Class WebLogicNativeJdbcExtractor

java.lang.Object
  extended by org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractorAdapter
      extended by 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 8.1 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.

Since:
1.0.2
