That's very stange because it works very well for me...
Do you apply the getNames() on a
ca.uhn.hl7v2.model.Message
or on a
for example : ca.uhn.hl7v2.model.v25.message.ADT_A09
Maybe, as the message structure is known, in the second one, it returns
the segments that should be found in the message, but in the first the
structure is unknown so it can just return what's really in the message.
Try a cast to a "Message" you'll see...

Thanks..but getNames() returns all the segments that should exists in
the message..not what is currently present in the message. Calling
getNames on an ADT message returned the following structures
MSH,EVN,PID,,PD1NK1,PV1,PV2,DB1,OBX,AL1,DG1,DRG,PR1ROL,GT1,IN1IN2IN3,ACC,UB1,UB2
and my message only had MSH and PID.

message
Hi,
One way, but perhaps not the best (???), could be this:
String[] segNames = hapiMessage.getNames();
Then jsut browse your string array to find if your seg exists
Hope it helps
Bye

Great question, I would also like to know if there is a way of doing this.
Right now I need to check each element for null.

How can I check if a segment is present in a message..when I do the
following code it always returns a value then if I read a field the vlue
is null..very similar to if it was there...how do you know the
difference
PID seg = (PID) hapiMessage.get("PID");
if ( seg == null)
return false;
else
return true;
