I have received this request a couple of time and thus I have decided to post a blog in order to explain how to do it. 

Hapi provides a test panel app that allows a user to easily use the library in order to send or receive HL7 messages. That GUI provides a check box for using TLS.

The IHE ATNA profile requires mutual authentication, this means that the client AND the server need to provide a certificate in order to reach successful TLS negociation. Checking the TLS box does not tell hapi which certificate to use. 

What most people are forgetting is that they need to configure Java to tell what certificate to use when initiating the TLS communication and what certificate to trust. In order words, the user who would like to use TLS, needs to provide java with the pointer to the truststore (list of certificate to trust) and the pointer to the keystore (certificate to use to initiate TLS).

The easiest way to do it without breaking the entire java installation is to provide some arguments to the call to java.

The message profiles for validating the messages exchanged in the context of the LAW (Laboratory Analytical Workflow) integration profiles have been updated to match the requirements expressed in the new version of the LAW supplement (1.4), published on March, 16th 2015.

You can access the GazelleHL7Validator through the EVSClient tool or directly called the validation SOAP webservice (documentation)

Following the Gazelle ObjectsChecker presentation at IHIC in Pragues in February 2015, we are posting here the JAR file for checking the conformance of a CDA® document to the HL7® CDA® R2 specification. 

The jar file can be downloaded here 

T he aim of this jar is to validate CDA® document with avoiding access to internet resources as gazelle ValueSet provider, or EVSClient resources ( There are two possible use cases of this jar : 

  1. using the jar as an executable (.sh for unix system / .bat for windows system)
  2. including the jar on a pre-existing java project, and using classes of the tool for validation.

1 - using the jar as a part of an executable (or command line interface CLI)

We have created this executable, so a user can specify the file to be validated and the CDA® validator to be used.

When checking the conformance of messages or content it is quite usefull to have the ability to view the content of the object that is checked.

We already add stylesheet to transform CDA and XDW documents into HTML, we have now added this feature to the ATNA Audit Message validation and the SAML Assertion validation section. 

In the file content section of the validation page, just click on the HTML tab in order to view an HTML representation of the checked object
