PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderExce
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.
