求助从class反编译文件，一字未改再编译时提示错误有100多处，请教？
环境参数已设置正常,我完全是按附件教程上讲的步步操作，到最后一步不行的。// Decompiled by Jad v1.5.8e2. Copyright 2001 Pavel Kouznetsov.

----------------解决方案--------------------------------------------------------
很显然，jar被加密过了，一看到那种III啊AAAA啊，肯定是加密过的，难以反编译回来
----------------解决方案--------------------------------------------------------
一般商业的东西都通过代码混淆过的，防止他人反编译窃取代码
