Method Summary
 void close()
          This implementation does nothing: We're dealing with an externally managed DataSource.
 void closeConnection(Connection con)

 void configure(Properties props)
           
 Connection getConnection()
          This implementation delegates to the underlying DataSource.
 DataSource getDataSource()
          Return the DataSource that this ConnectionProvider wraps.
protected  DataSource getDataSourceToUse(DataSource originalDataSource)
