It is written

byte[][] getImagesForFields(java.lang.String[] fieldnames) 

Gets an array of images for the given fields.

On the other hand, as long as I use the method in the web application project built on asp.net 2.o using c#;

the provided web method declared above, returns sbyte; Have a look my code below;

  formClearanceService.openSession(imageServiceUser);
  formClearanceService.prepareInstance(formId);
  byte[][] fieldImagesList = formClearanceService.getImagesForFields(fieldNames);
  formClearanceService.closeSession();

thus I get the following error: Cannot implicitly convert type 'sbyte[]' to 'byte[][]'

So now, 1- should I ask the web service provider what is going on? or 2- any other way that can use the sbyte as I was suppose to use byte[][] like following using: byte[] ssss = fieldImagesList [0]..
