I have some doubts related to Listeners. I actually have a database called LOGIN and I have one table that has the username and password details. I have a page that asks for the username and password and upon submit, it checks the values in a database and takes me to another page called inbox. I want to try this code using Listeners. The K&B book says this on page 168. My question is what will be the param-name and param-value for this?? And how will my attribute class look like?? Anyone help me please!!
Thanks in advance.

Did a rm -R / to find out that I lost my entire Linux installation!
It is best to use declarative security rather than have a listener check credentials every time. If you still want to do it, use the isUserInRole method to check if the user is logged in. I am not sure why you would want an attribute to be associated with this filter.
