SWING内嵌浏览器、播放flash等应用

前两天有一个挺奇怪的应用需求：在SWING程序中内嵌浏览器，并与页面进行内容的交互，同时，浏览器打开的是已有系统，不提供任何接口。

在网上搜索了一下思路，发现了一个开源项目--DJproject，这个开源项目，在SWING中内嵌了浏览器，可以在浏览器中执行简单的JavaScript代码，同时还有播放Flash等其他功能。

内嵌浏览器源代码

感觉这个项目做得还是挺新颖的，但是，当内嵌浏览器，并与页面进行交互时，做得还是不好。比如API中执行JavaScript代码为 webBrowser.executeJavascript（），此方法还是只能执行简单的JS语句，稍微复杂一点的JS函数，是执行不了的。同时，获取和设置页面内容的代码为 webBrowser.getHtmlContent(),webBrowser.setHtmlContent(),这两个方法在实际使用时，比如打开sina主页，调用getHtmlContent()方法，取到的内容为空，达不到在浏览器右键查看页面源文件的效果。所以最终这个项目还是没能帮助我实现需求。

这两个怎么导入啊？没有对应的包

怎么只有demo的jar包啊，没有DJNativeSwing的jar包，博主请把DJNativeSwing的jar包也放出来吧
