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

  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.)

  8. Database (Cont.)

  10. Structure overview

  11. Software Architecture • MVC • Model • View • Controller

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

  13. 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

  14. 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

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

  16. Syntax (Cont.) HyperLink In JSP: <a href="show.jsp?id=3">ISBN</a> In Rails: <%= link_to @bookss.ISBN, :action => "show", :id => @bookss.id %>

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

  18. 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

  19. 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

  20. 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”); • } • //

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