 java.sql.Connection getConnection()
          This implementation delegates to the underlying DataSource.
 javax.sql.DataSource getDataSource()
          Return the DataSource that this ConnectionProvider wraps.
protected  javax.sql.DataSource getDataSourceToUse(javax.sql.DataSource originalDataSource)
          Return the DataSource to use for retrieving Connections.
 boolean supportsAggressiveRelease()
          This implementation returns false: We cannot guarantee to receive the same Connection within a transaction, not even when dealing with a JNDI DataSource.
