[MTOM] InstantiationException

[Julien HENRY]

Hi,

I'm a newbie with Webservices, and I have to write a simple one that provide an 
image to the client. I want to use MTOM, and I tried to use mtom sample in Axis 
2.1.1 distribution.

I get the following exception when trying to retrieve the image:

org.apache.axis2.AxisFault: javax.activation.DataHandler; nested exception is: 
    java.lang.InstantiationException: javax.activation.DataHandler

I think the server is working fine, because tcpmon trace looks good:
