I am not an expert in RMI, so not sure, how significant codebase and security for this exam.
Please comment on my approach. 1. I am planning to include the stubs with the client. 2. I am not planning to suggest the usage of codebase. 3. I will use a policy file, does this mean that I must intialize security manager too ?. Please help me get educated. Thanks, -Rajesh
Without a security manager, a policy file doesn't do anything. You do not need an RMISecurityManager, the bog standard SecurityManager is enough. In fact you do not strictly need security at all, although I would recommend it certainly on the server side. - Peter

Peter, Thanks for the information. How about code base ?. I finished the assignment very quickly and just class documentation took lots of time, now these minor issues are killing me. Thanks again, -Rajesh
If you want to use the java.rmi.server.codebase property during the server startup, you need to use absolute URL which is not possible for my implementation since I didn't use a HTTP server or didn't want to hardcode the drive letter. Also the codebase property really matters only when the rmiregistry tries to instantiate the _Stub instance. Take a look at the thread for my explanation.
I wish I had the link, but yesterday Peter said that we don't need the security manager on either side, since we are not downloading the stubs dynamically. I myself put a SercurityManager only on the client. I could never get it to work on the server. I have a policy file, but it gives all access, so if there was no SecurityManager on the client, I wouldn't have needed it at all. I did not have a policy file for the server Mark
Sheesh you walk away for a 30 minute meeting and everyone posts before you. What they just said. [ April 16, 2002: Message edited by: Mark Spritzler ]
Ultimately it's easy to see if you need a SecurityManager, isn't it? --- Comment out the code and run Then, if you wish, use -Djava.security.manager= and -Djava.security.policy= to experiment a bit with the things. - Peter
