AttachmentPart
class. If you need to include an attachment with the SOAP message, call one of
SOAPMessage
's
createAttachmentPart()
methods to create and return an
AttachmentPart
object.Afterconfiguringthisobject,call
SOAPMessage
's
void
addAttachmentPart(AttachmentPart attachmentPart)
method to add
the given
attachmentPart
-referenced object to this
SOAPMessage
object.
To send the SOAP message and receive a reply, invoke
SOAPConnection
's
SOAPMessage call(SOAPMessage request, Object to)
method. The
specified request message is sent to the endpoint identified by
to
, which may be
a
String
or
URL
instance. This method throws
SOAPException
when a SOAP
problem occurs, and blocks until it receives a SOAP message, which it returns as a
SOAPMessage
object. The following example provides a demonstration:
String endpoint = "http://tutortutor.ca/library/gettitle";
// Send the request message identified by soapm to the web
service at the specified
// endpoint and return the response message.
SOAPMessage response = soapc.call(soapm, endpoint);
Alternatively, you can call
SOAPConnection
's
SOAPMessage get(Object
to)
methodtorequestaSOAPmessage.Aswith
call()
,
get()
blocksuntilthere
is a reply, and throws
SOAPException
when a SOAP problem occurs.
Afterfinishingyour
call()
and/or
get()
invocations,call
SOAPConnection
's
void close()
method to close the connection to the endpoint. If this method has
already been called, a subsequent attempt to close the connection results in a thrown
SOAPException
instance.
