All Implemented Interfaces:

java.io.Serializable

public class Message

extends SOAPMessage

implements java.io.Serializable

A complete SOAP (and/or XML-RPC, eventually) message. Includes both the root part (as a SOAPPart), and zero or more MIME attachments (as AttachmentParts).

Eventually should be refactored to generalize SOAPPart for multiple protocols (XML-RPC?).

Constructor Detail

Message

public Message(java.lang.Object initialContents,
               boolean bodyInStream)

Construct a Message, using the provided initialContents as the contents of the Message's SOAPPart.

Eventually, genericize this to return the RootPart instead, which will have some kind of EnvelopeFactory to enable support for things other than SOAP. But that all will come later, with lots of additional refactoring.

Parameters:

initialContents - may be String, byte[], InputStream, SOAPEnvelope, or AxisFault.

bodyInStream - is true if initialContents is an InputStream containing just the SOAP body (no SOAP-ENV).

Message

public Message(java.lang.Object initialContents,
               boolean bodyInStream,
               MimeHeaders headers)

Construct a Message, using the provided initialContents as the contents of the Message's SOAPPart.

Eventually, genericize this to return the RootPart instead, which will have some kind of EnvelopeFactory to enable support for things other than SOAP. But that all will come later, with lots of additional refactoring.

Parameters:

initialContents - may be String, byte[], InputStream, SOAPEnvelope, or AxisFault.

bodyInStream - is true if initialContents is an InputStream containing just the SOAP body (no SOAP-ENV).

headers - Mime Headers.

Message

public Message(java.lang.Object initialContents,
               MimeHeaders headers)

Construct a Message, using the provided initialContents as the contents of the Message's SOAPPart.

Eventually, genericize this to return the RootPart instead, which will have some kind of EnvelopeFactory to enable support for things other than SOAP. But that all will come later, with lots of additional refactoring.

Parameters:

initialContents - may be String, byte[], InputStream, SOAPEnvelope, or AxisFault.

headers - Mime Headers.

Message

public Message(java.lang.Object initialContents,
               boolean bodyInStream,
               java.lang.String contentType,
               java.lang.String contentLocation)

Construct a Message, using the provided initialContents as the contents of the Message's SOAPPart.

Eventually, genericize this to return the RootPart instead, which will have some kind of EnvelopeFactory to enable support for things other than SOAP. But that all will come later, with lots of additional refactoring.

Parameters:

initialContents - may be String, byte[], InputStream, SOAPEnvelope, or AxisFault.

bodyInStream - is true if initialContents is an InputStream containing just the SOAP body (no SOAP-ENV).

contentType - this if the contentType has been already determined. (as in the case of servlets);

Message

public Message(java.lang.Object initialContents)

Construct a Message. An overload of Message(Object, boolean), defaulting bodyInStream to false.

Method Detail

getAttachmentImplClassName

public static java.lang.String getAttachmentImplClassName()

Returns name of the class prividing Attachment Implementation

Returns:

class Name

getMessageType

public java.lang.String getMessageType()

setMessageType

public void setMessageType(java.lang.String messageType)

getMessageContext

public MessageContext getMessageContext()

setMessageContext

public void setMessageContext(MessageContext msgContext)

getSOAPPart

public SOAPPart getSOAPPart()

Get this message's SOAPPart.

Eventually, this should be generalized beyond just SOAP, but it's hard to know how to do that without necessitating a lot of casts in client code. Refactoring keeps getting easier anyhow.

Specified by:

getSOAPPart in class SOAPMessage

Returns:

the SOAPPart object for this SOAPMessage object

getSOAPPartAsString

public java.lang.String getSOAPPartAsString()
                                     throws AxisFault

AxisFault

getSOAPPartAsBytes

public byte[] getSOAPPartAsBytes()
                          throws AxisFault

AxisFault

getSOAPEnvelope

public SOAPEnvelope getSOAPEnvelope()
                             throws AxisFault

Get this message's SOAPPart as a SOAPEnvelope

AxisFault

getAttachmentsImpl

public Attachments getAttachmentsImpl()

Get the Attachments of this Message. If this returns null, then NO ATTACHMENT SUPPORT EXISTS in this configuration of Axis, and no attachment operations may be performed.

getContentType

public java.lang.String getContentType(SOAPConstants sc)
                                throws AxisFault

AxisFault

getContentLength

public long getContentLength()
                      throws AxisFault

AxisFault

writeTo

public void writeTo(java.io.OutputStream os)
             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.

Specified by:

writeTo in class SOAPMessage

Parameters:

os - the OutputStream object to which this SOAPMessage object will be written

Throws:

SOAPException - if there was a problem in externalizing this SOAP message

java.io.IOException - if an I/O error occurs

getContentDescription

public java.lang.String getContentDescription()

Retrieves a description of this SOAPMessage object's content.

Specified by:

getContentDescription in class SOAPMessage

Returns:

a String describing the content of this message or null if no description has been set

See Also:

setContentDescription(java.lang.String)

setContentDescription

public void setContentDescription(java.lang.String description)

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

Specified by:

setContentDescription in class SOAPMessage

Parameters:

description - a String describing the content of this message

See Also:

getContentDescription()

saveChanges

public 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.

Specified by:

saveChanges in class SOAPMessage

Throws:

SOAPException - if there was a problem saving changes to this message.

saveRequired

public boolean saveRequired()

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

Specified by:

saveRequired in class SOAPMessage

Returns:

true if saveChanges has been called on this message at least once; false otherwise.

getMimeHeaders

public MimeHeaders getMimeHeaders()

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

Specified by:

getMimeHeaders in class SOAPMessage

Returns:

a MimeHeaders object containing the MimeHeader objects

removeAllAttachments

public void removeAllAttachments()

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

This method does not touch the SOAP part.

Specified by:

removeAllAttachments in class SOAPMessage

countAttachments

public int countAttachments()

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

Specified by:

countAttachments in class SOAPMessage

Returns:

the number of AttachmentPart objects that are part of this SOAPMessage object

getAttachments

public java.util.Iterator getAttachments()

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

Specified by:

getAttachments in class SOAPMessage

Returns:

an iterator over all the attachments in this message

getAttachments

public 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.

Specified by:

getAttachments in class SOAPMessage

Parameters:

headers - a MimeHeaders object containing the MIME headers for which to search

Returns:

an iterator over all attachments that have a header that matches one of the given headers

addAttachmentPart

public 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.

Specified by:

addAttachmentPart in class SOAPMessage

Parameters:

attachmentpart - an AttachmentPart object that is to become part of this SOAPMessage object

Throws:

java.lang.IllegalArgumentException

createAttachmentPart

public 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.

Specified by:

createAttachmentPart in class SOAPMessage

Returns:

a new AttachmentPart object that can be populated and added to this SOAPMessage object
