Not so. Downloaded the second edition from theserverside a couple of weeks ago and just checked. It's still there. Got to this link and click on the whole book link for the 2nd Edition. On the subsequent page click on the "Mastering EJB 2nd Edition PDF" link. You'll then be prompted to login to theserverside and once you have, you'll be redirected to a page displaying the 2nd edition PDF. From there, just save it.
Tested it out just be fore this reply.
You showed up just in time for the waffles! And this tiny ad:
