RMI: Naming.bind raises AccessControlException

[Roland Zumkeller]

Hi,
I'm trying to use RMI, but encountering problems when trying to
bind an object to a port.

I first start the registry with this command (at the
command prompt):
start rmiregistry 2005

Then execute the following code:
System.setSecurityManager(new RMISecurityManager());
MyRMIclass r = new MyRMIclass();
Naming.bind("//deep_thought:2005/MyRMIclass", r);

What I get is a java.security.AccessControlException on the bind
method. (Below you can find the whole stacktrace.)
The name of my machine is DEEP_THOUGHT, I'm using NT4 and JDK
1.2.1.

Thank you for your help.

Roland

Hello,

You must configure the necessary Java security permissions using a Java
policy file in Java 1.2 or later. The AccessControlException occurs when a
resolve is attempted in the Socket code. The JRE installation policy file
defining the security policy for all Java applications ) exists in
~jre/lib/security/java.policy - but an application may use a specific
security policy.

Permissions are of the form:

permission java.net.SocketPermission "localhost:2005", "listen, resolve"

Security in Java 1.2 is involved - its best to consult the tutorial -
