Time | Narration |
00:01 | Welcome to the spoken-tutorial on Creating and viewing inventories. |
00:07 | In this tutorial, we will learn: |
00:09 | To modify the login page to redirect to admin page |
00:14 | To fetch all the book details |
00:17 | To fetch borrowed book details |
00:20 | To display the books borrowed by a logged in user. |
00:25 | Here we are using: |
00:27 | Ubuntu Version 12.04 |
00:29 | Netbeans IDE 7.3 |
00:32 | JDK 1.7 |
00:34 | Firefox web-browser 21.0 |
00:38 | You can use any web-browser of your choice. |
00:42 | To follow this tutorial, you must have knowledge of: |
00:45 | Basics of Java Servlets and JSPs |
00:50 | Database and validation of fields. |
00:53 | If not, for relevant tutorials please visit our website. |
00:57 | Now, let us switch to NetBeans IDE . |
01:01 | I have created the Books table. |
01:04 | You can see the different fields in the table. |
01:08 | I have inserted 10 books into this table. |
01:12 | I have created Checkout table to store borrowed books. |
01:18 | I have inserted 5 entries into the Checkout table. |
01:24 | I have also created a model for Book and Checkout. |
01:29 | Book.java is a book model. |
01:32 | And Checkout.java is a checkout model. |
01:37 | Now, come to the browser. |
01:40 | Let us login as the admin. |
01:43 | So, I will type the username and password as admin. Then click on Sign In. |
01:51 | We can see that we come to the Admin Section Page. |
01:55 | We will come back to this page. Now let us switch to Netbeans IDE. |
02:02 | We will see, how we modified the GreetingServlet to redirect to Admin Page. |
02:08 | Let us see the GreetingServlet.java. |
02:13 | Here we check if username and password equal admin. |
02:19 | If yes, then we redirect to adminsection.jsp. |
02:25 | We have already seen how to forward to another page using RequestDispatcher. |
02:32 | Now, switch back to the browser. |
02:35 | We have two options here. |
02:37 | We will click on the radio button for List Books. |
02:41 | Then click on Submit button. |
02:44 | Here, we can see that we have the list of all the Books. |
02:49 | It has all the details like- Book Id, Book Name, Author Name, ISBN, Publisher, Total Copies and Available copies. |
02:59 | Now, I will show you how this is done. |
03:03 | Switch back to the IDE. |
03:05 | Now, let us come to adminsection dot jsp. |
03:10 | Here we have two radio buttons. |
03:14 | The first one is to list all the books. |
03:19 | We can see that in adminsection dot jsp, we have form action equal to AdminSection. |
03:28 | Now, Open AdminSection dot java. |
03:32 | Here, this checks the option that we click on. |
03:36 | We clicked on List Books. |
03:39 | So, this part of the query will be executed. |
03:44 | We execute the query to fetch books from Books table. |
03:49 | Next, we create ArrayList to store the details of the books. |
03:55 | Then we iterate through the result set. |
03:59 | We create the Book object. |
04:03 | We set BookId into the Book object. |
04:08 | Similarly, we set other attributes of the book into the Book object. |
04:16 | Then we add book object into the books list. |
04:21 | Then we set the ArrayList books into the request. |
04:26 | Then we forward the request to listBooks.jsp using RequestDispatcher. |
04:33 | Now, we come to listBooks.jsp. |
04:38 | In this page, admin can view the list of books. |
04:43 | Here, first we obtain the books from the request. |
04:48 | This HTML table will display the details of the books. |
04:54 | So, we will iterate through the book list. |
04:58 | Here we display the BookId of the book. |
05:02 | Similarly, we display other attributes of the book. |
05:07 | This is how we display the list of books. |
05:11 | Now, switch back to the browser. |
05:14 | Click on List Borrowed Books. |
05:17 | And click on the Submit button. |
05:20 | We see a list of all the Books issued. |
05:24 | It has details like Transaction Id, Book Id and Username. |
05:29 | Now, I will switch back to the IDE |
05:32 | and show you the code for the same. |
05:35 | Go to AdminSection.java. |
05:38 | We had clicked on List Borrowed Books. |
05:42 | So menuSelection is equal to List Borrowed books. |
05:47 | The steps are similar to what we saw for List Books. |
05:53 | We execute the query to fetch borrowed books details from the Checkout table. |
05:59 | Then we iterate through the borrowed books |
06:02 | and set it into request as checkout attribute. |
06:07 | Now, we come to listBorrowedBooks.jsp. |
06:12 | Here we obtain checkout from the request. |
06:17 | We iterate through the Checkout list |
06:20 | and here we display the attributes of the Checkout. |
06:25 | This is how we display Borrowed Books. |
06:28 | Now, switch back to the browser. |
06:30 | In the borrowed books page, we have one more list. |
06:36 | The list of books issued when the current date is more than the return date. |
06:43 | Switch back to IDE to see the code. |
06:46 | This is done in the same way as we did for Borrowed Books. |
06:50 | The only difference is in the SQL query. |
06:56 | In the query, we give the condition: return_date less than now() order by transaction_Id. |
07:05 | Now, I will show you the interface for a normal user. |
07:10 | Switch back to the browser. |
07:12 | Come back to the login page. |
07:15 | I will login as mdhusein. |
07:20 | Type the password as welcome |
07:22 | and click on Sign In. |
07:25 | We get a Success Greeting Page. |
07:28 | It has the books currently borrowed by the user. |
07:32 | It has details like Transaction Id, User Name, Book Id and Return Date. |
07:39 | Now, let us come back to the IDE. |
07:43 | Now we go to GreetingServlet.java. |
07:47 | We display the books issued in the same way as we did for the admin. |
07:53 | Here the difference will be that we have to display the books for the logged in user. |
08:02 | So, I get the username from this line. |
08:05 | Then we fetch the details of borrowed books |
08:10 | with the condition username is equal to the logged-in user. |
08:14 | So, we get the list of books issued for the corresponding user. |
08:20 | Then, in successGreeting dot jsp we will display the list. |
08:27 | This is how your successGreeting dot jsp will look. |
08:32 | In this tutorial, we have learnt to: |
08:35 | Modify the login page to redirect to admin page |
08:39 | To fetch the book details |
08:42 | To fetch the borrowed book details and |
08:45 | To display the books borrowed by a logged in user. |
