Hi Venu,
Yup, Patrick pretty much sums this up. HL7's batch protocol is kind of a
strange beast, and isn't currently supported out of the box by HAPI.
That said, it probably woudn't be terribly difficult to add support to the
MinLLP implementation, as it is (as Patrick points out) basically just an
enhancement to the message wrapper that happens to look like the message
payload it carries. If you were interested in trying to implement it, Id be
happy to point you in the direction of the classes that need modifying.
Cheers,
James
