problem with syncronous messages and attachments
I have a simple axis service with an operation with the following
definition:
public OMElement queryStatisticsReturn(OMElement element)
{
try
{
return super.processAxisService(element);
} catch (Exception ex)
{
InitializationServlet.error("", ex);
return null;
}
}
My service extends a class called PreprocessSoap that contains
processAxisService. processAxisService does some preprocessing, calls an
abstract method called processBody that gets executed in my service
class, and does some post processing. I am able to get the xml
processing to work just fine but I can't get the attachments to work. I
have the following attachment processing logic inside processAxisService:
MessageContext mc =
MessageContext.getCurrentMessageContext().getOperationContext().getMessageContext(WSDLConstants.MESSAGE_LABEL_OUT_VALUE);
if (this.attachmentContent != null)
{
for (int i = 0; i < this.attachmentContent.length; i++)
{
DataSource ds = new
ByteArrayDataSource(this.attachmentContent[i].toByteArray(),
this.attachmentContentType[i]);
DataHandler dh = new DataHandler(ds);
mc.addAttachment(dh);
}
}
mc.setSoapAction(bodyElement.getLocalName());
mc.setDoingSwA(true);
mc.setFLOW(MessageContext.OUT_FLOW);
All this seems to work fine until I check the response on the client
side with the following bit of code:
response.getEnvelope().getBody().getFirstElement().serialize(System.out);
System.out.println("\n\n# of attachments: " +
response.getOperationContext().
getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE).getAttachmentMap().
getAllContentIDs().length);
System.out.println("soap action: " +
response.getOperationContext().
getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE).getSoapAction());
There was a soap action and an attachment in the sent message but it is
not in the received message. I am guessing this is because I changed the
wrong message context. How do I get access to the right message context,
i.e. the message context that actually gets returned to the client?

This is actually a fairly pressing issue. I would appreciate any help I
can get.
Thanks,
