I am trying to run my first Java RMI client-server app with the following command line input.
java -cp eclipse-workspace -Djava.rmi.server.codebase=file:/eclipse-workspace -Djava.rmi.server.hostname=localhost -Djava.security.policy=rmidemo.policy -Djava.security.debug=access ct/ExamEngine
The rmidemo.policy file:
grant codeBase "file:/Users/user/eclipse-workspace/rimdemo/src/ct" {
permission java.security.AllPermission;
};
The stack trace is:

[EDIT] If it wasn't already clear the issue lies with the security manager, when I removed it, it worked, but it is necessary for this app, so I need to figure out a way around this.
