and i want total number of checked checkboxes and their values using backing bean Holiday_Declaration.

Thank开发者_运维技巧s for any help...

Have following field in your managed bean

 private List<String> chk_weekedays;
 // getters/setters

Cover your component in an h:form and on submit access this list from some action
