public static void main(String[] args) throws Exception {
Velocity.init();
Template t = Velocity.getTemplate("./src/VMDemo.vm");

VelocityContext ctx = new VelocityContext();

Writer writer = new StringWriter();
t.merge(ctx, writer);

System.out.println(writer);

VM file

#if ($City == "Hyderabad")
  Hi $first_Name welcome to Hyderabad.
#elseif ($City == "Berling")
  Hi $First_Name welcome to Berlin
#elseif ($City == "Mumbai")
  Hi $First_Name welcome to Mumbai
#else
 Please contact Us
#end
enter code here
the output should be like this..
Hi Rakesh welcome to Hyderabad.

Someone please suggest me how to load data and use in velocity. If Person belongs to some city then the name should be taken dynamically from a file. Please Someone help me out with this.. just help me including my file in velocity.

  • I need to understand your whole requirement . You mean to say 10k user you want to send msg? By reading the text file? – soorapadman Sep 20 '18 at 09:47
  • @manfromnowhere i am getting an exception like this SEVERE: ResourceManager : unable to find resource './src/apachefilepath.vm' in any resource loader. Exception in thread "main" org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource './src/apachefilepath.vm'.. – farhana fatima Sep 20 '18 at 09:52

  • Along with that You have to add this code snippet also to generate the output `VelocityContext ctx = new VelocityContext(); ctx.put("City", "Hyderabad");/ / Hyderabad should be dynamic ctx.put("first_name", "Rakesh");// This is also` – soorapadman Sep 20 '18 at 09:58

  • Did you put your `text file` under velocity folder ? – soorapadman Sep 20 '18 at 10:48
  • I think you can't use it like `#include("D:\\temp\\data.txt")` instead you can put under velocity folder and try `#include("data.txt")` – soorapadman Sep 20 '18 at 10:50
