   org.springframework.jca.cci.connection.ConnectionFactoryUtils

ConnectionFactoryUtils
abstract public class ConnectionFactoryUtils (Code)
Helper class that provides static methods for obtaining CCI Connections from a javax.resource.cci.ConnectionFactory . Includes special support for Spring-managed transactional Connections, e.g. managed by CciLocalTransactionManager or org.springframework.transaction.jta.JtaTransactionManager .

Used internally by org.springframework.jca.cci.core.CciTemplate , Spring's CCI operation objects and the CciLocalTransactionManager . Can also be used directly in application code.

See Also:   org.springframework.transaction.jta.JtaTransactionManager
See Also:   org.springframework.transaction.support.TransactionSynchronizationManager





Method Summary
public static  ConnectiondoGetConnection(ConnectionFactory cf)
     Actually obtain a CCI Connection from the given ConnectionFactory. Same as ConnectionFactoryUtils.getConnection , but throwing the original ResourceException.

Is aware of a corresponding Connection bound to the current thread, for example when using CciLocalTransactionManager .

public static  voiddoReleaseConnection(Connection con, ConnectionFactory cf)
     Actually close the given Connection, obtained from the given ConnectionFactory.
public static  ConnectiongetConnection(ConnectionFactory cf)
     Obtain a Connection from the given ConnectionFactory.
public static  ConnectiongetConnection(ConnectionFactory cf, ConnectionSpec spec)
     Obtain a Connection from the given ConnectionFactory.
public static  booleanisConnectionTransactional(Connection con, ConnectionFactory cf)
     Determine whether the given JCA CCI Connection is transactional, that is, bound to the current thread by Spring's transaction facilities.
public static  voidreleaseConnection(Connection con, ConnectionFactory cf)
     Close the given Connection, obtained from the given ConnectionFactory, if it is not managed externally (that is, not bound to the thread).



Method Detail
doGetConnection
public static Connection doGetConnection(ConnectionFactory cf) throws ResourceException(Code)
Actually obtain a CCI Connection from the given ConnectionFactory. Same as ConnectionFactoryUtils.getConnection , but throwing the original ResourceException.

Is aware of a corresponding Connection bound to the current thread, for example when using CciLocalTransactionManager . Will bind a Connection to the thread if transaction synchronization is active (e.g. if in a JTA transaction).

Directly accessed by TransactionAwareConnectionFactoryProxy .
Parameters:
  cf - the ConnectionFactory to obtain Connection from a CCI Connection from the given ConnectionFactory
throws:
  ResourceException - if thrown by CCI API methods
See Also:   ConnectionFactoryUtils.doReleaseConnection




doReleaseConnection
public static void doReleaseConnection(Connection con, ConnectionFactory cf) throws ResourceException(Code)
Actually close the given Connection, obtained from the given ConnectionFactory. Same as ConnectionFactoryUtils.releaseConnection , but throwing the original ResourceException.

Directly accessed by TransactionAwareConnectionFactoryProxy .
Parameters:
  con - the Connection to close if necessary(if this is null, the call will be ignored)
Parameters:
  cf - the ConnectionFactory that the Connection was obtained from(can be null)
throws:
  ResourceException - if thrown by JCA CCI methods
See Also:   ConnectionFactoryUtils.doGetConnection




getConnection
public static Connection getConnection(ConnectionFactory cf) throws CannotGetCciConnectionException(Code)
Obtain a Connection from the given ConnectionFactory. Translates ResourceExceptions into the Spring hierarchy of unchecked generic data access exceptions, simplifying calling code and making any exception that is thrown more meaningful.

Is aware of a corresponding Connection bound to the current thread, for example when using CciLocalTransactionManager . Will bind a Connection to the thread if transaction synchronization is active (e.g. if in a JTA transaction).
Parameters:
  cf - the ConnectionFactory to obtain Connection from a CCI Connection from the given ConnectionFactory
throws:
  org.springframework.jca.cci.CannotGetCciConnectionException - if the attempt to get a Connection failed
See Also:   ConnectionFactoryUtils.releaseConnection




getConnection
public static Connection getConnection(ConnectionFactory cf, ConnectionSpec spec) throws CannotGetCciConnectionException(Code)
Obtain a Connection from the given ConnectionFactory. Translates ResourceExceptions into the Spring hierarchy of unchecked generic data access exceptions, simplifying calling code and making any exception that is thrown more meaningful.

Is aware of a corresponding Connection bound to the current thread, for example when using CciLocalTransactionManager . Will bind a Connection to the thread if transaction synchronization is active (e.g. if in a JTA transaction).
Parameters:
  cf - the ConnectionFactory to obtain Connection from
Parameters:
  spec - the ConnectionSpec for the desired Connection (may be null).Note: If this is specified, a new Connection will be obtained for every call,without participating in a shared transactional Connection. a CCI Connection from the given ConnectionFactory
throws:
  org.springframework.jca.cci.CannotGetCciConnectionException - if the attempt to get a Connection failed
See Also:   ConnectionFactoryUtils.releaseConnection




isConnectionTransactional
public static boolean isConnectionTransactional(Connection con, ConnectionFactory cf)(Code)
Determine whether the given JCA CCI Connection is transactional, that is, bound to the current thread by Spring's transaction facilities.
Parameters:
  con - the Connection to check
Parameters:
  cf - the ConnectionFactory that the Connection was obtained from(may be null) whether the Connection is transactional



releaseConnection
public static void releaseConnection(Connection con, ConnectionFactory cf)(Code)
Close the given Connection, obtained from the given ConnectionFactory, if it is not managed externally (that is, not bound to the thread).
Parameters:
  con - the Connection to close if necessary(if this is null, the call will be ignored)
Parameters:
  cf - the ConnectionFactory that the Connection was obtained from(can be null)
See Also:   ConnectionFactoryUtils.getConnection
