MessageFactory JDK 1.6)

Description

publicabstract abstract class MessageFactory

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:

A SOAPPart object
A SOAPEnvelope object
A SOAPBody object
A SOAPHeader object

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.

createMessage()
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.

publicabstract SOAPMessage createMessage () throws SOAPException

Creates a new SOAPMessage object with the default SOAPPart, SOAPEnvelope, SOAPBody, and SOAPHeader objects.

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

publicabstract 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.

Internalizes the contents of the given InputStream object into a
new SOAPMessage object and returns the SOAPMessage
object.
Returns: a new SOAPMessage object containing the data from the given InputStream 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
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.

publicstatic 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.

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.

publicstatic MessageFactory newInstance (String protocol) throws SOAPException

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

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.
Returns: a new instance of a MessageFactory
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.
Throws:
- SOAPException - if there was an error in creating the specified implementation of MessageFactory.
