訪問Weblogic中部署的ADF應用時，報ORA-01005錯誤

今天在將Oracle Summit Demo 部署到獨立的Weblogic中時，一直報ORA-01005異常；在Integrated Weblogic中運行則是一直正常。

主要異常Log如下：

不理解為何密碼會是空，還好有穀哥，解決方案：
 
在FMW_HOME/user_projects/domains/yourdomain/bin/setDomainEnv.sh中的JAVA_PROPERTIES中加如下參數：

-Djps.app.credential.overwrite.allowed=true

結果為：

JAVA_PROPERTIES="-Dplatform.home=${WL_HOME} -Dwls.home=${WLS_HOME} -Dweblogic.home=${WLS_HOME} -Djps.app.credential.overwrite.allowed=true "

然後重啟Weblogic，再訪問應用，一切正常。。。
