I did not use any code like: if (System.getSecurityManager() == null) {System.setSecurityManager(new RMISecurityManager());} in both server side and client side. because I have not use jar yet, so in client side, I use command: java suncertify.fbnClient.FBNPanel hostname portNumber datafilename. in server side I use command: java suncertify.fbnConnectionFactoryImpl portNumber datafilename(s) The system tells me that access denied. it means that SecurityManager has some problem. Please help me. thanks.
Two things. 1. make a policy file that grants all access for the client. 2. Don't use a SecurityManager on either side, you don't need it at anytime. Mark
