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
object SOAPEnvelope
object SOAPBody
object SOAPHeader
object SOAPMessage.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 may create SOAPMessage
objects with behavior that is specialized to a particular implementation or application of SAAJ. For instance, a MessageFactory
object may produce SOAPMessage
objects that conform to a particular Profile such as ebXML. In this case a MessageFactory
object might produce SOAPMessage
objects that are initialized with ebXML headers.
In order to ensure backward source compatibility, methods that are added to this class after version 1.1 of the SAAJ specification are all concrete instead of abstract and they all have default implementations. Unless otherwise noted in the JavaDocs for those methods the default implementations simply throw an UnsupportedOperationException
and the SAAJ implementation code must override them with methods that provide the specified behavior. Legacy client code does not have this restriction, however, so long as there is no claim made that it conforms to some later version of the specification than it was originally written for. A legacy class that extends the SOAPMessage class can be compiled and/or run against succeeding versions of the SAAJ API without modification. If such a class was correctly implemented then it will continue to behave correctly relative to the version of the specification against which it was written.

object.

Removes all AttachmentPart
objects that have been added to this SOAPMessage
object.
This method does not touch the SOAP part.
public abstract int countAttachments()
Gets a count of the number of attachments in this message. This count does not include the SOAP part.
AttachmentPart
objects that are part of this SOAPMessage
objectpublic abstract Iterator getAttachments()
Retrieves all the AttachmentPart
objects that are part of this SOAPMessage
object.
public abstract Iterator getAttachments(MimeHeaders headers)
Retrieves all the AttachmentPart
objects that have header entries that match the specified headers. Note that a returned attachment could have headers in addition to those specified.
headers
- a MimeHeaders
object containing the MIME headers for which to searchpublic abstract void removeAttachments(MimeHeaders headers)
Removes all the AttachmentPart
objects that have header entries that match the specified headers. Note that the removed attachment could have headers in addition to those specified.
headers
- a MimeHeaders
object containing the MIME headers for which to searchpublic abstract AttachmentPart getAttachment(SOAPElement element) throws SOAPException
Returns an AttachmentPart
object that is associated with an attachment that is referenced by this SOAPElement
or null
if no such attachment exists. References can be made via an href
attribute as described in SOAP Messages with Attachments, or via a single Text
child node containing a URI as described in the WS-I Attachments Profile 1.0 for elements of schema type ref:swaRef. These two mechanisms must be supported. The support for references via href
attribute also implies that this method should also be supported on an element that is an xop:Include element ( XOP). other reference mechanisms may be supported by individual implementations of this standard. Contact your vendor for details.

- The SOAPElement
containing the reference to an AttachmentAttachmentPart

exists or no reference can be found in this SOAPElement

Adds the given AttachmentPart
object to this SOAPMessage
object. An AttachmentPart
object must be created before it can be added to a message.

object that is to become part of this SOAPMessage
objectIllegalArgumentException
public abstract AttachmentPart createAttachmentPart()
Creates a new empty 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.

public abstract void saveChanges() throws SOAPException
Updates this SOAPMessage
object with all the changes that have been made to it. This method is called automatically when writeTo(OutputStream)
is called. 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.
SOAPException
- if there was a problem saving changes to this message.SOAPException
public abstract boolean saveRequired()
Indicates whether this SOAPMessage
object needs to have the method saveChanges
called on it.
true
if saveChanges
needs to be called; false
otherwise.public abstract void writeTo(OutputStream out) throws SOAPException, IOException
Writes this 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.
Note that this method does not write the transport-specific MIME Headers of the Message
out

object will be writtenIOException

- if there was a problem in externalizing this SOAP messagepublic void setProperty(String property, Object value) throws SOAPException
Associates the specified value with the specified property. If there was already a value associated with this property, the old value is replaced.
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.
