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

Method Summary
