J2EE Application is accessing Oracle Database Server  via a connection obtained from a proxy data source.
From this application, the  SQL query  select sys_context('userenv','proxy_user') from dual  returns NULL value.
However, the expected value is 'proxy_user' as the proxy data source/connection pool is configured with the "proxy_user" user.
