Need Help in passing a string as a attachment

[Tony Evans]

I am trying to pass a string as a attachment, but when I examine what is being sent it looks as if the string is being passed in the Body.

According to weblogic :
Certain Java data types, if used as parameters or return values of a method that implements a Web Service operation, are automatically transported as SOAP Attachments (rather than elements in the SOAP body) when going over the wire.

As I understand it this means passing a parameter as a datahandler.

Here is my code snippet

String attachement = attach.getAttachments().toString();
StringDataSource sds = new StringDataSource(attachement,"String","Attachment");

DataHandler dh = new DataHandler(sds);
Results res = new Results();

//The remote soap call.
port.scanForViruses(dh);

I have created a DataHandler and am passing it as a parameter, as laid down in weblogic.

I have set up a sniffer, but not sure what I should be looking for to say it has been passed as a Attachement:
Here is the sniffer output:
