After my first experience in installing Neo4j graph database I decided to continue my experiments by writing a little Java demo program. The scope of my program just to learn how to connect to a Neo4j embedded graph, to generate ,connect and query some hundreds of nodes. Neo4j site and the downloaded manual provide plenty of documentation about interfacing with Java, and the other supported languages.
Setting up a Java project is quit simple: just matter of including all Neo4j libraries jars, available in the 'lib' folder, in the project class-path. To make easier future projects set-up I prepared, in Netbeans, a custom library configuration.
