Class MessageFactory

java.lang.Object
  javax.xml.soap.MessageFactory

public abstract class MessageFactory
extends Object

A factory for creating SOAPMessage objects. A SAAJ client can create a MessageFactory object using the method newInstance, as shown in the following line of code. MessageFactory mf = MessageFactory.newInstance(); A standalone client (a client that is not running in a container) can use the newInstance method to create a MessageFactory object. All MessageFactory objects, regardless of how they are created, will produce SOAPMessage objects that have the following elements by default: A SOAPPart object A SOAPEnvelope object A SOAPBody object A SOAPHeader object MessageFactory objects can be initialized with a JAXM profile. In such a case it will produce messages that also come prepopulated with additional entries in the SOAPHeader object and the SOAPBody object. The content of a new SOAPMessage object depends on which of the two MessageFactory methods is used to create it. createMessage() -- message has no content This is the method clients would normally use to create a request message. createMessage(MimeHeaders, java.io.InputStream) -- message has content from the InputStream object and headers from the MimeHeaders object This method can be used internally by a service implementation to create a message that is a response to a request.

Method Detail

newInstance

public static MessageFactory newInstance()
                                  throws SOAPException

Creates a new MessageFactory object that is an instance of the default implementation.

Throws:

SOAPException

createMessage

public abstract SOAPMessage createMessage()
                                   throws SOAPException

Creates a new SOAPMessage object with the default SOAPPart, SOAPEnvelope, SOAPBody, and SOAPHeader objects. Profile-specific message factories can choose to prepopulate the SOAPMessage object with profile-specific headers. Content can be added to this message's SOAPPart object, and the message can be sent "as is" when a message containing only a SOAP part is sufficient. Otherwise, the SOAPMessage object needs to create one or more AttachmentPart objects and add them to itself. Any content that is not in XML format must be in an AttachmentPart object.

Returns:

a new SOAPMessage object

Throws:

SOAPException - if a SOAP error occurs

createMessage

public abstract SOAPMessage createMessage(MimeHeaders headers,
                                          InputStream in)
                                   throws IOException,
                                          SOAPException

Internalizes the contents of the given InputStream object into a new SOAPMessage object and returns the SOAPMessage object.

Parameters:

headers - the transport-specific headers passed to the message in a transport-independent fashion for creation of the message

in - the InputStream object that contains the data for a message

Returns:

a new SOAPMessage object containing the data from the given InputStream object

Throws:

IOException - if there is a problem in reading data from the input stream

SOAPException - if the message is invalid
