Re: [RMI] Questions about RMI and Tomcat/Apache

Thanks for your quick response, I'm quite sure that I'm not completely
grasping all of this, I'm not even sure what questions to ask. 

What I need is to be able to send and receive Java objects from the
client (application and applet) to the server. If possible my RMI server
needs to be setup so this data is passed by way of the HTTP protocol on
port 80. I need this because of the way the server is setup on the
network (the server is in the internal network and traffic is routed to
it, through the firewall, by way of a HTTP reverse proxy from a separate
system in the DMZ).

It sounds like what you're saying below is that even if I create this
server from a servlet in tomcat I'm still not accessing that server
through Tomcat, is that correct? 

Is something like the following even possible within the client where it
references a webserver directly? 

  MyServer obj  =
(SomeObject)Naming.lookup("http://myhost.com/MyServer");

I may be confused here, I was reading about the java.rmi.server.codebase
system property which can be set to a http address. I'm thinking now
that this is more like the classpath then the location of the RMI
server. Correct?

Thanks again for your comments,

David

I think the question is somewhat strangely asked. Technically speaking
there 
is no "RMI Server". That is typically something you create. Secondly,
Apache 
Webserver is a native application and unless mod_java is installed, does
not 
run Java applications. 
Tomcat is among other things a servlet container, so you can stick your
RMI 
stuff into a servlet and deploy it via a WAR, if the WebApp has enough 
permissions to do network operations and much more. The RMI Registry can
be 
run inside the same servlet by checking and creating it thru the 
LocateRegistry class.
