Java javax.xml.soap Class MessageFactory（JDK8）

Constructor Detail

• MessageFactory

  public MessageFactory()

Method Detail

• newInstance

  public static MessageFactory newInstance()
                                    throws SOAPException

  Creates a new MessageFactory object that is an instance of the default implementation (SOAP 1.1), This method uses the following ordered lookup procedure to determine the MessageFactory implementation class to load:

  • Use the javax.xml.soap.MessageFactory system property.
  • Use the properties file "lib/jaxm.properties" in the JRE directory. This configuration file is in standard java.util.Properties format and contains the fully qualified name of the implementation class with the key being the system property defined above.
  • Use the Services API (as detailed in the JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.soap.MessageFactory in jars available to the runtime.
  • Use the SAAJMetaFactory instance to locate the MessageFactory implementation class.

  Returns:

  a new instance of a MessageFactory

  Throws:

  SOAPException - if there was an error in creating the default implementation of the MessageFactory.

  SAAJMetaFactory

• newInstance

  public static MessageFactory newInstance(String protocol)
                                    throws SOAPException

  Creates a new MessageFactory object that is an instance of the specified implementation. May be a dynamic message factory, a SOAP 1.1 message factory, or a SOAP 1.2 message factory. A dynamic message factory creates messages based on the MIME headers specified as arguments to the createMessage method. This method uses the SAAJMetaFactory to locate the implementation class and create the MessageFactory instance.

  Parameters:

  protocol - a string constant representing the class of the specified message factory implementation. May be either DYNAMIC_SOAP_PROTOCOL, DEFAULT_SOAP_PROTOCOL (which is the same as) SOAP_1_1_PROTOCOL, or SOAP_1_2_PROTOCOL.

  Returns:

  a new instance of a MessageFactory

  Throws:

  SOAPException - if there was an error in creating the specified implementation of MessageFactory.

  Since:

  SAAJ 1.3

• 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

  UnsupportedOperationException - if the protocol of this MessageFactory instance is DYNAMIC_SOAP_PROTOCOL

• 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:

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

  headers - the transport-specific headers passed to the message in a transport-independent fashion for creation of the 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 - may be thrown if the message is invalid

  IllegalArgumentException - if the MessageFactory requires one or more MIME headers to be present in the headers parameter and they are missing. MessageFactory implementations for SOAP_1_1_PROTOCOL or SOAP_1_2_PROTOCOL must not throw IllegalArgumentException for this reason.
