[HAPI-devel] Problem sending HL7 over HTTP

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

Hi all,

I am trying to send HL7 message over HTTP using this example
<http://hl7api.sourceforge.net/hapi-hl7overhttp/doc_hapi.html>. I have
changed the below line to Parser parser =
PipeParser.getInstanceWithNoValidation(); to
Parser parser = new GenericParser(); as I am working with HAPI 2.0.

I have added the below dependency also.

<dependency>
   <groupId>ca.uhn.hapi</groupId>
   <artifactId>hapi-hl7overhttp</artifactId>
   <version>2.2</version>
</dependency>


However at below line I am getting an error.

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

Error is:

SLF4J: The requested version 1.6 by your slf4j binding is not compatible
with [1.5.5, 1.5.6]
SLF4J: See http://www.slf4j.org/codes.html#version_mismatch for further
details.

I tried adding exclusions but that didnt help,
<dependency>
    <groupId>ca.uhn.hapi</groupId>
    <artifactId>hapi-hl7overhttp</artifactId>
    <version>2.2</version>
    <exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
<exclusion>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
</exclusion>
</exclusions>
</dependency>

Could someone guide me where I could probably be going wrong in using this
example?

Thanks & Regards
