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 Server. 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 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.

Currently only tested with BEA WebLogic 8.1 SP2.

Since:

1.0.2
