你可以用 Ant 来执行 Java 代码。在下面的例子中，给出的 java 类文件需要一个参数（管理员的邮箱地址），执行后将发送一封邮件。

public class NotifyAdministrator
{
   public static void main(String[] args)
   {
      String email = args[0];
      notifyAdministratorviaEmail(email);
      System.out.println("Administrator "+email+" has been notified");
   }
   public static void notifyAdministratorviaEmail(String email
   { 
       //......
   }
}

<?xml version="1.0"?>
<project name="sample" basedir="." default="notify">
   <target name="notify">
      <java fork="true" failonerror="yes" classname="NotifyAdministrator">
         <arg line="admin@test.com"/>
      </java>
   </target>
</project>
