## Class WebLogicNativeJdbcExtractor

- java.lang.Object
- - org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractorAdapter
  - - org.springframework.jdbc.support.nativejdbc.WebLogicNativeJdbcExtractor

- All Implemented Interfaces:
    NativeJdbcExtractor

      public class WebLogicNativeJdbcExtractor
      extends NativeJdbcExtractorAdapter

  Implementation of the `NativeJdbcExtractor` interface for WebLogic, supporting WebLogic Server 9.0 and higher.

  Returns the underlying native Connection to application code instead of WebLogic's wrapper implementation; 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 WebLogic DataSource: If a given object is not a WebLogic Connection wrapper, it will be returned as-is.

    1.0.2
