Show content of .vm file as output using Velocity

Show content of .vm file as output using Velocity

     

This Example shows you how to display content of .vm file using velocity and also shows how to use Iterator in velocity  template. The method used in this example are described below:-  
1:- Initialize velocity run time engine through method  init().
2:- Create object of VelocityContext Class.
3:- Create Template class object, Template  class object is used for controlling template methods and properties.

template.merge(context, writer): Merge method of the Template class is used here for merging  the VelocityContext class object to produce the output.

There is a message "Hi, this is Komal Choudhary..." in StringOutput.vm file, that message will be show as output.

 

 

StringOutput.java

import java.io.*

import org.apache.velocity.*;
import org.apache.velocity.app.Velocity;

public class StringOutput {

  public static void main(String[] args) throws Exception {
  Velocity.init();

  Template template = Velocity.getTemplate("./src/StringOutput.vm");

  VelocityContext context = new VelocityContext();

  Writer writer = new StringWriter();
  template.merge(context, writer);

  System.out.println(writer.toString());
  }
}

StringOutput.vm
Hi, this is Komal Choudhary...

Output:
  
Hi, this is Komal Choudhary...
