that the structures are backwards compatible (this is
a feature of the HL7 standard itself, not just of HAPI). Each new version
adds fields to the end of segments, adds segments to messages, and
deprecates certain parts of existing structures, but does not fundamentally
alter the structures. You could actually just use a v25 structure to create
a v23 message for example, so long as you:
1. Set the MSH-12 (Version) value to "2.3"
2. Use care not to populate fields/segments in the 2.5 structure that are
not used in the 2.3 equivalent.
Cheers,
James

All the data continuously generated in your IT infrastructure
contains a definitive record of customers, application performance,
security threats, fraudulent activity, and more. Splunk takes this
data and makes sense of it. IT sense. And common sense.
