Jess Web Application

This app uses the Jess rule engine to create automatic recommendations for users, based on what they already bought.

There are 2 main Jess files in the src/main/webapp folder:

• app.clp - contains all the business logic rules and the definition of the different product / recommendation templates
• facts.clp - use this file to load additional facts in your application.

Running the app

The app uses Gradle as a package manager and build engine. First, you need to setup the jess library, as it's an external JAR.

Installation steps:

1. In the libs folder, add the jess.jar file from ./deps/Jess71p2/lib/ (once extracted).
2. Run ./gradlew build
3. Run ./gradlew appRun to run it locally in an in-process Gretty servlet container.

In order to package everything and deploy it as a WAR to tomcat, for example, run:

./gradlew war

Then, take the file from build/libs/jess-webapp.war and put it in your webapp folder for the servlet engine.

Development

In order to change implementation details from the web application, everything can be found under src/main/webapp for the jsp and clp files.

I strongly suggest using IntelliJ for developing the code in this project. The idea plugin is already provided by gradle. To setup your local development files, run:

./gradlew idea
