## Class ActiveMQConnection

- java.lang.Object
- - org.apache.activemq.artemis.jms.client.ActiveMQConnectionForContextImpl
  - - org.apache.activemq.artemis.jms.client.ActiveMQConnection

- All Implemented Interfaces:
    AutoCloseable, javax.jms.Connection, javax.jms.QueueConnection, javax.jms.TopicConnection, ActiveMQConnectionForContext
  Direct Known Subclasses:
    ActiveMQXAConnection

      public class ActiveMQConnection
      extends ActiveMQConnectionForContextImpl
      implements javax.jms.TopicConnection, javax.jms.QueueConnection

  ActiveMQ Artemis implementation of a JMS Connection.

  The flat implementation of `TopicConnection` and `QueueConnection` is per design, following the common usage of these as one flat API in JMS 1.1.

    - #### createNonXASession

          public javax.jms.Session createNonXASession(boolean transacted,
                                                      int acknowledgeMode)
                                               throws javax.jms.JMSException

      This internal method serves basically the Resource Adapter. The resource adapter plays with an XASession and a non XASession. When there is no enlisted transaction, the EE specification mandates that the commit should be done as if it was a nonXA Session (i.e. SessionTransacted). For that reason we have this method to force that nonXASession, since the JMS Javadoc mandates createSession to return a XASession.
      Throws:
        `javax.jms.JMSException`
