PI 安裝升級后：JNLP文件中的JAR資源簽名證書不一致
PI Installation or upgrade ：JAR resources in JNLP file are not signed by same certificat
在PI升級或安裝后容易出現的問題，當啟動Enterprise Services Builder 或者 Integration Builder 時報JAR resources in JNLP file are not signed by same certificat，解決方法如下：
1. 登錄http://host:5XX00/dir/start/index.jsp -> Administration -> Java Web Start Administration ->Restore archives / Restore Archives and Generate New Signature
2. 清除JAVA 客戶端緩存
啟動java控制面板:開始->運行->javaws –viewer / javaw , 常規->設置->刪除文件
3. 檢查component 版本一致性
參考 Note 1598282 - XI/PI:Jar Files are signed by different certificates in 2011
CORE-TOOLS, SAP_XI_ESR, SAP_XITOOL and SAP_XIGUI
多半是因為這個原因
4. 其它note
