h1. Small Dijkstra example using "Neo4j":http://neo4j.org/

!http://github.com/neo4j-examples/java-dijkstra/raw/master/src/main/model/nodespace.png!

Requirements

To execute the project, Java 5+ is needed.

Download packages

There's download packages located here: "m2.neo4j.org/...java-dijkstra...":http://m2.neo4j.org/org/neo4j/examples/java-dijkstra/1.0.0-SNAPSHOT/ 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":http://wiki.neo4j.org/content/Java_Setup_HowTo 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.
