PI 安装升级后：JNLP文件中的JAR资源签名证书不一致
PI Installation or upgrade ：JAR resources in JNLP file are not signed by same certificat
在PI升级或安装后容易出现的问题，当启动Enterprise Services Builder 或者 Integration Builder 时报JAR resources in JNLP file are not signed by same certificat，解决方法如下：
1. 登录http://host:5XX00/dir/start/index.jsp -> Administration -> Java Web Start Administration ->Restore archives / Restore Archives and Generate New Signature
2. 清除JAVA 客户端缓存
启动java控制面板:开始->运行->javaws –viewer / javaw , 常规->设置->删除文件
3. 检查component 版本一致性
参考 Note 1598282 - XI/PI:Jar Files are signed by different certificates in 2011
CORE-TOOLS, SAP_XI_ESR, SAP_XITOOL and SAP_XIGUI
多半是因为这个原因
4. 其它note
Note 1335523 - FAQ: Deployment PI Patches in Release 7.1 and higher
Note 1602945 - Not able to start Integration Builder after SPS upgrade
