AccessControlException hocuspocus

[Juhan Voolaid]

When I try to make a RMI connection with my client application, I get AccessControlException.
Solution for that would be configuring the security policy like that:
java -jar -Djava.security.policy=client.policy runme.jar

The client.policy file:

grant codeBase "file:runme.jar"
{
	permission java.security.AllPermission;
};

But the instructions clearly say that: "Your programs must not require use of command line property specifications".

So what are my options?

I have read that security policy is only required when the stubs are not provided, but I have included them - how do I test that anyway?

Ok, found it.

The problem was, that I set new security manager in my code:
System.setSecurityManager(new RMISecurityManager());

Just had to delete it and it worked fine. I accidentally copied that code from RMI tutorial.

if you use RMI and have the security manager (which is forbidden) you automatically failed.

Hi everybody,
I hav the Bodgitt & Scarper assignment.
I must not require the installation of a security manager. Does this mean I must not include a policy file?
TIA

Yep. Without specifying any security policy and not doing that:
System.setSecurityManager(new RMISecurityManager());

... my application works without problems.
