Sorry, here's what I do:
I have a web application and used Tomcat's Authentication mechanism called
JDBCRealm. I had to edit server.xml to do so (this is not really the details
I entered, it's just an example):
<Realm className="org.apache.catalina.realm.JDBCRealm"
driverName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
connectionURL="jdbc:microsoft:sqlserver://kebab.ucsd.edu:1433"
connectionName="CSE135_XX" connectionPassword="XXXXXXXX"
userTable="users" userNameCol="user_name" userCredCol="user_pass"
userRoleTable="user_roles" roleNameCol="role_name" />
Then I created the according tables:
create table users
(
user_name varchar(15) not null primary key,
user_pass varchar(15) not null
);
create table user_roles
(
user_name varchar(15) not null,
role_name varchar(15) not null,
primary key( user_name, role_name )
);
There is a user admin in the table "users" with "admin_role" (in the table
user_roles). There are other users with other names and other roles.
The web.xml got these additional entries:
<security-constraint>
<web-resource-collection>
<web-resource-name>SecurePages</web-resource-name>
<description>Security constraint /secure</description>
<url-pattern>/secure/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/loginerror.jsp</form-error-page>
</form-login-config>
</login-config>
<security-role>
<role-name>admin</role-name>
</security-role>
This is everything (or at least the most important things) I had to do to
configure everything. Now what I want to know is, which user is logged in at
a certain moment ... I want to know it when I create JSPs for example to
show the user's name (equal to the name in the users table).
Do you know what I meant to achieve? I don't want to get the database's
user, which would be "CSE135_XX" in the above JDBCRealm example ...
