app client jndi
I'm not 100% sure I understand the current app client jndi handling,
but my impression is that jndi lookup pulls the read only context back
from the server.
Is there some reason the read-only-context is not packed into the app
client configuration so that no lookup communication to the server is
needed? I would expect this to be simpler and faster. It also would
not have introduced bugs in the non-app client jndi.
Please explain.
thanks

Actually this is way simpler. In one fell swoop we connect to the
server and pull down the JNDI context and all proxies in the tree write
replaced in the object output stream to be connected to the current
server. This has a lot of nice side effects. First is it is really
fast as we only have a single communication with the server at startup
for all JNDI lookups. Also, we don't have to have special code on the
client side to have the initially disconnected proxy find the server.
We can reuse all enc creation code in the deployment code without any
change. We can support lookup of objects that are not EJBs (the
current JNDI code only supports EJBs).
Now I'm not 100% sure that we won't need special code on the client and
special enc creation code, but this solution is simple and should
work.

That is because I made David check it in before he was ready, so I
could begin working with the app client side. He is fixing the bug.
