java - Roles in JSP and Servlet -


I want to create an application with three types of user: admin, professional and ordinary users will see all the special pages, so Should I use roles for a good example or tutorial of a person how to do it? Create a DataStore firstly the users and the roles and relationships between them. The simplest option would be a SQL database with a user , role and user_roles tables.

Then there are basically two ways to achieve this in the JSP / servlet side.

  1. The easiest to get started, but it will end up for long lasting maintenance. You must use the login subletter to create an HTML / JSP login form, a login sublett, login the user and login so that it can check if the user is logged in or / or access to requested resources. . Use

  2. You just have to create an HTML / JSP login form and for the rest it goes to all the web.xml and server scope seminars is.

Specific page content / components based on the user's role to display, you can use JSTL's flow control tag: & lt; C: if & gt; and & lt; C: select & gt; .

But I do not think the code is capable of changing the color of each variable declared....
