SOAPConnectionFactory

SOAPConnectionFactory is a class in the Java API for XML Messaging (JAX-WS), which is part of the Java EE (now Jakarta EE) platform. It is used to create SOAPConnection objects. A SOAPConnection is a client-side object that allows an application to send a SOAP message to a specific endpoint and receive a SOAP message in response. The SOAPConnectionFactory is responsible for providing instances of SOAPConnection.

To obtain a SOAPConnectionFactory, one typically calls the static factory method `SOAPConnectionFactory.newInstance()`. This method returns a new SOAPConnectionFactory object. The actual implementation returned may vary depending on the underlying JAX-WS provider.

Once a SOAPConnectionFactory is obtained, you can create a SOAPConnection by calling the `createConnection()` method on the factory instance. This SOAPConnection object is then used to send and receive SOAP messages. For example, you might use its `call()` method, passing in a SOAPMessage object representing the outgoing request, to send it to a service endpoint and receive the SOAPMessage response. The SOAPConnection should be closed when it is no longer needed to release any associated resources.
