But it run into compiling error. For you convenience, append the sources for mpost and context. As for metauml, have a look at this example: http://www.ntg.nl/pipermail/ntg-context/2010/049511.html

This works for me with the latest beta. For quick testing purposes just put the metauml (mp) files where your tex file is. Adam PS: The label offset problem is still present, so don't be surprised.
