Aristotle

Aristotle is a JSR 370 JAX-RS webservice of CRUD operations against a graph database. It supports Neo4J now.

Start Locally in Jetty

Navigate to a dedicated directory; make sure port 8080 is not occupied and the following environment variables are set:

export NEO4J_URI=
export NEO4J_USERNAME=
export NEO4J_PASSWORD=
export NEO4J_DATABASE=

Then start webservice with:

./jetty-start.sh

Press Ctr-C to stop the webservice and delete generated directories if needed when done.

Test

mvn clean verify

Deployment

At this moment deployment is manual and pretty much follows jetty-start.sh
