 关于java.security.AccessControlException: access denied 的解决方法

    E:\jre6\lib\security(本人路径)，在grant里增加2个语句:

（加前2句时，并没起作用；加了第3句才解决）

permission java.lang.RuntimePermission "accessClassInPackage.sun.jdbc.odbc"; permission java.util.PropertyPermission "file.encoding", "read"; permission java.security.AllPermission;
