import java.io.StringWriter;
import org.apache.velocity.app.VelocityEngine;
import org.apache.velocity.Template;
import org.apache.velocity.VelocityContext;
public class HelloWorld
{
    public static void main( String[] args )
        throws Exception
    {
        /* initialize an engine  */
        VelocityEngine ve = new VelocityEngine();
        ve.init();
  
        /*  get the Template  */
        Template t = ve.getTemplate( "sayHello.vm" );
       
  /*  create a contex */
        VelocityContext context = new VelocityContext();
        context.put("name", "John");
  
        StringWriter writer = new StringWriter();
       
  t.merge( context, writer );
  
        System.out.println( writer.toString() );    
    }
}
