java.security.AccessControlException:access denied (java.io.FilePermission)
hi
i have gone through so many threads asking the same question and i have tried everything given in solution but no use
this is my scenario
i am using eclipse to run my rmi program
i run my rmi_registry
i start my rmi server- with these in VM arguments-Djava.security.policy=e:\aditi\cmpe273\lab\lab4_aditijain\wideopen.policy
-Djava.rmi.server.codebase=file://lab4_aditijain/class/
the policy file look like this
grant{
// Allow everything for now
permission java.security.AllPermission"","";
permission java.io.FilePermission"E:/aditi/cmpe273/lab/lab4_aditijain/-","read";
};
but i get this error:
Exception: access denied (java.io.FilePermission \\lab4_aditijain\class read)
