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
Sara Fatima
