本文介绍了如何使用ProGuard 4.2工具处理SSH项目的源码。详细步骤包括：设置输入输出路径、选择库文件、设置缩小、混淆和保留属性等选项，以及处理后的效果和可能出现的问题。

假设Java安装在C:\Program Files\Java，Tomcat安装在：D:\apache-tomcat-6.0.35，要处理的SSH项目部署在D:\apache-tomcat-6.0.35\webapps\MySSHWeb。首先解压ProGuard 4.2，得到其lib目录下的proguardgui.jar、proguard.jar和retrace.jar三个文件；在同一目录下建立脚本文件start.bat，文件内容为：java -Xms512m -Xmx512m -jar proguardgui.jar。运行start.bat打开ProGuard，然后开始设置：

1：在Input/Output页进行设置：
   Add input...，输入D:\apache-tomcat-6.0.35\webapps\MySSHWeb\WEB-INF\classes
   Add output...，输入D:\apache-tomcat-6.0.35\webapps\MySSHWeb\WEB-INF\classes_ok
   Add...，输入D:\apache-tomcat-6.0.35\lib
   Add...，输入D:\apache-tomcat-6.0.35\webapps\MySSHWeb\WEB-INF\lib

2: 在Shrinking页进行设置：
   取消Applications，选中Library
   Add...，Comments为Keep Hibernate PO，Extends/implements class为java.io.Serializable
   Add field...，点OK
   Add method...，点OK
   最后点OK

3: 在Obfuscation页进行设置：
选中Keep attributes

4: 在Information页进行设置：
选中Target，下拉选择1.5

5: 在Process页，点击Process!开始处理

最后可以得到处理后的classes，覆盖到D:\apache-tomcat-6.0.35\webapps\MySSHWeb\WEB-INF\classes下即可。偶尔会出现个别文件有错，可以直接将对应的原文件覆盖过来。最终处理的效果不是很好，有待进一步研究。最终的配置文件如下所示：

-injars 'D:\apache-tomcat-6.0.35\webapps\MySSHWeb\WEB-INF\classes_bak'
-outjars classes_bak_yes

-libraryjars 'C:\Program Files\Java\jre6\lib\rt.jar'

}
