Eureka! Clinical I2b2 Integration Webapp

Georgia Clinical and Translational Science Alliance (Georgia CTSA), Emory University, Atlanta, GA

What does it do?

It implements a proxy servlet and router for web clients to access the web services provided by eurekaclinical-i2b2-integration-service.

Version 2.0 development series

Latest release:

The 2.0 series will port the proxy over to the new eurekaclinical-i2b2-integration-service.

Version history

Version 1.0.1

The version 1 series implements the proxy and router for all service functionality, but it assumes the old version of the service (i2b2-eureka-service).

Build requirements

• Oracle Java JDK 8
• Maven 3.2.5 or greater

Runtime requirements

• Oracle Java JRE 8
• Tomcat 7
• Also running
  • The eurekaclinical-i2b2-integration-service war
  • The cas-server war

Proxied REST APIs

You can call all of eurekaclinical-i2b2-integration-service's REST APIs through the proxy. Replace /protected/api with /proxy-resource. The point of doing this is for web clients -- you can deploy the webapp on the same server as web client, and deploy the service on a separate server.

Building it

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.

Performing system tests

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-i2b2-integration-webapp/. Your username will be superuser.

Installation

Configuration

This webapp is configured using a properties file located at /etc/ec-i2b2-integration/application.properties. It supports the following properties:

• eurekaclinical.i2b2integrationwebapp.callbackserver = https://hostname:port
• eurekaclinical.i2b2integrationservice.url = https://hostname.of.service:port/eurekaclinical-i2b2-integration-service
• eurekaclinical.i2b2integrationwebapp.url = https://hostname:port/eurekaclinical-i2b2-integration-webapp
• cas.url=https://hostname.of.casserver:port/cas-server

A Tomcat restart is required to detect any changes to the configuration file.

WAR installation

1. Stop Tomcat.
2. Remove any old copies of the unpacked war from Tomcat's webapps directory.
3. Copy the warfile into the Tomcat webapps directory, renaming it to remove the version. For example, rename eurekaclinical-i2b2-integration-webapp-1.0.war to eurekaclinical-i2b2-integration-webapp.war.
4. Start Tomcat.
