MyEclipse XX安装jad反编译插件

1.下载反编译工具jad，下载地址：http://varaneckas.com/jad/

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 FilesJavajdk1.6.0_20in 

2.下载eclipse反编译插件net.sf.jadclipse_3.3.0.jar，下载地址：http://prdownloads.sourceforge.net/jadclipse/net.sf.jadclipse_3.3.0.jar?download

3.将net.sf.jadclipse_3.3.0.jar 放入MyEclipse安装目录下，

 如 ：安装目录Genuitecdropins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）：

    }     
    
    public String getString(Object object)

    public static void main(String[] args)

        String plugin = "E:\Program files\myeclipse\eclipse\plugins";  
        new CreatePluginsConfig().print(plugin);     
    }     
}   

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。到这里就可以打开.class文件了。
