I have some more question, suppose I have 3 users whome I want to give different menu. First I'll make a permission form there the permission menus names will be granted to them and store this names into the database. Now question 1: how do I'll get the names to the menus that I give permission to the corrseponding user.
After the user loged on the system, I have to generate the menu for him. So I think I have to collect those names from the database and construct the menu. Here question is how I'll contract a permissionAdapter for this specific user.
I don't know whether I could help you to understand the problem, in summary I want to generate menu according to a specific user.
Thank you,
Mahbub

Permissions are handled in a very generic and flexible way. A MenuDisplayer may take a PermissionsAdapter (as specified in the jsp tag) in which it asks it if a menu isAllowed(menuName). The only thing you have to do is provide the PermissionsAdapter. However, note that not all of the MenuDisplayers utilize PermissionsAdapters at this time.
The *only* permissions checking provided for by default is through the use of the RolesPermissionsAdapter in which it checks to see if a menu is associated with the current user's role. The roles are specified in the menus defined in the XML file. If you wish to perform your own form of permissions checking, then you'll need to implement your own PermissionsAdapter. Hence the name. It's an adapter that you provide so that struts-menu can work with your own permissions checking mechanisms. Whether that's through the use of a database, ldap, jaas, or whatever is up to you. struts-menu does not care because it only talks to a PermissionsAdapter. It's up to you to provide one (or use the included role based one).
Let me know if you still have any problems or questions about this.
BTW, there is a struts-menu-user mailing list:
