Security Violation, anyone can help me?

Question

Hi all, I explained my problem yesterday but i don?t have the exact error syntax of my problem. I�m trying to connect a system MSAccess database from a Windows 2000 ADV SERVER Machine, but when my jsp calls the Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") I recieve the following error:
JasperException: Security violation, attempt to use Restricted Class: sun.jdbc.odbc.JdbcOdbcDriver.
I never seen this message before and I?m waiting for replies.
Thx all

Hi Pedro,
You multiple posts shows the frustration you have. This problem is
nothing to worry about. Start bugfixing from the error stacktrace. java.security.AccessControlException: access denied java.lang.RuntimePermission accessClassInPackage(sun.jdbc.odbc) means some security setting prevents the program from accessing the
classes in package sun.jdbc.odbc during Runtime.
So you need to set the security permissions for that. Editing the
java.policy file should do the trick.
open the java.policy file in your $JAVA_HOME/jre/lib/security folder
(or the policy file which is used by your server) and add the foll
entries into it.. grant {
    permission java.lang.RuntimePermission
       "accessClassInPackage.sun.jdbc.odbc";
    permission java.util.PropertyPermission
       "file.encoding", "read";
  }; That should fix it I hope.
I had ran into the same problem when i was studying about applets.
Please refer the following urls for a detailed explanation. I got my
applet problem solved from there.
