Interface XAConnectionFactory

All Known Subinterfaces:
  XAQueueConnectionFactory, XATopicConnectionFactory

All Known Implementing Classes:
  XAConnectionFactory, XAQueueConnectionFactory, XATopicConnectionFactory

public interface XAConnectionFactory

The `XAConnectionFactory` interface is a base interface for the `XAQueueConnectionFactory` and `XATopicConnectionFactory` interfaces.

Some application servers provide support for grouping JTS capable resource use into a distributed transaction (optional). To include JMS API transactions in a JTS transaction, an application server requires a JTS aware JMS provider. A JMS provider exposes its JTS support using an `XAConnectionFactory` object, which an application server uses to create `XAConnection` objects.

`XAConnectionFactory` objects are JMS administered objects, just like `ConnectionFactory` objects. It is expected that application servers will find them using the Java Naming and Directory Interface (JNDI) API.

The `XAConnectionFactory` interface is optional. JMS providers are not required to support this interface. This interface is for use by JMS providers to support transactional environments. Client programs are strongly encouraged to use the transactional support available in their environment, rather than use these XA interfaces directly.
