Re: [HAPI-devel] Hl7 over HTTP

[James A. <ja...@ja...>]

This should be fairly simple, it just means that you have a version of
slf4j-api that is too new (probably because HAPI is pulling it in). If you
explicitly add a dependency in your pom.xml for slf4j-api the specifies a
1.5.x version (you should be able to find one in your OpenHIE pom) it'll
use the older version.

You -might- need to actually explicitly do a dependency exclusion to get it
to not include slf4j-api 1.6.x.. mvn dependency:tree would help figure out
where that's coming from.

Cheers,
James
