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 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

Field Summary

private java.lang.reflect.Method	getVendorConnectionMethod
private static java.lang.String	JDBC_EXTENSION_NAME
private java.lang.Class	jdbcExtensionClass

Constructor Summary

WebLogicNativeJdbcExtractor()
This constructor retrieves the WebLogic JDBC extension interface, 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 WebLogic's getVendorConnection method.
boolean	isNativeConnectionNecessaryForNativeCallableStatements() Return true, as WebLogic returns wrapped CallableStatements.
boolean	isNativeConnectionNecessaryForNativePreparedStatements() Return true, as WebLogic returns wrapped PreparedStatements.
boolean	isNativeConnectionNecessaryForNativeStatements() Return true, as WebLogic returns wrapped Statements.
