标记可以调用JavaBeans组件或者执行客户的请求，这大大降低了JSP开发的复杂度和维护量。JSP技术也允许你自定义taglib，其实换句话说，taglib可以看成是对JSP标记的一种扩展，正如xml是对html的一种扩展一样。taglib通常定义在tag标签库中，这种标签库存放着你自己定义的tag标签。简而言之，如果使用taglib，那么你可以设计自己的JSP标记！ 一般来说，自定义tag标签主要用于操作隐藏对象、处理html提交表单、访问数据库或其它企业级的服务，诸如邮件和目录操作等等。自定义tag标签的使用者一般都是那些对java编程语言非常精通，而且对数据访问和企业级服务访问都非常熟悉的程序员，对于HTML设计者来说，使得他可以不去关注那些较复杂的商业逻辑，而将精力放在网页设计上。同时，它也将库开发者和库使用者进行合理分工，自定义tag标签将那些重复工作进行封装，从而大大提高了生产力，而且可以使得tag库可用于不同的项目中，完美地体现了软件复用的思想。

1.5提供了“Varargs”机制。借助这一机制，可以定义能和多个实参相匹配的形参。从而，可以用一种更简单的方式，来传递个数可变的实参。本文介绍这一机制的使用方法，以及这一机制与数组、泛型、重载之间的相互作用时的若干问题。<img src ="http://blog.csdn.net/leek2000/aggbug/348582.aspx" width = "1" height = "1"
