Velocity with External Properties

     

This Example shows you how to use Velocity with External Properties. 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. Template  class object is used for controlling template methods and properties.

"runtime.log = velocity_example.log" is a external system property.  

 

 

ExternalProperties.java

import java.io.*;

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

public class ExternalProperties {

  public static void main(String[] args) throws Exception {

  Velocity.init(props);

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

  VelocityContext context = new VelocityContext();

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

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