Class XAPoolNativeJdbcExtractor

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

All Implemented Interfaces:: NativeJdbcExtractor

public class XAPoolNativeJdbcExtractor
extends NativeJdbcExtractorAdapter
extends NativeJdbcExtractorAdapter

Implementation of the NativeJdbcExtractor interface for ObjectWeb's XAPool, as shipped with JOTM and used in JOnAS.

Returns underlying native Connections and native PreparedStatements to application code instead of XAPool's wrapper implementations; unwraps the Connection for native Statements and native CallableStatements. 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 an XAPool DataSource: If a given object is not an XAPool wrapper, it will be returned as-is.
