RMI: AccessControlException: access denied 1

[TheMillionDollarMan]

Help.
Win 2k, Java SDK 2.

I am trying to run an example from SUN but failing. When I try to invoke the server I get the error message below. I get this error even if my host computer name is not correct.

Can anyone offer me some advice?

Thanks

Registry created on host computer DBrownFe on port 10002
Remote HelloService implementation object created
Exception in thread "main" java.security.AccessControlException: access denied (
java.net.SocketPermission DBrownFe resolve)

In JAVA_HOME\jre\lib\security there is a file called "java.policy". This controls permissions of the JVM at Runtime. I think the reason why you cannot invoke your server is beacause you are not allowed to resolve Socket/URL's according to this policy.

Try adding a line in this file on the global grant section :

permission java.net.SocketPermission "localhost:1024-", "listen,connect,resolve,accept";

THANKS!

You have at least started me in the right direction.
I saw an entry in the fileyou mentioned already. However I couldn't get your suggestion to work...

Now I can start the server without any problems (before i wasn't possible).

The only problem I have now is that the client can't get permission to use the server (contact is made yet SocketPermission is denied).

checkCreateClassLoader()
java.security.AccessControlException: access denied (java.net.SocketPermission 123.123.123.123:10027 accept,resolve)
at java.security.AccessControlContext.checkPermission(AccessControlConte
xt.java:269)
etc ....

Try adding in you java.policy file the below :

grant codeBase "file:C:/where_my/java_rmi/classes_live/*" {
permission java.security.AllPermission;
};

and also do the same on the client ... come back if it still doesn't work !

hey!!

You are the best.

I saw an entry in the java.policy like the one youi mentioned above only it was pointing to $JAVA_HOME\lib\ext.

Your suggestion worked.
Now I can leave this line of code in the example given:

System.setSecurityManager( new RMIServerSecurityManager() );


Thanks again!
