今天一个sso项目把我折腾了半天，最终还是搞定了成功部署到linux环境上了.

遇到的错误如下：

解决方案：

原因是因为JDK的目录下没有导入证书. C:\Program Files\jdk1.7.0_64\jre\lib\security

直接通过dos的命令

导入到JDK安装目录证书:

keytool -import -keystore C:/"Program Files"/Java/jdk1.6.0_32/jre/lib/security/cacerts -file C:/common/keys/keycard.crt -alias mycacerts

或者

是把证书手动复制到此目录即可.
