smack-config.xml这个文件无法加载是什么原因
我现在是维护一个网站，工程是从服务器上面下载的，shujuku也是下载的原版的，但是在服务器上面工程是可以注册的，到了本地的机器上面出现不能注册的情况：具体报错是：
pstmt=com.mysql.jdbc.ServerPreparedStatement[2] - INSERT INTO people(phone,sex,age,update_date,postcode,address,email,grad_date,name,create_date,id,pwd) VALUES(null,null,null,null,null,null,null,null,null,null,null,null)
pstmt2=com.mysql.jdbc.ServerPreparedStatement[2] - INSERT INTO people(phone,sex,age,update_date,postcode,address,email,grad_date,name,create_date,id,pwd) VALUES('','',0,'2008-09-17','','','lhp636@163.com','','','2008-09-17','lhp636@163.com','636636')
noOfRows1=0
noOfRows2=1

就是错误！启动级中指定的smack - config.xml中无法加载：
这可能是什么原因造成的，是缺包了吗？
smack-config.xml这个文件我的包里没有见过，好像没有这个文件（因为工程不是我写的）

------解决方案--------------------
可能里面用到了XMPP
到这里下载个smack包吧
