How can I use MD5 digest in Java?

Question

Hello mates,
I tried to use MessageDigest class to do a md5 digest to a String:
MessageDigest md = MessageDigest.getInstance("MD5");
byte toChapter1;
byte toChapter2;
try {
     md.update(toChapter1);
     MessageDigest tc1 = md.clone();
     byte[] toChapter1Digest = tc1.digest();
     md.update(toChapter2);
} catch (CloneNotSupportedException cnse) {
     throw new DigestException("couldn't make digest of partial content");
}But its not working. I dnt know why..
REGARDS,
Elton

You don't say what it does not do that is should or what it should do that it does not! Also, I don't understand why you are cloning the MessageDigest object!
