[Deprecated] Gazelle Proxy - Installation & configuration

Warning: This documentation is out-dated, newest version of the documentation is available at https://gazelle.ihe.net/gazelle-documentation/Proxy/installation.html

Proxy is the part of the Gazelle testbed which is used to capture the messages exchanged between two systems under test. This tool is also bind to the EVSClient in order to validate the messages stored in the Proxy in a very simple way.

As for the other tools, the proxy is an open source project and its sources are available at https://scm.gforge.inria.fr/svn/gazelle/Maven/gazelle-proxy/. You can either download the latest tagged version or the current trunk.


Gazelle testbed tools are built using Maven 3, when you have download the sources, go to the gazelle-proxy folder and execute

mvn -P public clean package

You will get an EAR in the gazelle-proxy-ear/target folder.


You can download the latest gazelle-proxy.ear in nexus http://gazelle.ihe.net/nexus/index.html#nexus-search;quick~gazelle-proxy.ear

/!\ BE CAREFUL  /!\

We have ported the proxy to Jboss 7. The Jboss 5 version is maintained for bug fixes, but new features will only be added to the Jboss 7 version. If you are using the Jboss 5 version, use EAR 3.X.X, for Jboss 7 use version 4.0.0 or above.

To Summarize : 

  • Jboss 5 : from version 0.1 to 3.X.X
  • Jboss 7.2.0  (download link): from version 4.0.0 and above

/!\ BE CAREFUL  /!\


Then, follow the instructions below:

  1. In your database (postgresql 8.4 or higher) create a database named "gazelle-proxy", using UTF-8 encoding and owned by the user gazelle
    createdb -U gazelle -E UTF8 gazelle-proxy
  2. On your file system, create a directory /opt/proxy/DICOM
  3. Put the ear in the deploy folder of your Jboss AS
  4. Start Jboss AS
  5. Execute the sql script available in your workspace at gazelle-proxy-ear/src/main/sql/init.sql
    psql -U gazelle gazelle-proxy < init.sql
  6. Open your favorite browser (we recommand Chrome or Firefox) and go to http://yourServer:8080/proxy
  7. The proxy is now up and running, see the next section for information on the configuration.

This new instance of the proxy is running without the CAS feature, that means that anyone accessing the tool has the administrator privileges.

If you rather want to use a single-sign one authentication, configure the application in this way. Edit the preference application_works_without_cas to set it to false, 

Called tools

Check that dcmtk is installed on the machine. Actually, the proxy uses dcmdump to render the dicom files.


There is a set of properties that you can configure on the Configuration page, the table below describes the various properties defined and their default values.
