小弟用eclipse6.6写jsp程序时，相关包已经引入，用Set和Iterator定义对象老报错，内容如下： Multiple annotations found at this line:
-The type Set/Iterator is not generic;it cannot be parameterized with argument <artile>
-Syntax error,parameterized types are only available is source level is 5.0
(artile是我定义的一public类） 请问是eclipse版本的问题吗，6.6应该和5.0兼容的啊，如果不是版本问题那该怎么解决,请指教啊,多谢!(原来用6.0没有此问题)
