The EJB model for what you want to do is talked about in the
EJB spec. Essentially you write an entity bean which does
not map to a database, rather it acts as a wrapper for your
legacy application. You can think of the legacy application
as acting a bit like a database in the sense that it will
presumably be maintaining it's own data store and access
functions.
Depending on your legacy calling needs you can probably
write a bean managed persistance entity bean which has empty
load and store routines.
