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.

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 (http://gazelle.ihe.net/EVSClient). 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

Please let me know if you have questions about this subject.

Gazelle Test Bed was enriched with a new validator. This validation tool performs validation of messages as specified in the Document Metadata Subscription (DSUB) profile.

The validator is already reachable from the EVSClient application as shown on the following screen capture :

Bug report, suggestions or comments are as always welcome, please use JIRA to report them.

As planned in our information page : http://gazelle.ihe.net/content/ihe-europe-2013-connectathon we have 2 webinars next weeks.
  • The 2 webinars are (almost) identical. We repeat it to allow participants in Asia and in North America to attend at a reasonable time.
  • The purpose of the webinars is to inform participants to the connectathon about the process
    • how to prepare them selves to the connectathon
