      org.springframework.jdbc.support.nativejdbc.JBossNativeJdbcExtractor

All Implemented Interfaces:

NativeJdbcExtractor

public class JBossNativeJdbcExtractor

extends NativeJdbcExtractorAdapter

Implementation of the NativeJdbcExtractor interface for the JBoss 3.2 connection pool. 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 OracleConnection.

Note that JBoss started wrapping ResultSets as of 3.2.4, which is supported by this implementation, while still being compatible with 3.2.x

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.

Constructor Summary

JBossNativeJdbcExtractor()
This constructor retrieves JBoss JDBC wrapper classes, so we can get the underlying vendor connection using reflection.

Method Summary

protected Connection	doGetNativeConnection(Connection con) Retrieve the Connection via JBoss' getUnderlyingConnection method.
CallableStatement	getNativeCallableStatement(CallableStatement cs) Retrieve the Connection via JBoss' getUnderlyingStatement method.
PreparedStatement	getNativePreparedStatement(PreparedStatement ps) Retrieve the Connection via JBoss' getUnderlyingStatement method.
ResultSet	getNativeResultSet(ResultSet rs) Retrieve the Connection via JBoss' getUnderlyingResultSet method.
Statement	getNativeStatement(Statement stmt) Retrieve the Connection via JBoss' getUnderlyingStatement method.

public JBossNativeJdbcExtractor()

This constructor retrieves JBoss JDBC wrapper classes, so we can get the underlying vendor connection using reflection.

Method Detail

doGetNativeConnection

protected Connection doGetNativeConnection(Connection con)
                                    throws SQLException

Retrieve the Connection via JBoss' getUnderlyingConnection method.

Overrides:

doGetNativeConnection in class NativeJdbcExtractorAdapter

Throws:

SQLException

getNativeStatement

public Statement getNativeStatement(Statement stmt)
                             throws SQLException

Retrieve the Connection via JBoss' getUnderlyingStatement method.

Specified by:

getNativeStatement in interface NativeJdbcExtractor

Overrides:

getNativeStatement in class NativeJdbcExtractorAdapter

Throws:

SQLException

getNativePreparedStatement

public PreparedStatement getNativePreparedStatement(PreparedStatement ps)
                                             throws SQLException

Retrieve the Connection via JBoss' getUnderlyingStatement method.

Specified by:

getNativePreparedStatement in interface NativeJdbcExtractor

Overrides:

getNativePreparedStatement in class NativeJdbcExtractorAdapter

Throws:

SQLException

getNativeCallableStatement

public CallableStatement getNativeCallableStatement(CallableStatement cs)
                                             throws SQLException

Retrieve the Connection via JBoss' getUnderlyingStatement method.

Specified by:

getNativeCallableStatement in interface NativeJdbcExtractor

Overrides:

getNativeCallableStatement in class NativeJdbcExtractorAdapter

Throws:

SQLException

getNativeResultSet

public ResultSet getNativeResultSet(ResultSet rs)
                             throws SQLException

Retrieve the Connection via JBoss' getUnderlyingResultSet method.

We access WrappedResultSet via direct reflection, since this class only appeared in JBoss 3.2.4 and we want to stay compatible with at least 3.2.2+.

Specified by:

getNativeResultSet in interface NativeJdbcExtractor

Overrides:

getNativeResultSet in class NativeJdbcExtractorAdapter

Throws:

SQLException
