Re:  replacing of characters based on position
well, Its part of the requirement where i have replace 0 in place of '-', so
that when we get this uuid back, we will replace '0' with '-'. 
         The
reason of this mq is replacing - with 0 because - is not a right hexadecimal
value. before droping this uuid in mq, i want to replace it with 0 then once i
get the response from mq i want to replace 0 with - so that i will make sure
that uniqueness of uuid.
