You may be able to do so with just the java.security package.

From
http://java.sun.com/j2se/1.4.2/docs/api/java/security/MessageDigest.html
where you see

MessageDigest md = MessageDigest.getInstance("SHA"); // <-- replace the SHA
with MD5, and try it out

try {
md.update(toChapter1);
MessageDigest tc1 = md.clone();
byte[] toChapter1Digest = tc1.digest();
md.update(toChapter2);
...etc.
} catch (CloneNotSupportedException cnse) {
throw new DigestException("couldn't make digest of partial content");
}


HTH,
