Hi Chandan,
There are two good ways of doing this: you can use the Terser, which
involves something along the lines of
String version = new Terser(yourMsg).get("MSH-12");
or you can use the CanonicalModelClassFactory
<http://hl7api.sourceforge.net/base/apidocs/ca/uhn/hl7v2/parser/CanonicalModelClassFactory.html>
and configure it to just always use the highest version of HL7 you want to
support. This is my preferred approach personally, and it works well
because HL7 structures are basically backwards compatible (they add things
and deprecate things, but they never remove anything).
Cheers,
James
