We ve come a long way we ve created the majority of the SneakyCat application. Let s take our application for a spin. Let s start the development server and see what we can see. At a command prompt, issue the following commands: $ cd SneakyCat $ script/sneakycat_server.pl -r -d You will see the SneakyCat application server start up and display the normal dev server debugging information. Toward the end, you will see a box that looks similar to the following: [debug] Loaded Path actions: .-------------------------------------+--------------------------------------. | Path | Private | +-------------------------------------+--------------------------------------+ | / | /default | | / | /index | | /ideas | /ideas/index | | /ideas/share | /ideas/share | | /people | /people/index | | /people/login | /people/login | | /people/logout | /people/logout | '-------------------------------------+--------------------------------------' You can connect to your server at http://mylocalserver:3000 Note that this displays all the actions we defined and tells us how to connect to the dev server. If we cut and paste this URL into our browser, we will see something like Figure 8-1.

[G]o!: Selecting this option prompts you to select a file path for a log file. The log file augments feedback provided by the status window, and is a separate ASCII text file that creates one row per processed file, regardless of success. You can use the log file to locate any OCR text files that failed to load during the procedure. You enter the name of the log file (of your choosing) and then click the Open button. This triggers the actual load. When the load procedure is activated, the CPL takes over and processes each database record and each associated OCR text file. The CPL displays a running tally of the number of database records processed. As the CPL attempts to load each database record, the results of the procedure are recorded in the log file. If the CPL encounters a value in the field selected from the option [I]mage field select that doesn t have a corresponding text file of the same name, an error message is created as a separate row in the log file. The log file created by this particular load is displayed in Figure 7-22; recall that the file 0010008.txt was purposely misnamed to generate an error message.

Figure 8-1. Front page for the SneakyCat application You are, for the first time, seeing what SneakyCat looks like. There is not a lot to see here, mainly because SneakyCat does not know who you are. Let s change that click the Login link in the navigation bar and sign in. You will be SneakyCat s neighbor, so log in with the username neighbor and the password bar123. Upon login, you will be directed back to the screen you saw before, only now it looks a bit different, as shown in Figure 8-2. Notice now that you can see the more secret thoughts of SneakyCat. Notice also that the Login link in the navigation bar has disappeared, replaced by a Logout link. If you click Logout, you will see a page telling you your logout was successful. If you go back to the ideas page by clicking Home in the navigation bar, you will go back to seeing only SneakyCat s public thoughts. Congratulations, you now have a complete functioning web application with basic authentication! In the next section, we will explore another important aspect of authentication in web applications: authorization.

Note The two leading SQL*Plus commands in Listing 10-6 are used only to make the results more readable. 11 discusses these (and many other) SQL*Plus commands in more detail.
