some days ago,i wrote a class to read and draw md2 file,and it works corretly
Single frame? Or did you actually get it to animate? Memories here, I too claimed that I was able to draw them, yet it took me three years before I actually had one moving

As per your question, you'll have to be more specific here. Are you talking about the half-life MDL format? If so there are a few C++ loaders available which you could attempt to translate into Java, but I tell you now that at least when I made an attempt to do so (years ago) I simply gave up because the C/C++ code was too hairy to translate, at least for me. The fact that no Java code seems to exist even today, as far as I can find with a simple Google query, at least makes me feel a little better - perhaps I wasn't too dumb to do it after all
