### Question:
ActiveMQConnectionFactory implements ConnectionFactory, QueueConnectionFactory, TopicConnectionFactory, Referenceable, Serializable { public Connection createConnection() throws JMSException { return createConnection(info.copy()); } ActiveMQConnectionFactory(
            ActiveMQManagedConnectionFactory factory, 
            ConnectionManager manager, 
            ActiveMQConnectionRequestInfo connectionRequestInfo); Connection createConnection(); Connection createConnection(String userName, String password); Reference getReference(); void setReference(Reference reference); QueueConnection createQueueConnection(); QueueConnection createQueueConnection(String userName, String password); TopicConnection createTopicConnection(); TopicConnection createTopicConnection(String userName, String password);  }### Answer:
@Test(timeout = 60000) public void testSerializability() throws Exception { ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(mcf, new ConnectionManagerAdapter(), info); ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(bos); oos.writeObject(factory); oos.close(); byte[] byteArray = bos.toByteArray(); ObjectInputStream ois = new ObjectInputStream(new ByteArrayInputStream(byteArray)); ActiveMQConnectionFactory deserializedFactory = (ActiveMQConnectionFactory) ois.readObject(); ois.close(); Connection con = deserializedFactory.createConnection("defaultUser", "defaultPassword"); ActiveMQConnection connection = ((ActiveMQConnection) ((ManagedConnectionProxy) con).getManagedConnection().getPhysicalConnection()); assertEquals(100, connection.getPrefetchPolicy().getQueuePrefetch()); assertNotNull("Connection object returned by ActiveMQConnectionFactory.createConnection() is null", con); connection.close(); }
