Adding attachments on xsd:hexBinary gives unmarshalling error.

Hi folks,

I tried using open source Soap UI to send attachments.

My xsd is defined as follows    <element name = "attachment" type="xsd:hexBinary" xmlns:xsd="http://www.w3.org/2001/XMLSchema"/ >.

My requirement is to send attachment using MTOM. For that I set mtom = true in request properties and used mtompolicy to force all requests to MTOM. I get the following error for attachments in hexBinary.

Unmarshalling Error: java.lang.IllegalArgumentException: contains illegal character for hexBinary: PCFET0NUWVBFIGh0bWwgUFVCT ..... I used cxf 3.1.6 stack to create request service. 

Thanks,
