Codebase setting in a local network

Hello,

Im now confronted with a codebase setting problem in a network:

Right now Im running Client and Server on the same machine and I have the Codebase Setting on the server like that:

-Djava.rmi.server.codebase=file:/C:/RMINORMICEXAMPLE/SERVER/NEWSERVER/bin/

This start-argument works fine, when Client and Server are running on the same machine.

Now I want the same setting to work in my local network. With this setting it will of course not work, because this setting only works when Client and Server are on the same machine.

Now expect that my Server has the IP-adress 192.168.0.3 and my Client has IP 192.168.0.2.

Is it possible to set the codebase to 192.168.0.3 with the directory path C:/RMINORMICEXAMPLE/SERVER/NEWSERVER/bin/ so that the Client gets the classes from the Server in that path.

I really tried a lot, but it didnt work.

THX for your help

Hi,

I think I know how it should work, but it doesnt ;-)

If I put a directory on the network, I must give it a name. In my example the name is "bin".

And then I put the argument of the VM to the following:

-Djava.rmi.server.codebase=file://192.168.0.3/bin/

But when I start my application I get the following exception:

Ausnahme: java.security.AccessControlException: access denied (java.io.FilePermission \\192.168.0.3\bin read)

java.security.AccessControlException: access denied (java.io.FilePermission \\192.168.0.3\bin read)
