To provide a bit more information we are used complex types containing base64Binary encoded data, for example <s:element name="StoreAsset"> | <s:complexType> | <s:sequence> | <s:element minOccurs="1" maxOccurs="1" name="sessionId" type="s:string"/> | <s:element minOccurs="0" maxOccurs="1" name="assetRef" type="s:string"/> | <s:element minOccurs="0" maxOccurs="1" name="nodeRef" type="s:string"/> | <s:element minOccurs="0" maxOccurs="1" name="leafName" type="s:string"/> | <s:element minOccurs="0" maxOccurs="unbounded" name="values" type="tns:NameTypeValue"/> | <s:element minOccurs="1" maxOccurs="1" name="asset" type="s:base64Binary"/> | </s:sequence> | </s:complexType> | </s:element> | The generated interface is /** | * | * @param asset | * @param values | * @param assetRef | * @param leafName | * @param sessionId | * @param nodeRef | * @throws SessionExpiredException | * @throws NsteinDPSErrorException | */ | @WebMethod(operationName = "StoreAsset", action = "StoreAsset") | @RequestWrapper(localName = "StoreAsset", targetNamespace = "http://services.nstein.com/NsteinDPS", className = "com.nstein.services.nsteindps.StoreAsset") | @ResponseWrapper(localName = "StoreAssetResponse", targetNamespace = "http://services.nstein.com/NsteinDPS", className = "com.nstein.services.nsteindps.StoreAssetResponse") | public void storeAsset( | @WebParam(name = "sessionId", targetNamespace = "http://services.nstein.com/NsteinDPS") | String sessionId, | @WebParam(name = "assetRef", targetNamespace = "http://services.nstein.com/NsteinDPS", mode = WebParam.Mode.INOUT) | Holder<String> assetRef, | @WebParam(name = "nodeRef", targetNamespace = "http://services.nstein.com/NsteinDPS") | String nodeRef, | @WebParam(name = "leafName", targetNamespace = "http://services.nstein.com/NsteinDPS") | String leafName, | @WebParam(name = "values", targetNamespace = "http://services.nstein.com/NsteinDPS") | List<NameTypeValue> values, | @WebParam(name = "asset", targetNamespace = "http://services.nstein.com/NsteinDPS") | byte[] asset) | throws NsteinDPSErrorException, SessionExpiredException | ; | I believe that byte[] asset needs to be changed to DataHandler asset but doing this alone doesn't seem to work. Any pointers as to what else is required or link to an example would be very helpful.
