Need to download Jad and install
1, the download to the Jad Anti-compilation tool decompression, the resulting jad.exe placed in a directory of the system, such as C:/java/jre1.5.0_07/bin; (location can be placed casually, later configuration to use, recommended to put in the Java directory)
2, the download to the Jadclipse compressed package Net.sf.jadclipse_3.3.0.jar (corresponding to the version you just downloaded) placed in the Eclipse directory plugins (the directory is specifically placed plug-ins, you can also set up a folder to place the plug-in, But remember the path, you need to configure it later)
Startup configuration
When the installation is complete, Eclipse automatically sets the Jadclipse class file viewer to the default open mode for class files.
If there is no default, you can modify the "*.class" default associated editor in windows--> Perference-->general->editors->file associations in Eclipse as " Jadclipse Class File Viewer.
Once the settings are complete, double-click the *.class file and eclipse will automatically decompile.
For a class that has a source code, it does not forcibly decompile, that is, it will view the class file with the eclipse's own class files viewer and manually set the window->preferences->java-> Jadclipse, the Ignore existing source selected, will not control whether there is no source code, will be anti-compilation
