## javax.xml.messaging
Class ProviderConnectionFactory

    java.lang.Object
      javax.xml.messaging.ProviderConnectionFactory

    public abstract class ProviderConnectionFactory

extends Object

A factory for creating connections to a particular messaging provider. A `ProviderConnectionFactory` object can be obtained in two different ways.

- Call the `ProviderConnectionFactory.newInstance` method to get an instance of the default `ProviderConnectionFactory` object.
  This instance can be used to create a `ProviderConnection` object that connects to the default provider implementation.

            ProviderConnectionFactory pcf = ProviderConnectionFactory.newInstance();
            ProviderConnection con = pcf.createConnection();

- Retrieve a `ProviderConnectionFactory` object that has been registered with a naming service based on Java Naming and Directory InterfaceTM (JNDI) technology.
  In this case, the `ProviderConnectionFactory` object is an administered object that was created by a container (a servlet or Enterprise JavaBeansTM container). The `ProviderConnectionFactory` object was configured in an implementation- specific way, and the connections it creates will be to the specified messaging provider.

  Registering a `ProviderConnectionFactory` object with a JNDI naming service associates it with a logical name. When an application wants to establish a connection with the provider associated with that `ProviderConnectionFactory` object, it does a lookup, providing the logical name. The application can then use the `ProviderConnectionFactory` object that is returned to create a connection to the messaging provider. The first two lines of the following code fragment use JNDI methods to retrieve a `ProviderConnectionFactory` object. The third line uses the returned object to create a connection to the JAXM provider that was registered with "ProviderXYZ" as its logical name.

            Context ctx = new InitialContext();
            ProviderConnectionFactory pcf = (ProviderConnectionFactory)ctx.lookup(
                                                                       "ProviderXYZ");
            ProviderConnection con = pcf.createConnection();
