I thought I was having a similar problem to Jeremy. In the end I found that it was my own fault. I had packaged my ejb-xml file in 'meta-inf' folder (lower case). I tried using upper case, 'META-INF', and it worked fine. It's quite a novice mistake to make but sure I'm not the only one who has made it so hopefully this post will benefit someone else.
