JSON-taglib是一套JSP标签库用于在JSP代码中输出JSON格式的数据。JSON-taglib利用json:array, json:object和json:property来实现数据格式的转换。
下面是具体用法：
Just drop the json-taglib.jar file into the WEB-INF/lib directory of your web-application.
Here's a quick example of how the taglib could be used with an AJAX e-commerce shopping cart. Check out the examples or the tutorial for full details of how to use the taglib.
