访问Weblogic中部署的ADF应用时，报ORA-01005错误

今天在将Oracle Summit Demo 部署到独立的Weblogic中时，一直报ORA-01005异常；在Integrated Weblogic中运行则是一直正常。

今天在将oracle summit demo 部署到独立的weblogic中时，，一直报ora-01005异常；在integrated weblogic中运行则是一直正常。

主要异常Log如下：

不理解为何密码会是空，还好有谷哥，解决方案：
 
在FMW_HOME/user_projects/domains/yourdomain/bin/setDomainEnv.sh中的JAVA_PROPERTIES中加如下参数：

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

结果为：

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

然后重启Weblogic，再访问应用，一切正常。。。
