ojdbc6.jar dependency error when using weblogic smartupgrade.

Hello,

while upgrading a old shared library jar file , JDeveloper Smartupgrade shows the following required public dependency:

 

'xxxxx.jar contains the following Oracle public dependencies. xxxxxx.class on ( oracle.jdbc.pool.OracleDataSource (ojdbc6.jar))'

 

we have a ojdbc6.jar in the C:\Oracle\middleware\wlsserver_10.3\server\lib

 

and in jdeveloper menu > tools > manage libraries> in extensions , i can see 'Oracle JDBC' , class path is

C:\Oracle\Middleware\jdeveloper\ide\macros\..\..\..\wlsserver_10.3\server\lib

we also have created datasources under application > resources> connections, ( database connection name is same as data sources used in 'xxxxx.jar being upgraded. )

the integrated weblogic server is started as well.
