public class HelloWorld
{
public static void main( String[] args )
{
/*
* first, get and initialize a Velocity
engine

try{
VelocityEngine ve = new VelocityEngine();
Properties p = new Properties();
p.setProperty("file.resource.loader.path",
"/root/workspace/Test/hello");
//Velocity.init( p );
ve.init(p);
/*

Template t =null;
t = ve.getTemplate( "HelloWorld.vm" );
/*

StringWriter writer = new StringWriter();
t.merge( context, writer );
/*
