[Khan Navaz]

*BeanShell:*
String file =
Path+"/data/abcService/common/deep_foldered_images_in_zip.zip";
byte[] byteArray;
byte[] byteString;

 try {
    byteArray = IOUtils.toByteArray(new FileInputStream(file));
      } catch (IOException e){
    e.printStackTrace();
 }

vars.putObject("byteString",byteArray);

*SOAP Request:*
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
