Re: RMI and Threading
I have a task for a class i am in to write an instant messaging java
app that communicates with a server using RMI. The client has to have
two threads running, one to send out messages (communicate with server
to get information about the other client to send to and then open a
socket to that client's address) and another to listen for messages (a
serversocket accepting incoming messages from other clients).
I have used threads before but usually to allow concurrent connections
on a server and for some reason this is really messing me up.
Any advice on how to get my mind around this would be appreciated....
I know this is kind of vague but I am not exactly sure what else to
Thanks for any direction....
Generally, the RMI framework handles the threading and connections for
you. On the other hand, RMI is particular poorly suited to any
situation where one or both sides are behind a firewall. You'd be better
off finding an alternate means of communication. Either by designed a
custom protocol yourself, suited specifically to your Instant Messaging
domain, or by using one of the many technologies designed for this use.
Also note that there are some libraries that handle I.M. with all the
major networks for you. Libpurple comes to mind, but its not Java
based, so you'd have to either find a Java version, write a JNI wrapper,
or create your app in another language.
