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>
