我如何在symfony2中拥有自定义访问被拒绝页面

I am using JMS Security bundle to secure methods and controllers. When non previleged user access the secure page then i get this error

Token does not have the required roles.

Is there any way , i can make that custom page and more defined error message

If JMSSecurityExtraBundle answers you with a 403 error [and it should], you may customize it following Symfony guidelines.
