I've been wondering about this exchange. I haven't looked this up, but if
this is a problem of sharing across Servlet container contexts then are you
trying "to do what ought not to be done"? Why can't you unpack Alfresco and
add in Tapestry to the existing context?
You have access to Alfresco source which might help as well.
