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：C:\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）：

4.重启MyEclipse,配置 jadclipse

 

在Eclipse 的Windows—> Perferences—>General->Editors->File Associations 中修改“*.class”默认关联的编辑器为“JadClipse Class File Viewer”。如果没有*.class，则点击“add"增加一个。

  

 

 

 

 

 

 

如果遇到如下错误，解决方式：

 

eclipse中添加jad插件

 

 

1. 下载jad: http://www.softpedia.com/progDownload/JAD-Download-85911.html

下载后, 将解压后的jad.exe放到某个目录下, 如: D:java/jad.exe(后面会用到这个路径)

2. 下载jadClipse插件: http://sourceforge.net/projects/jadclipse/files/

将解压后的jar文件放到Eclipse的plugins子目录下

3. 重启eclipse

4. 配置JadClipse:

打开Windows ->Preferences -> Java -> JadClipse选项, 在path to decomplier: 文本框中写入D:\java\jad.exe(先前下载jad.exe的路径)

然后,点击确定, 重启eclipse即可完成jad插件的添加

 

另外, 出现如下问题, 多半是JadClipse没有配置好, 按上述步骤配置即可解决问题.
