Writing a simple Neo4j server - getting runtime error - neo4j

Question

I am a complete newbie to Neo4j. I am trying to write a simple Neo4j server that would listen on a port of my choice. The code I am using is exactly the same as in the file server.java at the following tutorial
http://hmkcode.com/first-time-neo4j/
The code compiles fine but when I try to run it I get an error (pasted below)
Any help would be appreciated. I am using jre7 and jdk1.8.0_11
For your convenience I have also cut and pasted the code below (exactly the same as in the above link)
import org.neo4j.graphdb.factory.GraphDatabaseFactory;
import org.neo4j.graphdb.factory.GraphDatabaseSetting;
import org.neo4j.kernel.GraphDatabaseAPI;
import org.neo4j.server.WrappingNeoServerBootstrapper;
import org.neo4j.server.configuration.Configurator;
import org.neo4j.server.configuration.ServerConfigurator;
import org.neo4j.shell.ShellSettings;
public class neoserver {
public static void main(String args[]){
{
GraphDatabaseAPI graphdb = (GraphDatabaseAPI) new GraphDatabaseFactory()
.newEmbeddedDatabaseBuilder( "db/graphDB" )
.setConfig( ShellSettings.remote_shell_enabled, GraphDatabaseSetting.TRUE )
.newGraphDatabase();
ServerConfigurator config;
config = new ServerConfigurator( graphdb );
// let the server endpoint be on a custom port
config.configuration().setProperty(Configurator.WEBSERVER_PORT_PROPERTY_KEY, 7575 );
WrappingNeoServerBootstrapper srv;
srv = new WrappingNeoServerBootstrapper( graphdb, config );
srv.start();
}
}
}
ERROR that I get

The tutorial you're referencing seems to use Eclipse and not a dedicated build system. Every serious project should not rely on and IDE for building, instead a tool like Maven or Gradle are a good choice.
Make sure you have all transitive dependencies of neo4j-server on your classpath. When using maven, add to your pom.xml with the dependencies section:
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<version>2.1.3</version>
</dependency>
In case of gradle, use inside dependencies:
compile 'org.neo4j.app:neo4j-server:2.1.3'
