RMI security problem

[chi Lin]

Hi,
I follow RMI example code on one book, all files compile OK,
when I tried to run the code, I got some exception message like,
java.security.AccessControlException : access denied
if I comment out the following line, whole thing runs OK
// System.setSecurityManager( new RMISecurityManager());
could someone advise how can I fix the security problem ?
thx

depends on your programm, when you set a SecurityManager. Your programm's access to system resource will be checked against your security policy normally decided by a file $(JAVA_HOME)/jre/lib/security/java.policy.
e.g. If you want to read a file then you need proper FilePermission to be set up in the policy file. So make sure you configure your policy file so that your program's access is allowed.
