简易的java发邮件客户端

主要是想熟悉一下jigloo插件的使用，所以做了一个发邮件的小程序，其实调用的都是人家的东西，我们自己只做了最简单的傻瓜操作，每思及此，感觉要学的东西还很多。

 

本人很懒，搞swing那套东西很不给力，所以就用jigloo插件帮我布个局，代码跟图形界面的编辑其实是完全独立的，有了代码可以直接运行无需jigloo插件。

另外需要下载两个jar文件：mail.jar和activation.jar，这是java发邮件所必须的类库

下载不到可以去http://download.csdn.net/source/2676485我上传的

（做这么龊下载还要分？好吧，我发邮件你总行了把）

 

直接上码，大家一看就都明白了，Resources类里面的图，大家随便放几个图进去吧
