[HAPI-devel] Hl7 over HTTP

[Sara F. <sar...@gm...>]

Hi all,

I am working on sending hl7 message to OpenHIE <http://demo.ohie.org/> over
HTTP, I am using this example of HAPI.
<http://hl7api.sourceforge.net/hapi-hl7overhttp/doc_hapi.html>
Since I am working with hapi v2.0 I have changed the below line of code

> Parser parser = PipeParser.getInstanceWithNoValidation();          to

Parser parser = new GenericParser();

as it was added only in v2.2.
However I am still not getting a successful result. At the below line I am
facing an exception,

> HohClientSimple client = new HohClientSimple(host, port, uri, parser);


Exception:

with [1.5.5, 1.5.6]

Could someone guide me how I could overcome this error?
