Accounts of users

[Eric]

I want to make a page Web with accounts of users, in which the users can be registered and login, does somebody can guide to me?, how can I do that?

I did it that: when somebody does login I pay attention to the data base if that person already registered, I do session=req.getSession (true); and I keep like attribute from session the user's name. The problem is when other user does login, the page shows the first user's account.

if you use tomcat, attached the security of your project to this. you only must modify server.xml

Code:

<Realm  className="org.apache.catalina.realm.JDBCRealm" debug="99" 
             driverName="org.postgresql.Driver" 
          connectionURL="jdbc: postgresql://10.0.0.1:5432/DB" 
         connectionName="USER_DB" connectionPassword="PASSWORD_DB" 
              userTable="TABLE_USERS" userNameCol="FIELD_USER" userCredCol="FIELD_PASSWORD"  
          userRoleTable="TABLE_ROLLS" roleNameCol="FIELD_ROLL" />

and in the web.xml

Code:

<login-config> 
        <auth-method>FORM</auth-method> 
        <realm-name>MyFirst Protected Area</realm-name> 
        <form-login-config> 
                <form-login-page>/PAGE_LOGIN</form-login-page>  
                <form-error-page>/PAGIE_LOGIN_ERROR</form-error-page> 
        </form-login-config> 
 </login-config>

<security-role> 
         <role-name>ROLLS_THA_ACEPT_THE_SYSTEM</role-name> 
 </security-role>
