import java.util.Map;

import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateException;

public class StringIndexTest {

  /**
   @param args
   @throws IOException 
   @throws TemplateException 
   */
  public static void main(String[] argsthrows IOException, TemplateException  {

    //Get template from classpath
    Configuration cfg = new Configuration();
    cfg.setClassForTemplateLoading(StringIndexTest.class, "/");
    Template template = cfg.getTemplate("strindex.ftl");
    
    //Prepare data model
    Map<String, Object> dataModel = new HashMap<String, Object>();
    
    //Merge template and data
    StringWriter output = new StringWriter();
    template.process(dataModel, output);
    
    System.out.println(output.toString());
  }
}
