Hi Sanjay,
I have the same problem.
ca.uhn.hl7v2.model.Message has no method to get the MSH segment until
you cast it to ADT_A01 ...
I found 3 ways to identify the message type :
* use reflection to invoke getMSH(), again to invoke
getMessageType(), and again for methods getMessageStructure() and
getTriggerEvent().
* use Terser :
Terser t = new Terser(message);
String triggerEvent = t.get("/MSH-9-2");
String messageStructure = t.get("/MSH-9-3");
Then you just need to write a long list of if(
"ADT....".equals(messageStructure) ) .....
* write the long list of if( message instance of ADT_...) ...
Hope it helps
Gabriel
