org.apache.xmlbeans.impl.soap
Class MessageFactory  

java.lang.Object
  org.apache.xmlbeans.impl.soap.MessageFactory

---

public abstract class MessageFactory

extends java.lang.Object

A factory for creating SOAPMessage objects.

A JAXM client performs the following steps to create a message.

• Creates a MessageFactory object from a ProviderConnection object (con in the following line of code). The String passed to the createMessageFactory method is the name of of a messaging profile, which must be the URL for the schema.

        MessageFactory mf = con.createMessageFactory(schemaURL);
   

• Calls the method createMessage on the MessageFactory object. All messages produced by this MessageFactory object will have the header information appropriate for the messaging profile that was specified when the MessageFactory object was created.

        SOAPMessage m = mf.createMessage();
   

It is also possible to 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

If a MessageFactory object was created using a ProviderConnection object, which means that it was initialized with a specified profile, 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.

Constructor Detail

MessageFactory

public MessageFactory()

Create a new MessageFactory.

Method Detail

newInstance

public static MessageFactory newInstance()
                                  throws SOAPException

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

---

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.

createMessage

public abstract SOAPMessage createMessage(MimeHeaders mimeheaders,
                                          java.io.InputStream inputstream)
                                   throws java.io.IOException,
                                          SOAPException

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