Hi,

I am trying to start neo4j server using , 

org.neo4j.server.Bootstrapper

String[] args = new String[1];
args[0] = "start";

Bootstrapper.main(args);


When i run the code, I get the following exception :

Why do you want to do it?

Did you check the bin/neo4j startup script for the required parameters?

I usually just use bootstrapper.start()
