javax.xml.soap
Class MessageFactory

java.lang.Object
  extended by 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 lines of code.

       MessageFactory mf = MessageFactory.newInstance();
       MessageFactory mf12 = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
 

All MessageFactory objects, regardless of how they are created, will produce SOAPMessage objects that have the following elements by default:

In some cases, specialized MessageFactory objects may be obtained that produce messages 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.

MessageFactory()
           
 
Method Summary
abstract  SOAPMessage createMessage()
          Creates a new SOAPMessage object with the default SOAPPart, SOAPEnvelope, SOAPBody, and SOAPHeader objects.
abstract  SOAPMessage createMessage(MimeHeaders headers, InputStream in)
          Internalizes the contents of the given InputStream object into a new SOAPMessage object and returns the SOAPMessage object.
static MessageFactory newInstance()
          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.
static MessageFactory newInstance(String protocol)
          Creates a new MessageFactory object that is an instance of the specified implementation.

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:

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.
