Class SOAPMessage

  javax.xml.soap.SOAPMessage

public abstract class SOAPMessage

extends java.lang.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:

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

The SOAP part of a message can be retrieved by calling the method 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 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.

Constant Field Values

SOAPMessage

public SOAPMessage()

Method Detail

getContentDescription

public abstract java.lang.String getContentDescription()

Retrieves a description of this SOAPMessage object's content.

---

setContentDescription

public abstract void setContentDescription(java.lang.String description)

Sets the description of this SOAPMessage object's content with the given description.

---

getSOAPPart

public abstract SOAPPart getSOAPPart()

Gets the SOAP part of this SOAPMessage object.

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

---

removeAllAttachments

public abstract void removeAllAttachments()

Removes all AttachmentPart objects that have been added to this SOAPMessage object.

This method does not touch the SOAP part.

---

countAttachments

public abstract int countAttachments()

Gets a count of the number of attachments in this message. This count does not include the SOAP part.

---

getAttachments

public abstract java.util.Iterator getAttachments()

Retrieves all the AttachmentPart objects that are part of this SOAPMessage object.

---

getAttachments

public abstract java.util.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.

---

addAttachmentPart

public abstract void addAttachmentPart(AttachmentPart attachmentpart)

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

---

createAttachmentPart

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.

---

createAttachmentPart

public AttachmentPart createAttachmentPart(javax.activation.DataHandler datahandler)

Creates an AttachmentPart object and populates it using the given DataHandler object.

---

getMimeHeaders

public abstract MimeHeaders getMimeHeaders()

Returns all the transport-specific MIME headers for this SOAPMessage object in a transport-independent fashion.

---

createAttachmentPart

public AttachmentPart createAttachmentPart(java.lang.Object content,
                                           java.lang.String contentType)

Creates an AttachmentPart object and populates it with the specified data of the specified content type.

---

saveChanges

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 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.

---

saveRequired

public abstract boolean saveRequired()

Indicates whether this SOAPMessage object has had the method saveChanges called on it.

---

writeTo

public abstract void writeTo(java.io.OutputStream out)
                      throws SOAPException,
                             java.io.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.

---

getSOAPBody

public SOAPBody getSOAPBody()
                     throws SOAPException

Gets the SOAP Body contained in this SOAPMessage object.

---

getSOAPHeader

public SOAPHeader getSOAPHeader()
                         throws SOAPException

Gets the SOAP Header contained in this SOAPMessage object.

---

setProperty

public void setProperty(java.lang.String property,
                        java.lang.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.

---

getProperty

public java.lang.Object getProperty(java.lang.String property)
                             throws SOAPException

Retrieves value of the specified property.
