Re: [HAPI-devel] Query about a problem.. .. ..

[Nico V. <ni...@us...>]

Hi Latha,

Could you please share the hl7 message you're trying to parse ?

I guess that your problem is related due to the fact that the segments 
(OBX...) are part of a segment group.

Please check the readme.txt file in the HAPI cvs root folder for 
instructions on obtaining the source code for the generated classes.

Thanks a lot !

Regards

Nico
