ADF testing Error ORA-01005.

Once my development is over and ready to my ADF page. I got an error as shown below.

oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection.
at oracle.jbo.server.ConnectionPool.createConnection(ConnectionPool.java:253)
at oracle.jbo.server.ConnectionPool.instantiateResource(ConnectionPool.java:168)
at oracle.jbo.pool.ResourcePool.createResource(ResourcePool.java:546)
at oracle.jbo.pool.ResourcePool.useResource(ResourcePool.java:327)
at oracle.jbo.server.ConnectionPool.getConnectionInternal(ConnectionPool.java:104)
Truncated. see log file for complete stacktrace
java.sql.SQLException: ORA-01005: null password given; logon denied

my problem was solved by adding below command to JAVA_PROPERTIES of (E:\Oracle\Middleware)Fussion_Middleware_Home\user_projects\domains\second_domain\bin\setDomainEnv.cmd(.sh for unix)

Before: 

set JAVA_PROPERTIES=-Dplatform.home=%WL_HOME% -Dwls.home=%WLS_HOME% -Dweblogic.home=%WLS_HOME%

After: 

set JAVA_PROPERTIES=-Dplatform.home=%WL_HOME% -Dwls.home=%WLS_HOME% -Dweblogic.home=%WLS_HOME% -Djps.app.credential.overwrite.allowed=true
