本文为合成篇，但亲自测试无误的。
------------------------
1.下载反编译工具jad（下面提供下载）
将下载下来的jadstar158.zip解压缩，将jad.exe文件放入jdk安装目录下
如：D:\Program Files\Java\jdk1.6.0_20\bin?
?
2.下载eclipse反编译插件net.sf.jadclipse_3.3.0.jar（下面提供下载）
?
?
3.将net.sf.jadclipse_3.3.0.jar?放入MyEclipse安装目录下，
?如?：安装目录\Genuitec\dropins下?没有dropins，新建之，然后在dropins中新建features文件夹和plugins文件夹，将net.sf.jadclipse_3.3.0.jar拷贝到plugins中，然后新建java工程，运行以下代码（替换其中最后的代码，你电脑反编译插件所在的实际位置）：
