[urls]
# The /login.jsp is not restricted to authenticated users (otherwise no one
could log in!), but
# the 'authc' filter must still be specified for it so it can process that
url's
# login submissions. It is 'smart' enough to allow those requests through
as specified by the
# shiro.loginUrl above.
/login.jsp = authc
/logout = logout
/account/** = authc
/remoting/** = authc, roles[b2bClient], perms["remote:invoke:lan,wan"]


please suggest me by finding the mistakes...
any help is appreciated.
thanking u:)
