Yes I have only the 2.6 structures in my classpath. And Canonical should look
for 2.6 classes, however the stack trace says it's looking for 2.4 classes.
Everything is fine until I try to create the ACK. So I've used some duct tape
to get over the problem like this:
MSH requestMsh = message.MSH
def version = requestMsh.msh12_VersionID.versionID.value
requestMsh.msh12_VersionID.versionID.value = "2.6"
def ack = message.generateACK()
MSH ackMsh = ack.MSH
ackMsh.msh12_VersionID.versionID.value = version
Again, Groovy code, so don't worry about Java syntax.
