A Java EE 8 web application for visualizing schedules and aiding work coordination at Jefferson Lab.
The accelerator task list calendar provides a visualization of schedules to aid with work coordination of ATLis tasks. The calender is most often used during Scheduled Accelerator Down (SAD) periods so is often referred to as the SAD Calendar.
- Grab project
git clone https://github.com/JeffersonLab/calendar
cd calendar
- Launch Compose
docker compose up
- Navigate to page
http://localhost:8080/calendar
Note: Login with demo username "tbrown" and password "password".
This application requires a Java 11+ JVM and standard library to run, plus a Java EE 8+ application server (developed with Wildfly).
- Install service dependencies
- Download Wildfly 26.1.3
- Configure Wildfly and start it
- Download calendar.war and deploy it to Wildfly
- Navigate your web browser to localhost:8080/calendar
Wildfly must be pre-configured before the first deployment of the app. The wildfly bash scripts can be used to accomplish this. See the Dockerfile for an example.
Uses a subset of the Smoothness Environment Variables including:
- BACKEND_SERVER_URL
- FRONTEND_SERVER_URL
- PUPPET_SHOW_SERVER_URL
The application requires an Oracle 18+ database with the following schema installed. The application server hosting the app must also be configured with a JNDI datasource.
This project is built with Java 17 (compiled to Java 11 bytecode), and uses the Gradle 7 build tool to automatically download dependencies and build the project from source:
git clone https://github.com/JeffersonLab/calendar
cd calendar
gradlew build
Note: If you do not already have Gradle installed, it will be installed automatically by the wrapper script included in the source
Note for JLab On-Site Users: Jefferson Lab has an intercepting proxy
In order to iterate rapidly when making changes it's often useful to run the app directly on the local workstation, perhaps leveraging an IDE. In this scenario run the service dependencies with:
docker compose -f deps.yml up
Note: The local install of Wildfly should be configured to proxy connections to services via localhost and therefore the environment variables should contain:
KEYCLOAK_BACKEND_SERVER_URL=http://localhost:8081
FRONTEND_SERVER_URL=https://localhost:8443
Further, the local DataSource must also leverage localhost port forwarding so the standalone.xml connection-url field should be: jdbc:oracle:thin:@//localhost:1521/xepdb1.
The server and app setup scripts can be used to setup a local instance of Wildfly.
- Bump the date and version number in build.gradle and commit and push to GitHub (using Semantic Versioning).
- Create a new release on the GitHub Releases page corresponding to the same version in the build.gradle. The release should enumerate changes and link issues. A war artifact can be attached to the release to facilitate easy install by users.
- Publish to DockerHub GitHub Action should run automatically.
- Bump and commit quick start image version
At JLab this app is found at ace.jlab.org/calendar and internally at acctest.acc.jlab.org/calendar. However, those servers are proxies for wildfly6.acc.jlab.org and wildflytest6.acc.jlab.org respectively. A deploy script is provided to automate wget and deploy. Example:
/root/setup/deploy.sh calendar v1.2.3
