Thank you !!!
using LABEL_IN_VALUE is coreect !!
Then in my client file, I only have to perform the following code and
the image is created on my hard disk !
OMElement xop = (OMElement)imageEl.getFirstOMChild();
OMAttribute attr = xop.getAttribute(new QName("href"));
String contentID = attr.getAttributeValue();
Attachments attachment = (Attachments)
msgcts.getProperty(MTOMConstants.ATTACHMENTS);
contentID = contentID.trim();
if (contentID.substring(0, 3).equalsIgnoreCase("cid")) {
contentID = contentID.substring(4);
}
DataHandler dataHandler =
attachment.getDataHandler(contentID);
Image image = new
ImageIO().loadImage(dataHandler.getDataSource().getInputStream());
FileOutputStream imageOutStream = new
FileOutputStream("/home/souillac/thinkAttachment.jpg");
new ImageIO().saveImage("image/jpeg", image,
imageOutStream);
Thanks again,
Regards,
Charles

Hi,
I can suggested three ways to access the binary content according to
my choice priority.
1. I don't have a much of a knowledge in Data Bounded code. But if the
data binding is properly handled for MTOM then there should be a
getter for a Data Handler or a Byte[] in your
helloworld.InitiateHelloWorldDocument ..
2. Regarding your server code,
You can access the OMText object containing the Binary data from
imageEle element by calling it's getFirstChild() method. Then you can
call the getDataHandler() method of that OMText instance to get the
DataHandler. This should work.
3.I don't understand why you are trying to access the attachments Map
in the msgContext. This method is to use with SwA type attachments,
though it should work even in this scenario(with loads of unnecessary
overhead) . I noticed that you are setting the out message context in
the setOperationContext method using
WSDLConstants.MESSAGE_LABEL_OUT_VALUE. Try using LABEL_IN_VALUE.
I personally don't recommend the 3rd method to access MTOM
attachments. It's lot easier than that. :)
