[Problem Description]

In this exam you are going to implement a web application that reads movie box office data from a text file, and displays the data in a table that supports paging. A sample box office data file can be downloaded from here (the same file is also available on the CS server under the /tmp directory so you don't have to copy it there).  Note that the box office information about a movie consists of seven fields: this week's box office ranking, last week's box office ranking, title, weekend gross, cumulative gross, the number of weeks that the movie has been released, and the number theaters in which the movie was shown. Fields are separated by comma in the file.

Your application should consist of a JSP page BoxOffice.jsp and a Java bean BoxOffice.java. You may use more JSP pages or Java classes if necessary, but note that no scripting elements or JavaScript is allowed in the JSP page(s).

[Implementation]

When BoxOffice.jsp is requested without any parameters, it displays the first 5 movies in a table as shown below:

Pages: [Previous] 1, 2, 3, 4, 5, 6, 7, 8 [Next]

This Wk Last Wk Title Weekend Gross Cumulative Gross Rlse Wks # of Theaters 1 - Saw II 31725652 31725652 1 2949 2 - The Legend of Zorro 16328506 16328506 1 3520 3 - Prime 6220935 6220935 1 1827 4 2 Dreamer: Inspired by a True Story 6132856 17374339 2 2491 5 3 Wallace & Gromit: The Curse of the Were-Rabbit 4302316 49694983 4 2935

When a user clicks Previous, Next, or one of the page numbers, the corresponding movie listings should be displayed, for example, the following table should be displayed when the user clicks page 3:

Pages: [Previous] 1, 2, 3, 4, 5, 6, 7, 8 [Next]

This Wk Last Wk Title Weekend Gross Cumulative Gross Rlse Wks # of Theaters 11 6 Elizabethtown 2382813 22699053 3 2137 12 12 "Good Night And Good Luck." 2003682 7239225 4 272 13 8 In Her Shoes 1717152 29225030 4 1402 14 9 A History of Violence 1351883 28542075 6 1011 15 80 G 1280851 1922579 7 495

Note that

• A user should be able to change the number of movies displayed in a page by passing a request parameter n to BoxOffice.jsp. For example, http://some.host/BoxOffice.jsp?n=10 should set the number of movies displayed in one page to 10.
• The number of pages should not be fixed. It should be calculated based on the number of movies in the box office data file and the number of movies to be displayed in one page.
• The page number of the currently selected page should not be "clickable". Similarly, the Previous page link (or the Next page link) should be removed if the first page (or the last page) is selected.

[Grading Criteria]

• Read data (15pt)
  
• Basic paged display (50pt)
• Change number of movies per page (10pt)
• Enable/disable links (10pt)
• Everything works correctly on the CS server (15pt)
• midterm.html is missing or doesn't have the link to BoxOffice.jsp on the CS server (-5pt)
• Please do not modify your files on the CS server after the due time. Doing so will be considered cheating.
