A developer is building a JAX-WS Web service to be deployed on IBM Web Sphere Application Server V7.0. The service consumers are financial institutions with client applications using Microsoft .NET V3.5. The service will be used to retrieve image files and send them to the financial institutions. What is the recommended approach to send the image files?

  1. SOAP with Attachments

  2. Direct Internet Message Encapsulation (DIME)

A developer is creating a JAX-WS Web service. The Web service will be used to sendcheque image file from the provider to the requestor. Given the following extract:

@MTOM(enabled=true, threshold=50)

@Web Service(name=quot;Image Servicequot;,

target Namespace=quot;http://com.test.ImageServicequot;) public class Image Provider {

What does the threshold parameter indicate?

  1. The minimum number of attachments that can be sent in the message

  2. The maximum number of attachments that can be sent in the message

  3. The maximum size in bytes for each attachment to be sent using MTOM.

  4. The minimum size in bytes for each attachment before MTOM is used. Smaller attachments will use base64 inline encoding.

  5. The maximum size in bytes for each attachment before MTOM streams to disk. Smaller

attachments will keep the attachment in-memory.
