JDBC Realm HTTP 403 problem

Posted on 2006-03-30
Last Modified: 2010-08-05

I have successfully implemented JDBC Realm for authentication. I can add new users and passwords to the tables in the MySQL database and assign roles which i have populated in the database (from the tomcat-users.xml, i just populated those roles that were present in the tomcat-users.xml) .

I had earlier used tomcat-users.xml file for authentication which contains the roles and users. What i tried to do was add new roles in the database and create users and assign those roles to the users. It gives me HTTP 403 error.

In other words, creating new users and passwords and assigning existing roles works. But if i create a new role in the Database, and assign it to a new users, it fails to enter.

The error looks like this:
HTTP Status 403 - Access to the requested resource has been denied


type Status report

message Access to the requested resource has been denied

description Access to the specified resource (Access to the requested resource has been denied) has been forbidden.


Apache Tomcat/5.0.28

Please help!!!!!!!!!!!!!!!!!!!!!

    You also need to set up resources acess in your web.xml correctly after you set up JDBC realm.
    especially looking for sth like this:

                    <description> accessible by authenticated users of the tomcat role</description>
                    <description>These roles are allowed access</description>

    I absolutely understood where the problem is!! Thanks for the help!!

    Can i ask you some more help??

    How can we set the web.xml in such a way that the <role-name> value is taken from the database??

    In detail, I have an appication running on struts and performs JDBC Realm authentication (programmed by me). I need also to add new user roles on the fly i.e., i have created JSP from where admin can add new user role (into the database) and also assign controls (acl.xml). Everything is done, but just because i need to add the role-name in the web.xml this will not work. Do you know how i can do it???

    I hope i am clear!!

    The problem i am trying to avoid is "Every time i make an entry to web.xml, i need to restart the server" which we cannot afford when the system goes into production.

         web.xml is static so I am afraid you can not do it on the fly.
         But good news is that you can programtically do it if you want. Use: HttpServletRequest.isUserInRole(<role>)

    web.xml only reads during web app initiation. Sorry, no way around. Refer to specification, the only choice is using isUserInRole which should be sufficient.

    what I mean is that programmtic authentication and authorizatio such as  isUserInRole is your only way.

    You can not change web.xml on the fly. It is static.
