Class SimpleNativeJdbcExtractor

public class SimpleNativeJdbcExtractor

implements NativeJdbcExtractor

Simple implementation of the NativeJdbcExtractor interface. Assumes a pool that just wraps Connections but not Statements/ResultSets: In this case, the underlying native Connection can be retrieved by simply opening a Statement and invoking Statement.getConnection(). All other JDBC objects will be returned as passed in.

Known to work with Resin 2.1 and C3P0, but should work with any pool that does not wrap Statements and ResultSets, or at least returns the native Connection on Statement.getConnection.

public void setNativeConnectionNecessaryForNativeCallableStatements(boolean nativeConnectionNecessary)

Set whether it is necessary to work on the native Connection to receive native CallableStatements. Default is false.

This makes sense if you need to work with native Statements/ResultSets from a pool that does not allow to extract the native JDBC objects from its wrappers but returns the native Connection on Statement.getConnection, like C3P0.
