base64Binary by value

[Erwin Reinhoud]

Hello All,
 
I have a WSDL that defines a xs:base64Binary type. I would like to send the 
binary data by value,embedded in the SOAP XML message (Not MTOM). After 
generating the service skeleton code i can get the data by means of a 
DataHandler, which as such i implemented and deployed, however running the 
service gives a "Attachement cannot be null" Soapfault. 
 
What do i need to do (setting when generating the service skeleton?) to make 
this work service side?
 
Thanks in advance.
 
Kind regards,
 
Erwin
