A ORA-01005 error is reported when you access the ADF application deployed in Weblogic

Today, when deploying Oracle Summit Demo to a standalone Weblogic, ORA-01005 exceptions are reported, and running in Integrated Weblogic is always normal.

The main exception Log is as follows:

I don't understand why the password is blank. Fortunately, Gu Ge has the following solutions:
 
Add the following parameter to JAVA_PROPERTIES in FMW_HOME/user_projects/domains/yourdomain/bin/setDomainEnv. sh:

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

Result:

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

Restart Weblogic and then access the application. Everything works...
