I have been wondering about this:

JAVA RMI is a very good techonology, created for Distributed Systems, but why some people out there say that it is not advisable to use it over the Internet ?

How about firewalls, do they all allo you to use RMI ?

Why shouldn't I use RMI in my Distributed appl. over the Internet ? or perhaps, why should I use it ?

personally I'd say the insecure nature would be the main reason, as well as various firewall issues... you could look at combining SSL and RMI, or even Tunnelled SSL and RMI might work... I've never had to work on clients outside corporate LAN (with RMI that is...)

Cheers,

Security, overhead, possible overkill.  Most people find that they can simply implement a system where the different components simply send short messages (often in xml) rather than the more complicated rmi.  


but anyways

You can set a security manager for RMI to solve most security issues (limiting to certain clients, JVM restrictions, signed code only, directory restrictions, etc.).  But, RMI is usually overkill, and using some messaging is often preferable to having an application execute remote code directly.

the lack of security I was describing was mainly in the plain text nature...
but, yes, the messaging mechanism does sound like a better approach - RMI will presumably keep sockets, etc, for the lifetime of the connect, etc.

probably the easiest would be to use JSP webpage, and use a <form> to POST the chat lines - refreshing the client side periodically - this way means that no client specific code is required, just a web-browser...
