[snipped rest of stacktrace]

Try to replace forward slash / by backslash \ in your policy file path:

-Djava.security.policy=C:\jini2_0_002\lib\startup\services\reggie\start.policy

The policy file probably couldn't found, which caused the 'access denied" security exception.

Hmm... apparently it doesn't allow you to create (or change) the SecurityManager (access denied:
java.lang.RuntimePermission createSecurityManager). There seems to be a problem with the Java
security settings of the application.

Check inside the policy file (does it actually exist?, is it readable by the app?) and see if you
need to change some paths and values to match your environment. Can't help you on that any further,
you'll have to refer to the link you provided earlier.

[Another thought, but I don't think this is a problem: do you run the app on your own PC, or in a
controlled environment, e.g. a University or school computer lab? In the latter case it might be
possible that there are some 'global' Java security restrictions enforced, e.g. that the java
command is always executed with a SecrityManager (enforced by a 'global' policy file, e.g. in the
install dir of the JRE), causing it to refuse the replacement of the existing SecrityManager. As
said, I don't think this is the case, it's more likely a problem with the security settings in the
application]

i found what's wrong .
I changed the syntax of my policy file and that's work but the problem was
on my config files.
thanks for all and have a nice day
