RE: [HAPI-devel] Message Casting Error

Hi Matias, 

Yes, that's probably it.  As Martin said a few minutes ago, it sounds like
Terser is your best bet.  It automatically accounts for differences between
versions.  By the way there are some examples of Terser use in
DefaultApplication: 

http://cvs.sourceforge.net/viewcvs.py/hl7api/hapi/ca/uhn/hl7v2/app/DefaultAp
plication.java?view=markup

... see makeACK() and fillResponseHeader() for different styles of use.

Subject: [HAPI-devel] Message Casting Error

Hello,

I've just started testing HAPI v0.4.1.  I'm trying to cast a Message
object to an ADT_A04 object.  Here is my code:

public ADT_A04 convertMessage(Message in){
	ADT_A04 adt = (ADT_A04) in;
	return adt;
}

When I pass an ADT_A04 message to this function, I get the following
error:

java.lang.ClassCastException
         at com.test.HL7.processors.ADTProcessor.processMes
age(ADTProcessor.java:67)
         at 
ca.uhn.hl7v2.app.MessageTypeRouter.processMessage(MessageTypeRouter.
ava:52)
         at
ca.uhn.hl7v2.app.Responder.processMessage(Responder.java:159)
         at ca.uhn.hl7v2.app.Receiver$Grunt.run(Receiver.java:115)

What would cause this considering that the message being passed in is an

ADT_A04 message?  Could this be a versioning problem (i.e. the message 
is v2.4 and the ADT_A04 class is from the v2.3.1 model package)?

Thanks,

Matias
