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

Implementation of the NativeJdbcExtractor interface for WebSphere, supporting WebSphere Application Server 5.1 and higher.

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.

Since:

1.1

Constructor Summary

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

Method Summary

protected java.sql.Connection	doGetNativeConnection(java.sql.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.
