use a CRC (Checksum algorithm)...
you can generate one by converting all fields to stringized version of them;
then concatenating them, then using that value to create the hash.
java.util.zip has a couple of classes (Adler32 and CRC32 come to mind) that
will calculate it for you.

Subject: hashCode for entity bean with multiple pk columns
Anyone have suggestion regarding standard way to write int hashCode() method
now required in PK when one has multiple PK's.
If I have one PK value (Integer myInteger) I do this:
public int hashCode() {
return myInteger.hashCode();
}
How about if I have two Ingegers and a Timestamp making up my PK, what is a
nice simple clean way to write hashCode method?
