| 00.01 | Welcome to the spoken-tutorial on Creating and viewing inventories. |
| 00.07 | In this tutorial we will learn to: |
| 00.09 | 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 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 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 we 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 equals 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, BookName,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 the 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 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 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 list of books. |
| 04.43 | Here, first we obtain the books from request. |
| 04.48 | This HTML table will display 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 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 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 | So, 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 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 borrowed book details |
| 08.45 | And to display the books borrowed by logged in user |
