In addition to Avalon, you might look at HP's Common Services Framework
(underlying their HP-Internet Server and HP-Application Server) or the
Enhydra Services Architectures underlying the Lutris Enhydra App Server.
Both these frameworks are being considered as APIs or concept-sources
for the JSR-111 work and might be very useful to someone doing a mixture
of J2EE and custom-components (services). Of course, until/unless
JSR-111 (or JSR-159, which is probably better for this purpose because
it's J2EE-specific) blesses a standard, any work you do in this way is
subject to some level of vendor lock-in...
