javax.xml.soap
public abstract class SOAPMessage extends Object
The root class for all SOAP messages. As transmitted on the "wire", a SOAP message is an XML document or a MIME message whose first body part is an XML/SOAP document.
A SOAPMessage object consists of a SOAP part
and optionally one or more attachment parts. The SOAP part for
a SOAPMessage object is a SOAPPart
object, which contains information used for message routing and
identification, and which can contain application-specific
content. All data in the SOAP Part of a message must be in XML
format.
A new SOAPMessage object contains the following
by default:
SOAPPart objectSOAPEnvelope objectSOAPBody objectSOAPHeader objectSOAPMessage.getSOAPPart(). The
SOAPEnvelope object is retrieved from the
SOAPPart object, and the SOAPEnvelope
object is used to retrieve the SOAPBody and
SOAPHeader objects.
SOAPPart sp = message.getSOAPPart(); SOAPEnvelope se = sp.getEnvelope(); SOAPBody sb = se.getBody(); SOAPHeader sh = se.getHeader();
In addition to the mandatory SOAPPart object, a
SOAPMessage object may contain zero or more
AttachmentPart objects, each of which contains
application-specific data. The SOAPMessage
interface provides methods for creating
AttachmentPart objects and also for adding them to a
SOAPMessage object. A party that has received a
SOAPMessage object can examine its contents by
retrieving individual attachment parts.
Unlike the rest of a SOAP message, an attachment is not
required to be in XML format and can therefore be anything from
simple text to an image file. Consequently, any message content
that is not in XML format must be in an
AttachmentPart object.
A MessageFactory object creates new
SOAPMessage objects. If the MessageFactory
object was initialized with a messaging Profile, it produces
SOAPMessage objects that conform to that Profile.
For example, a SOAPMessage object created by a
MessageFactory object initialized with the ebXML
Profile will have the appropriate ebXML headers.

AttachmentPart object to this
SOAPMessage object. An
AttachmentPart object must be created before it can be
added to a message.Parameters: attachmentpart an
AttachmentPart object that is to become part of
this SOAPMessage object
Throws: java.lang.IllegalArgumentException
Returns: the number of AttachmentPart objects
that are part of this SOAPMessage
object
AttachmentPart object.
Note that the method addAttachmentPart must be
called with this new AttachmentPart object as
the parameter in order for it to become an attachment to this
SOAPMessage object.Returns: a new AttachmentPart object that can be
populated and added to this SOAPMessage
object
AttachmentPart object and
populates it using the given DataHandler
object.Parameters: datahandler the
javax.activation.DataHandler object that will
generate the content for this SOAPMessage
object
Returns: a new AttachmentPart object that
contains data generated by the given
DataHandler object
Throws: java.lang.IllegalArgumentException if
there was a problem with the specified
DataHandler object
See Also: DataHandler DataHandler javax.activation.DataContentHandler DataContentHandler
AttachmentPart object and
populates it with the specified data of the specified content
type.Parameters: content an Object
containing the content for this SOAPMessage
object contentType a String
object giving the type of content; examples are
"text/xml", "text/plain", and "image/jpeg"
Returns: a new AttachmentPart object that
contains the given data
Throws: java.lang.IllegalArgumentException if the contentType does not match the type of the content

If a SOAPMessage object contains one or
more attachments, the SOAP Part must be the first MIME body
part in the message.
Returns: the SOAPPart object for this

AttachmentPart objects that have
been added to this SOAPMessage object.
This method does not touch the SOAP part.
SOAPMessage object with all the
changes that have been made to it. This method is called
automatically when a message is sent or written to by the
methods ProviderConnection.send,
SOAPConnection.call, or
SOAPMessage.writeTo. However, if changes are made to
a message that was received or to one that has already been
sent, the method saveChanges needs to be
called explicitly in order to save the changes. The method
saveChanges also generates any changes that
can be read back (for example, a MessageId in profiles that
support a message id). All MIME headers in a message that
is created for sending purposes are guaranteed to have
valid values only after saveChanges has been
called.
In addition, this method marks the point at which the
data from all constituent AttachmentPart
objects are pulled into the message.
Throws: SOAPException if there was a problem saving changes to this message.
SOAPMessage object
has had the method saveChanges called on
it.Returns: true if saveChanges has
been called on this message at least once;
false otherwise.
SOAPMessage
object's content with the given description.Parameters: description a String
describing the content of this message
See Also: getContentDescription()
The valid property names include WRITE_XML_DECLARATION and
CHARACTER_SET_ENCODING. All of these standard SAAJ
properties are prefixed by "javax.xml.soap". Vendors may also add
implementation specific properties. These properties must be prefixed
with package names that are unique to the vendor.
Setting the property WRITE_XML_DECLARATION to
"true" will cause an XML Declaration to be written out at
the start of the SOAP message. The default value of "false" suppresses
this declaration.
The property CHARACTER_SET_ENCODING defaults to the value
"utf-8" which causes the SOAP message to be encoded using
UTF-8. Setting CHARACTER_SET_ENCODING to
"utf-16" causes the SOAP message to be encoded using UTF-16.
Some implementations may allow encodings in addition to UTF-8 and UTF-16. Refer to your vendor's documentation for details.
Parameters: property the property with which the specified value is to be associated value the value to be associated with the specified property
Throws: SOAPException if the property name is not recognized
SOAPMessage object to the given
output stream. The externalization format is as defined by
the SOAP 1.1 with Attachments specification.
If there are no attachments, just an XML stream is
written out. For those messages that have attachments,
writeTo writes a MIME-encoded byte stream.
Parameters: out the OutputStream
object to which this SOAPMessage object will
be written
Throws: SOAPException if there was a problem in externalizing this SOAP message IOException if an I/O error occurs
