What you do is you implement proxy class on the client which you call to do
any action again s beans. The proxy then sends your call as a request to the
servlet and then one servlet receives the call, the executes it and return
back and your proxy class which decodes it from HTTP, converts it to
expected data type and return it back to client without client knowing that
there was HTTP call executed.

the prolem is, that this is only for RMI, but what about the JNDI lookups of
the beans from a client?
are there any extensions for Jonas that implement the communication
interfaces in order to deal with all this HTTP tunelling?

Hi Markus,
I think you will need to resolve the communication yourself by putting HTTP
server (e.g. Jetty from www.mortbay.com) with servlet behind you destination
firewall. How to communicate is described in
http://developer.java.sun.com/developer/technicalArticles/RMI/rmi/

the architecture is:
starting from the client:
1) Java client Application
2) firewall that only allow traffic through port 80 ( I have no control over
this firewall, this is a firewall somewhere in the internet.
3) internet
4) "my firewall", I have control of.
5) Jonas server
hope that gives you an idea
thanks markus

Hi,
I am not familiar with your architecture and limitations but, can't you put
your servlet engine/webserver behind the firewall as well?

thanks for that info, but that was not quite what I wanted to know...
what, if i have a Java client connected to the Jonas server that is behind
its own firewall that only allows traffic through port 80 (probably only
HTTP traffic..)?
is there a way of looking up the beans via HTTP tunneling or similar and
connecting to a servlet or similar that forwards the client requests ?
if jonas does not support that, do other ejb vendors support that?
thanks for any hints.
markus
