Am using Websphere 18 Liberty Version. When am trying to unwrap java.sql.connection to oracle.jdbc.OracleConnection I get the
`DSRA9122E: com.ibm.ws.rsadapter.jdbc.WSJdbcConnection@d3t7e556 does not wrap any objects of type oracle.jdbc.OracleConnection
In sever.xml file am using ojdbc7.jar for datasource, also in application I added same jar from the same location. Still am facing the issue. I referred all links WSJDBCConnection does not wrap objects of type oracle.jdbc.OracleConnection like this. Still am facing the same issue.
In order for Connection.unwrap to work properly, the Liberty DataSource and the Application must both load the vendor implementation class (oracle.jdbc.OracleConnection) from the same class loader.
Here is a simple example of how to configure both the dataSource and your application to use the same class loader to load from a single library that contains the Oracle JDBC driver,
<library id="OracleLib">
<fileset dir="${server.config.dir}/oracle"/>
</library>
<application location="myApp.war" >
<classloader commonLibraryRef="OracleLib"/>
</application>
<dataSource jndiName="jdbc/oracleDataSource">
<jdbcDriver libraryRef="OracleLib"/>
<properties.oracle .../>
</dataSource>
