Exception:org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper cannot be cast to oracle.jdbc.OracleConnection

Hi All,

i am using jdev version 11.1.1.5.0

and deployed my Adf application on Apache Tomcat 6.0.

1. in my use case i have created simple adf application using adf business component. create a vo based on eo and drag-drop on jspx page.
2. i have created JNDI data source in Apache server using edit context.xml file and add following line-

<Resource name="jdbc/TestDB" auth="Container"

              type="javax.sql.DataSource" driverClassName="oracle.jdbc.OracleDriver"

              url="jdbc:oracle:thin:@localhost:1521:dst"

              username="jagrandb" password="jagrantest" maxActive="20" maxIdle="10"

              maxWait="-1"  accessToUnderlyingConnectionAllowed="true" />

3.using same data source in my adf applicatioin as -

  right click on AM --> Configuration-->edit-->select connection type jdbc datasource  -->java:/comp/env/jdbc/TestDB  

4. after that i have deployed my application on apace server but when i have running application i have got following error-

org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper cannot be cast to oracle.jdbc.OracleConnection

i have goggling and find  following solution-

oracle.jdbc.driver.OracleConnection delConn = (oracle.jdbc.driver.OracleConnection) ((org.apache.tomcat.dbcp.dbcp.DelegatingConnection)c_stmt.getConnection()).getDelegate();

but my problem is that i'm using Adf Business Component so where i set following type casting.

Is there any method on ADF BC which handle JNDI Data source setting or any other way to do this.

thanks in Advance

Manish
