1. Technology Comparison between JSP and Rails By Kwan Shing Yuen CS491B

2. Description Comparison two programming languages by creating online store web site Java (OO language) and JSP(J2EE) Ruby (Scripting language) and Rails

3. JSP version ( JSP version) Programming Language:Java 1.5 Development tool:Sun J2EE™ Development Kit 5.0 Integrated Development Environment:TextPad 4.7.3 32-bit Development Platform:Microsoft Windows XP Web Server: Tomcat ( port 8080 ) Database:MYSQL

4. Rails version ( Rails version) Programming Language:Ruby (ruby1.8.2-15) Development tool:Ruby on Rails framework Integrated Development Environment:TextPad 4.7.3 32-bit Edition Development Platform:Microsoft Windows XP Web Server:WEBrick 1.3.1 ( port 3000 ) Database:MYSQL

5. Book Store Feature Book search Shopping Cart Check Out Login ( admin ) Pending and Shipped Order List

6. Database

7. Database (Cont.)

10. Structure overview

12. Software Architecture MVC –Model –View –Controller

13. JSP Models –User.java –MyBook.java, MyBooks.java –CartItem.java, CartItem.java Views –userM.jsp –adminM.jsp –MyCart.jsp ……… Controller –Book_Controller.java

14. Rails Models –Book.rb –Order.rb –Cart.rb Views –Search.rhtml –Display_cart.rhtml –List.rhtml …………. Controller – book_Controller.rb, admin_Controller.rb, login_Controller.rb

15. Syntax Variable In Java: MyBook temp = new MyBook() In Ruby: @temp ( we don’t need to specific the type, it can be a object) eg. @temp = Book.new

16. Syntax (Cont.) Parameter In JSP: req.getParameter("id") -> in a String type In Rails: params[:id] -> can be any type

17. Syntax (Cont.) HyperLink In JSP: ISBN In Rails: "show", :id => @bookss.id %>

18. Development JSP has to code line by line JSP has more code in getting data from database

19. Rails It has a scaffold autogenerated Less code of getting data in MYSQL –Auto mapping to the database Create table books ( id int ………….. Book.rb –class Book < ActiveRecord::Base……. –…… –end

20. DEMO >rails depot create table products( id int not null auto_increment, name varchar(10) not null, primary key(id)); database connection > ruby script.generate scaffold Product Admin

21. Search in database Search in Database: In JSP: // Result rs= stmt.executeQuery("select * from books where id = 2"); while( rs.next() ) { int id = rs.getInt(“id”); } // Result rs= stmt.executeQuery("select * from books where isbn = ‘16349827’"); while( rs.next() ) { String isbn = rs.getInt(“isbn”); } //

22. Search in database In Rails: @id = 2 book = Book.find(@id) @ISBN = 16349827 @bookss = Book.find_by_ISBN @ ISBN
