【原】跟浏览器相关的几个java方案

 最近对iteye举办的问答大赛非常着迷，总想为更多的人答疑解惑。得到别人的点赞，荣誉感瞬间爆棚。这也折射出程序员这个职业的弊端。虽然问题大多都是初级水平，毕竟不懂才问的啊，闻到有先后，术业有专攻。那些大神们对这个很不屑，觉得拉低了他们的智商。这个我不很赞同，好了就这么多了把……

通过问答，我发现了一款很好的工具，记录下来，以后可能会有用武之地。

【htmlUnit】

htmlunit 是一款开源的java 页面分析工具，读取页面后，可以有效的使用htmlunit分析页面上的内容。项目可以模拟浏览器运行，被誉为java浏览器的开源实现。这个没有界面的浏览器，运行速度也是非常迅速的。可以作为小型的爬虫框架。

【MozSwing 】

MozSwing 独立运行，不依赖客户机器的浏览器版本。（目前来看最适合我们，内核是火狐的xulrunner1.9.1），官方好几年没有升级版本了。下载地址：http://sourceforge.net/projects/mozswing/）

【JWebBrowser】

JWebBrowser 调用客户本机浏览器，通常是IE。（下载： http://sourceforge.net/projects/djproject/files/DJ%20Native%20Swing/1.0.2%20preview/DJNativeSwing-SWT-1-0-2-20111030.zip/download）
