java.security.AccessControlException: access denied
(java.lang.RuntimePermission accessClassInPackage.sun.jdbc.odbc)
(java.lang.RuntimePermission accessClassInPackage.sun.jdbc.odbc)
.这是因为applet在没有被允许的情况下去获取系统资源.
同时,错误提示需要一个RuntimePermission,它将使applet去获得sun.jdbc.odbc 包.所以
可以把java包修改一个关于安全的一文件.
具体做法是:找到jre包,/Java/jre1.6.0/lib/security,在这个包下面有个java.policy文件,打开编辑它:
在grant里增加2个语句:
permission java.lang.RuntimePermission "accessClassInPackage.sun.jdbc.odbc";
permission java.util.PropertyPermission "file.encoding", "read";
permission java.util.PropertyPermission "file.encoding", "read";
再关闭ie,重新运行
增加第二个语句是因为让applet能读一些二进制文件.不然可能会出现
java.security.AccessControlException:
access denied (java.lang.RuntimePermission
file.encoding read)
错误.
access denied (java.lang.RuntimePermission
file.encoding read)
错误.
