The browsers can display a user/password dialog to provide a basic authentication mechanism. First, you have to define roles and users in the tomcat-users.xml file that you find in Tomcat s conf folder. Listing D-10 shows you what you should insert into tomcat-users.xml to define the canDoThis and canDoThat roles together with a couple of new users. Listing D-10. tomcat-users.xml Fragment <tomcat-users> <role rolename="canDoThis"/> <role rolename="canDoThat"/> <user username="aBloke" password="whatever" roles="canDoThis"/> <user username="bigCheese" password="yes!" roles="canDoThis,canDoThat"/> </tomcat-users> The tomcat-users.xml file is shared by all applications, but this doesn t prevent you from using the roles only for specific applications. Suppose that you want to use a password to protect all the pages inside a particular folder of an application. To do so, you have to edit the WEB-INF\web.xml file in the application s root directory. Listing D-11 shows you the code you should insert inside the <web-app> element. We ve highlighted the three main tags.

... <composite:implementation> <h:form> <h:inputHidden value="#{compositeComponent.attrs['product'].id}"/> <h:inputText value="#{compositeComponent.attrs['product'].name}"/> <h:commandButton action="#{compositeComponent.attrs['product'].onUpdated}" .../> </h:form> </composite:implementation> </body> </html>

if ( $_FILES['input']['type'] != 'audio/x-wav' ) { exit( 'Error: wrong Content-Type, must be audio/x-wav.' ); } // generate ticket $ticket = uniqid( "mp3-" ); // build dropPath $dropPath = "$dropFolder/$ticket.wav"; // get file, save in dropFolder if ( !move_uploaded_file( $upload, $dropPath ) ) { exit( "Error: unable to place file in queue." ); } // set permissions... chmod( $dropPath, 0644 ); // show initial wait message print $header; print "<h1>Your MP3 will be ready soon!</h1> <p>Your ticket number is $ticket.</p> <p><a href='$uri ticket=$ticket'>Redeem it.</a></p>"; print $footer; exit(); } // end _POST['encode'] is not empty } // end if ( empty( $_GET['ticket'] ) ) // mp3Interface.php continues When the user has submitted a file with a request for encoding, you begin processing that uploaded file. You check that the file is in the correct .wav format for encoding, generate a unique ticket ID, move the file to the drop folder and identify it with the ticket ID, and change its permissions so that it can be processed. You present the user with an opportunity to pick up the encoded file now; you send the ticket ID as a $_GET variable, just as in the form in the earlier section of the script, so that only one check for its existence will be required. // continues mp3Interface.php else { // $_GET['ticket'] is not empty // attempt to redeem ticket $ticket = $_GET['ticket']; // sanitize filename if ( strpos( $ticket, '.' ) !== FALSE ) { exit( "Invalid ticket." ); } // encoded file is: $encoded = "$dropFolder/$ticket.wav.mp3"; $original = "$dropFolder/$ticket.wav"; // check for ready mp3, waiting ticket, or invalid ticket // mp3 encoder deletes the original at the end of processing,

Listing D-11. web.xml Fragment <security-role> <role-name>canDoThis</role-name> <role-name>canDoThat</role-name> </security-role> <security-constraint> <web-resource-collection> <web-resource-name>This</web-resource-name> <url-pattern>/this/*</url-pattern> </web-resource-collection> <auth-constraint> <role-name>canDoThis</role-name> </auth-constraint> </security-constraint> <security-constraint> <web-resource-collection> <web-resource-name>That</web-resource-name> <url-pattern>/that/*</url-pattern> <http-method>GET</http-method> </web-resource-collection> <auth-constraint> <role-name>canDoThat</role-name> </auth-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> </login-config> As you can see, you first declare the security roles defined in tomcat-users.xml. Then you define two security constraints. Each security constraint can actually include several resources and authority constraints. The <url-pattern> subelements state which folders or pages require protection. Finally, you state that the BASIC authentication method should be applied. That s it! When you first attempt to access a page in a protected folder, the browser asks you to provide user identification and a password, as shown in Figure D-4.

To use the bar tag lib in p1.xhtml, you need to use its namespace URL. But what s its URL Because it has only a short name, its URL is always derived from the short name using this pattern: http://java.sun.com/jsf/composite/<short name>. In this case, it is http://java.sun.com/jsf/composite/bar. So, modify p1.xhtml as shown in Listing 5 29. Listing 5 29. Using the <pe> Tag in the Bar Tag Lib

The only way of logging out is to close the browser and reopen it. Now, after logging in, you re able to verify that the getAuthType method returns "BASIC" instead of null, getRemoteUsers returns "bigCheese" instead of null, isUserInRole("canDoThat") returns true, and getUserPrincipal() also returns a Principal object with name "bigCheese".
