I use IBM MQSeries to transfer a BytesMessage that contains a bunch of text and binary files. I have an integer representing total number of files, then for each file I write an integer of its size before its byte array(contains the file). So on the receiver side the onMessage() can easily read and write them according to their sizes. I tested on NT and every file gets transferred to a new directory without any change. My question is: if I transfer these files to a UNIX machine, how would the message behave because of the Big-little endian thing? Thanks.
