public static Message create(BindingContext context, Object jaxbObject, SOAPVersion soapVersion, MessageHeaders headers, AttachmentSet attachments) -
create
Creates aMessage
backed by a JAXB bean.- Parameters:
context
- The JAXBContext to be used for marshalling.jaxbObject
- The JAXB object that represents the payload. must not be null. This object must be bound to an element (which means it either is aJAXBElement
or an instanceof a class withXmlRootElement
).soapVersion
- The SOAP version of the message. Must not be null.
-

@Deprecated public static Message create(jakarta.xml.bind.JAXBContext context, Object jaxbObject, SOAPVersion soapVersion) Deprecated. -
createRaw
@Deprecated public static Message createRaw(jakarta.xml.bind.JAXBContext context, Object jaxbObject, SOAPVersion soapVersion) Deprecated.For use when creating a Dispatch object with an unknown JAXB implementation for he JAXBContext parameter. -
create
Creates aMessage
backed by a JAXB bean.- Parameters:
bridge
- Specify the payload tag name and howjaxbObject
is bound.
-
hasHeaders
public boolean hasHeaders()Description copied from class:Message
Returns true if headers are present in the message.- Specified by:
hasHeaders
in classMessage
- Returns:
- true if headers are present.
-
getHeaders
Description copied from class:Message
Gets all the headers of this message.Implementation Note
Message
implementation is allowed to defer the construction ofMessageHeaders
object. So if you only want to check for the existence of any header element, useMessage.hasHeaders()
.- Specified by:
getHeaders
in classMessage
- Returns:
- always return the same non-null object.
-
getPayloadLocalPart
Description copied from class:Message
Gets the local name of the payload element.- Specified by:
getPayloadLocalPart
in classMessage
- Returns:
- null if a
Message
doesn't have any payload.
-
getPayloadNamespaceURI
Description copied from class:Message
Gets the namespace URI of the payload element.- Specified by:
getPayloadNamespaceURI
in classMessage
- Returns:
- null if a
Message
doesn't have any payload.
-
hasPayload
public boolean hasPayload()Description copied from class:Message
Returns true if aMessage
has a payload.A message without a payload is a SOAP message that looks like:
<S:Envelope> <S:Header> ... </S:Header> <S:Body /> </S:Envelope>
- Specified by:
hasPayload
in classMessage
-
readPayloadAsSource
Description copied from class:Message
Returns the payload as aSource
object. This consumes the message.- Specified by:
readPayloadAsSource
in classMessage
- Returns:
- if there's no payload, this method returns null.
-
readPayloadAsJAXB
public <T> T readPayloadAsJAXB(jakarta.xml.bind.Unmarshaller unmarshaller) throws jakarta.xml.bind.JAXBException Description copied from class:Message
Reads the payload as a JAXB object by using the given unmarshaller. This consumes the message.- Overrides:
readPayloadAsJAXB
in classAbstractMessageImpl
- Throws:
jakarta.xml.bind.JAXBException
- If JAXB reports an error during the processing.
-
readPayload
Description copied from class:Message
Reads the payload as aXMLStreamReader
This consumes the message. The caller is encouraged to callXMLStreamReaderFactory.recycle(XMLStreamReader)
when finished using the instance.- Specified by:
readPayload
in interfaceStreamingSOAP
- Specified by:
readPayload
in classMessage
- Returns:
- If there's no payload, this method returns null.
Otherwise always non-null valid
XMLStreamReader
that points to the payload tag name. - Throws:
XMLStreamException
-
writePayloadTo
protected void writePayloadTo(ContentHandler contentHandler, ErrorHandler errorHandler, boolean fragment) throws SAXException Writes the payload as SAX events.- Specified by:
writePayloadTo
in classAbstractMessageImpl
fragment
- if true, this method will fire SAX events without start/endDocument events, suitable for embedding this into a bigger SAX event sequence. if false, this method generaets a completely SAX event sequence on its own.- Throws:
SAXException
-
writePayloadTo
Description copied from class:Message
Writes the payload to StAX. This method writes just the payload of the message to the writer. This consumes the message. The implementation will not writeXMLStreamWriter.writeStartDocument()
norXMLStreamWriter.writeEndDocument()
If there's no payload, this method is no-op.
- Specified by:
writePayloadTo
in interfaceStreamingSOAP
- Specified by:
writePayloadTo
in classMessage
- Throws:
XMLStreamException
- If theXMLStreamWriter
reports an error, or some other errors happen during the processing.
-
copy
Description copied from class:Message
Creates a copy of aMessage
.This method creates a new
Message
whose header/payload/attachments/properties are identical to thisMessage
. Once created, the createdMessage
and the originalMessage
behaves independently --- adding header/ attachment to oneMessage
doesn't affect anotherMessage
at all.This method does NOT consume a message.
To enable efficient copy operations, there's a few restrictions on how copied message can be used.
- The original and the copy may not be
used concurrently by two threads (this allows two
Message
s to share some internal resources, such as JAXB marshallers.) Note that it's OK for the original and the copy to be processed by two threads, as long as they are not concurrent. - The copy has the same 'life scope'
as the original (this allows shallower copy, such as
JAXB beans wrapped in
JAXBMessage
.)
A 'life scope' of a message created during a message processing in a pipeline is until a pipeline processes the next message. A message cannot be kept beyond its life scope. (This experimental design is to allow message objects to be reused --- feedback appreciated.)
Design Rationale
Since a
Message
body is read-once, sometimes (such as when you do fail-over, or WS-RM) you need to create an identical copy of aMessage
.The actual copy operation depends on the layout of the data in memory, hence it's best to be done by the
Message
implementation itself.The restrictions placed on the use of copied
Message
can be relaxed if necessary, but it will make the copy method more expensive.IMPORTANT
WHEN YOU IMPLEMENT OR CHANGE A
#copy()
METHOD, YOU MUST USE THEMessage.copyFrom(com.sun.xml.ws.api.message.Message)
METHOD IN THE IMPLEMENTATION. - The original and the copy may not be
used concurrently by two threads (this allows two
