C3P0NativeJdbcExtractor

Class Overview

Implementation of the NativeJdbcExtractor interface for the C3P0 connection pool.

Returns underlying native Connections to application code instead of C3P0's wrapper implementations; unwraps the Connection for native Statements. The returned JDBC classes can then safely be cast, e.g. to oracle.jdbc.OracleConnection.

This NativeJdbcExtractor can be set just to allow working with a C3P0 DataSource: If a given object is not a C3P0 wrapper, it will be returned as-is.

Note that this class requires C3P0 0.8.5 or later; for earlier C3P0 versions, use SimpleNativeJdbcExtractor (which won't work for C3P0 0.8.5 or later).
