Usage

From source file:org.springframework.jca.cci.connection.ConnectionFactoryUtils.java

/**
 * 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.
 * <p>Is aware of a corresponding Connection bound to the current thread, for example
 * when using {@link CciLocalTransactionManager}. Will bind a Connection to the thread
 * if transaction synchronization is active (e.g. if in a JTA transaction).
 * @param cf the ConnectionFactory to obtain Connection from
 * @param spec the ConnectionSpec for the desired Connection (may be {@code null}).
 * Note: If this is specified, a new Connection will be obtained for every call,
 * without participating in a shared transactional Connection.
 * @return a CCI Connection from the given ConnectionFactory
 * @throws org.springframework.jca.cci.CannotGetCciConnectionException
 * if the attempt to get a Connection failed
 * @see #releaseConnection/* w  w  w  . jav a 2  s  .  c om*/
