İf anyone can't fgure out how to read data from service;

ValueCollection params = new ValueCollection();
params.put("path", new StringPrimitive(<calledServiceInputs>));
InfoTable table = file.processServiceRequest("LoadBinary", params);
ValueCollection value = table.getFirstRow();
byte[] content = (byte[]) value.getValue(<serviceReturnValueName(example:Result>));
