Class WebSphereNativeJdbcExtractor

java.lang.Object
  org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractorAdapter
      org.springframework.jdbc.support.nativejdbc.WebSphereNativeJdbcExtractor

All Implemented Interfaces:: NativeJdbcExtractor

public class WebSphereNativeJdbcExtractor
extends NativeJdbcExtractorAdapter
extends NativeJdbcExtractorAdapter

Implementation of the NativeJdbcExtractor interface for WebSphere.

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

Supports both WebSphere 5 and WebSphere 4. Currently tested with IBM WebSphere 5.1.0, 5.0.2 and 4.0.6. Thanks to Dave Keller and Victor for figuring out how to do the unwrapping on WebSphere 5 and 4!

Field Summary

protected Log logger


Constructor Summary

WebSphereNativeJdbcExtractor()
          This constructor retrieves WebSphere JDBC adapter classes, so we can get the underlying vendor connection using reflection.

Method Summary

protected Connection doGetNativeConnection(Connection con)
          Retrieve the Connection via WebSphere's getNativeConnection method.

boolean isNativeConnectionNecessaryForNativeCallableStatements()
          Return true, as WebSphere returns wrapped CallableStatements.

boolean isNativeConnectionNecessaryForNativePreparedStatements()
          Return true, as WebSphere returns wrapped PreparedStatements.

boolean isNativeConnectionNecessaryForNativeStatements()
          Return true, as WebSphere returns wrapped Statements.
