a) Is the server that you will call a web service able to receive SOAP
attachments? (MTOM) I am assuming it is.
b) If you use Axis2, your web services client is already able to RETRIEVE
attachments. The generated code will look like
TheResponse response =
yourService.serviceWithAttachments(parameter1, parameter2, parameter3)
InputStream is =
response.getDataHandler().getInputStream();
...here use the input stream to read the attachment ...
c) If you use Axis2 and you want to SEND attachments, you need to enable the
client code
YourServiceStub stub = new YourServiceStub("http://your.url/";);
Options options = stub._getServiceClient().getOptions();
options.setProperty( Constants.Configuration.ENABLE_MTOM,
Constants.VALUE_TRUE);
and then you will need to implement a DataSource and set it in your request
object.
Since you want to just forward the request, you may want to use
PipedInputStream/PipedOutputStream in your DataSource implementation
