How about using a method like this?

There is such a method in the java.util.Arrays class - its called 'equals' and takes the 2 byte arrays to be compared as arguments. The following is pasted straight from the API documentation:
equals
public static boolean equals(byte[] a,
byte[] a2)
Returns true if the two specified arrays of bytes are equal to one another. Two arrays are considered equal if both arrays contain the same number of elements, and all corresponding pairs of elements in the two arrays are equal. In other words, two arrays are equal if they contain the same elements in the same order. Also, two array references are considered equal if both are null.
Parameters:
a - one array to be tested for equality.
a2 - the other array to be tested for equality.
Returns:
true if the two arrays are equal.
Hope this helps
Michael
