JarCastingEureka! Clinical Registry Service
Atlanta Clinical and Translational Science Institute (ACTSI), Emory University, Atlanta, GA
The registry service provides a list of deployed Eureka! Clinical components. Its initial purpose is for resource discovery such as populating menus and other lists of available components.
Version history
Latest release:
Version 1.1
The properties in the application.properties were named in a non-standard way in version 1.0, starting with eurekaclinical.registry.service rather than eurekaclinical.registryservice. Version 1.1 added standard property names. It responds to either, and it prioritizes the original non-standard names if both are present. The non-standard property names are deprecated and will be removed in a future release.
We also updated the README.md.

The project uses the maven build tool. Typically, you build it by invoking mvn clean install at the command line. For simple file changes, not additions or deletions, you can usually use mvn install. See https://github.com/eurekaclinical/dev-wiki/wiki/Building-Eureka!-Clinical-projects for more details.
You can run this project in an embedded tomcat by executing mvn process-resources cargo:run -Ptomcat after you have built it. It will be accessible in your web browser at https://localhost:8443/eurekaclinical-registry-service/. Your username will be superuser.
A Liquibase changelog is provided in src/main/resources/dbmigration/ for creating the schema and objects. Liquibase 3.3 or greater is required.
Perform the following steps:
- Create a schema in your database and a user account for accessing that schema.
- Get a JDBC driver for your database and put it the liquibase lib directory.
- Run the following:
./liquibase \
--driver=JDBC_DRIVER_CLASS_NAME \
--classpath=/path/to/jdbcdriver.jar:/path/to/eurekaclinical-registry-service.war \
--changeLogFile=dbmigration/changelog-master.xml \
--url="JDBC_CONNECTION_URL" \
--username=DB_USER \
--password=DB_PASS \
update
- Add the following Resource tag to Tomcat's
context.xmlfile:
<Context>
...
<Resource name="jdbc/EurekaClinicalServiceRegistryService" auth="Container"
type="javax.sql.DataSource"
driverClassName="JDBC_DRIVER_CLASS_NAME"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
url="JDBC_CONNECTION_URL"
username="DB_USER" password="DB_PASS"
initialSize="3" maxActive="20" maxIdle="3" minIdle="1"
maxWait="-1" validationQuery="SELECT 1" testOnBorrow="true"/>
...
</Context>
The validation query above is suitable for PostgreSQL. For Oracle and H2, use SELECT 1 FROM DUAL.
This service is configured using a properties file located at /etc/ec-registry/application.properties. It supports the following properties:
eurekaclinical.domain.url: https://hostname:porteurekaclinical.registryservice.callbackserver: https://hostname:porteurekaclinical.registryservice.url: https://hostname:port/eurekaclinical-registry-servicecas.url: https://hostname.of.casserver:port/cas-server
It also supports the following deprecated properties:
eurekaclinical.registry.service.callbackserver: replaced byeurekaclinical.registryservice.callbackservereurekaclinical.registry.service.url: replaced byeurekaclinical.registryservice.url
These deprecated properties will be removed in a future release.
A Tomcat restart is required to detect any changes to the configuration file.
- Stop Tomcat.
- Remove any old copies of the unpacked war from Tomcat's webapps directory.
- Copy the warfile into the tomcat webapps directory, renaming it to remove the version. For example, rename
eurekaclinical-registry-service-1.0-SNAPSHOT.wartoeurekaclinical-registry-service.war. - Start Tomcat.
