You have several options:

• mtom specification, supported e.g. in jaxb, looks like in spring-ws as well: Stream MTOM Web Services in Spring Web Services Framework

• there are special data types in xml-schema to handle with binary data, see: JAXB (un)marshalling of xsd types: xsd:base64Binary and xsd:hexBinary

• finally you can serialize this data yourself to text format (e.g. using base64) and pass as part of the request using simple xsd:string type
