In the server side i got the code using code generation tools, but the dataHandler is null. And the code like this:

 public void publishEvent
              (
              ch.iec.www.tc57._2008.schema.message.EventMessage eventMessage
              )
        throws FaultMessage{
            //TODO : fill this with the necessary business logic

                EventMessageType emt = eventMessage.getEventMessage();

                 PayloadType plt = emt.getPayload();

                 DataHandler dataHandler =  plt.getPayloadTypeChoice_type0().getCompressed();




                 if(dataHandler!=null){....}
              }

I fixed it.

It's about my XSD

       <xs:choice>
            <xs:any namespace="##other" processContents="skip" minOccurs="0" maxOccurs="unbounded">
                <xs:annotation>
                    <xs:documentation>For XML payloads</xs:documentation>
                </xs:annotation>
            </xs:any>
            <xs:element name="Compressed" type="xs:string" minOccurs="0">
                <xs:annotation>
                    <xs:documentation>For compressed and/or binary, uuencoded payloads</xs:documentation>
                </xs:annotation>
            </xs:element>
        </xs:choice>

When i delete the <xs:choice> portion of the XSD, i can get the dataHandler. not supported?
