Sources & binaries

To get the name of the latest release, visit the Gazelle HL7 Validator project in JIRA and consult the “Change log” section.

A maven artifact is published in our Nexus repository each time we release the application. You can use it, but be aware that the link to the database is hardly expressed within the artifact so you will have to use the same database name, hosted in the server running Jboss, and with the same owner (and password).

To get the artifact on Nexus browse: https://gazelle.ihe.net/nexus/index.html#nexus-search;gavGazelleHL7v2Validator-ear~ and download the latest version.

If you rather want to build the project by yourself, you must checkout the latest tag and package it. You may want to create a new profile to customize your build.

  1. Checkout the latest tag available on Inria’s forge: svn co https://scm.gforge.inria.fr/svn/gazelle/Maven/GazelleHL7v2Validator/tags/GazelleHL7v2Validator-$versionName

  2. [Optional] Edit the pom.xml file and create a new profile

  3. Package the application: mvn \[-P profile\] clean package

  4. The EAR is available at GazelleHL7v2Validator/GazelleHL7v2Validator-ear/target/GazelleHL7v2Validator.ear

Step by step installation

First, please consider reading the General installation manual for Jboss 7.2.0 AS.

Database configuration

If you use the artifact available on Nexus or if you have not change this parameter in the pom.xml file, create a database named gazelle-hl7-validator, owned by the user gazelle.

$ createdb -U gazelle -E UTF8 gazelle-hl7-validator

Deploy the application

  • Copy EAR to the deploy folder of JBoss 7.2.0 AS(do not forget to change its name to GazelleHL7v2Validator.ear)
  • Start Jboss ⇒ sudo service jboss start
  • Wait until the application has been completly deployed and configure the database running the SQL script for set-up.

Initialize the application

You first need to initialize the database with some data available in a SQL script. If you have checked out the project, the script is available in GazelleHL7v2Validator-ear/src/main/sql/import.sql.

IMPORTANT NOTICE: Before to apply this script into your database, open it and replace the ‘to be defined.’ values to be inserted in the oid_generator table by the root OIDs defined for your instance of the tool. Be carefull and keep the final dot.

Otherwise, download it from Inria’s forge (See Sources section)

Before executing the script, open the file and checked the various preferences to be inserted in the app_configuration table, especially the cas_url, application_url and other preferences relative to the user authentication (see Application configuration section). Context path for deployment is /GazelleHL7Validator.

Finally, execute the script: 

$ psql -U gazelle gazelle-hl7-validator < import.sql

To take those parameters into account, you need to restart either the whole Jboss sudo service jboss7 restart, either only the application ($ touch GazelleHL7v2Validator.ear in the deploy folder of Jboss)

Application configuration

Use the Administration menu, you will find a sub-menu entitled “Configure application preferences”. The following preferences must be updated according to the configuration of your system. The table below summarizes the variables used by the Gazelle HL7 Validator tool.

Variable Description Default value
application_issue_tracker_url The URL of the bug tracking system where to post issues https://gazelle.ihe.net/jira/browse/HLVAL
application_url The URL used by any user to access the tool. The application needs it to build permanent links inside the tool http://publicUrlOfJboss/GazelleHL7Validator
cas_url If you intent to use a CAS, put its URL here https://gazelle.ihe.net/cas
force_stylesheet HL7MessageProfiles and HL7 resources are XML files displayed with a stylesheet declared in the file and referenced on gazelle.ihe.net. To avoid cross-site references, most browsers do not follow those links and as a consequence do not display the XML file correctly. This property tells the tool to change the link to the stylesheet before sending the file to the client true
gmm_hl7messageprofile_wsdl Access Hl7MessageProfile webservice exposed by GMM (or TM configured to work also as GMM) https://gazelle.ihe.net/gazelle-gmm-gazelle-tm-ejb/Hl7MessageProfile?wsdl

resource_xsl_url used if force_stylesheet = true link to the stylesheet (FDQN must be the same as for the application)

Home page

The first time you access the application, you may notice that the home page of the tool is not configured. To set a title and a welcome message, log into the application with admin rights.

Note that you will have to set up this page for all the languages supported by the application.

Upload of the documentation of the model-based validation service (for HL7v3 messages)

The administrator is able to configure the documentation of XDS/DSUB constraints and rules

First the user shall be logged in as an administrator.

Then, go to administration -> Constraints Management -> Constraints-admin

The user shall then upload the XML file generated from the model of constraints into the tool by using the add button from the previous page.

After the upload is ended, click on the button “Delete and Generate”. This button will delete all the constraints related to packages that are mentioned into the uploaded XML file. If there are some constraints related to other packages, they won’t be deleted. The information into the XML document is inserted in the database of the tool.
