Error -ora-28267: invalid namespace -ADF With Jdeveloper

There was a requirement to validated the Local Entity Attribute value against the Remote Database. For this we set-up the DB link. Local DB is 11g and remote is 10g.
During the query validation in JDEV we go the issue."ora-28267: invalid namespace" .

To Fix this in JDV.

"C:\Oracle\Middleware11.1.1.7.0\oracle_common\modules\oracle.jdbc_11.1.1\"
