Hi Michael, I implemented your code (i needed md5 anyway...): works fine on both gaej sdk and on live gaej too. And it's normal because java.security.MessageDigest is on the GAEJ JRE Class white list: see http://code.google.com/appengine/docs/java/jrewhitelist.html)
Your issue: I would guess that your "Referenced libraries" as initially set by the SDK have changed and are now wrong: can you list us in details us what you have in there ? regards didier On Jun 11, 3:14 pm, Jake <[email protected]> wrote: > Hey, > > Nothing additional on the build path.
