Class JBossNativeJdbcExtractor

java.lang.Object
  extended by org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractorAdapter
      extended by org.springframework.jdbc.support.nativejdbc.JBossNativeJdbcExtractor
All Implemented Interfaces:
NativeJdbcExtractor

public class JBossNativeJdbcExtractor
extends NativeJdbcExtractorAdapter

Implementation of the NativeJdbcExtractor interface for JBoss, supporting JBoss Application Server 3.2.4+. As of Spring 3.1.1, it also supports JBoss 7.

Returns the underlying native Connection, Statement, etc to application code instead of JBoss' wrapper implementations. 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 JBoss connection pool: If a given object is not a JBoss wrapper, it will be returned as-is.
