Adding my 2 cents...
I stuck with the Java Object-Oriented way (I like compile-time checks and my
IDE's auto-completion), and wrote conversion methods to our classes for
Segments and Data Types. I end up having a Message method for each unique ADT
message, but they are all VERY short. All the

Hi Steven,
The model actually is- There is an ADT_Axx Java type for each HL7 message
type, which has all of the segments in reusable Java types as well. The
method suggested below by Laurent (and others) is taking advantage of that

Forgot to mention that you currently still need to include the
hapi-structure jar(s) in your classpath, depending on the HL7
version(s) you expect. You can also use the CanonicalModelClassFactory
with your parser, then you only need the latest structure jar.
In HAPI 2.1 (not released yet), you will
In general, you don't have to cast to a specific message structure
class: the parser returns a Message object, and you can obtain
segments using message.get("segment-name") , and from a Segment you
can obtain a field using segment.getField(field-number). If that's not
generic enough, take a look at
Hello,
I am new to HL7 as well as it's contents. I hope this question isn't too
stupid.
I'm trying to read from messages generically - is there any way to grab
particular segments without having to cast the Message object into ADT_A05
for example? I could have various ADT_* and trying to find the
13 matches
