JAVA+ Proxool+ SQLserver 2008 “signer information does not match signer information of other classes in the same package”

1. Proxool+SQLserver2008(sqljdbc4.jar)集成问题
最近在项目中遇到个问题:我用的是Proxool连接池,连接SQLserver2008数据库,控制台报错:签名信息和同一包里面的另外一个类得签名信息不匹配

Caused by: java.lang.SecurityException: class "com.microsoft.sqlserver.jdbc.ISQLServerStatement$$FastClassByProxool$$3407f37e"'s signer information does not match signer information of other classes in the same package

解决办法:用压缩软件打开sqljdbc4.jar 删除META-INFO目录下的检验文件MANIFEST.MF MSFTSIGN.RSA,MSFTSIG.SF即可
