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.
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:
- In the
libsfolder, add thejess.jarfile from./deps/Jess71p2/lib/(once extracted). - Run
./gradlew build - Run
./gradlew appRunto 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.
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
This hasn't been tested on Windows, please let me know if there's any issue with it.
