I just posted a HOWTO on Dynamic Proxies with RMI (=removing the need
for rmic-stubs, and how to export DP's as RMI objects) in the RMI-USERS
list:
http://archives.java.sun.com/cgi-bin/wa?A2=ind0009&L=rmi-users&D=1&O=D&P=6471
See the thread plus my updates at:
http://archives.java.sun.com/cgi-bin/wa?A1=ind0009&L=rmi-users&O=D&H=0&D=1&T=1
This could easily be used to implement a fairly lightweight and
extensible EJB container I think. Trivial even. The proxies are, as you
note, extremely reusable. See my (UPDATE) message with ReconnectProxy
and RetryProxy for example. One could imagine putting in a FailoverProxy
that switches the name that the ReconnectProxy uses to lookup the server
with.
