Small Dijkstra example using Neo4j

Requirements

To execute the project, Java 5+ is needed.

Download packages

There’s download packages located here:
m2.neo4j.org/…java-dijkstra…
Look for files ending in .zip or .tar.gz

Contents of the download package

bin/	start script for the application in Unix and Windows format
docs/	javadoc of all Neo4j component dependencies of the project
lib/	all dependency jars of the project
lib/report	dependency report including license information
src/	source code of the project

Run from download package

Simply start the corresponding script in the bin/ directory. For example:
$ ./bin/dijkstra

Run from source

Using JDK:
Use the download package and add the lib/ directory
to the project classpath (“build path” in Eclipse).
In this case, only JDK 1.6 is required to run the code
from source.

Using JDK + Maven:
Checkout or download the source code from GitHub and use the Maven2
setup originally used for the project. This option requires
JDK 1.5 and Maven2 to be installed, see: Java Setup
With Maven2 installed, simply issue the following command
at the command prompt:
$ mvn clean compile exec:java -Dexec.mainClass="org.neo4j.examples.dijkstra.DijkstraExample"
This command will download all dependencies which are needed on the first run.

Sample output
