Does anyone know what these error means?

Hello,
I'm running my rmi client and got the following errors.

java.io.FileNot FoundException: \logs\new.log (The system cannot find the path specified)

and

Does anyone have any suggestion on how to fix these two problems?

It's just one error: every RMI service has to protect itself against abuse; you must
have installed a security manager that forbids the creation (or opening) of files.
A lean and mean trick is to install the following (empty) security manager:

import java.security.Permission;
public class FakeSecurityManager extends SecurityManager {
	/* allow everything: */
	public void checkPermission(Permission perm) { }
	public void checkPermission(Permission perm, Object context) { }
}

Before you start your RMI server install that (fake) security manager. Note that
this is not a solution, just a way to get rid of any security checks.

kind regards,

Jos
