  • Presentation Overview

Part 1

  • Project Requirements
  • Solution Landscape
  • Introduction to JSP

– Programming features – Application server features

  • JSP and Servlets
  • JSP and EJB
  • Container Vendors
  • Platform Selection Criteria
  • Part 2
  • Design Drivers
  • Application Model
  • Model/View/Controller Approach
  • Simple Forms
  • Complex Forms
  • OO Solution
  • Deployment
  • Security
  • Future developments

  • Project Background and Requirements

– Client and Project are Confidential – Security is Critical – Multi-Lingual

Phase 1:

– Bring client’s current business processes to the web ASAP – Very short design and development cycle – Small amount of custom functionality – Maximize reuse in phase 2 – Keep it simple

Phase 2:

– High volume eCommerce site – Lots of standard functionality:

  • Catalog, Shopping Cart, Payment, Personalization, Cross Selling, etc.

– Specific requirement not yet determined

  • Intro to JSP: Page Elements
  • Standard Tags
  • ‘Use Bean’
  • Session Management
  • Alternate Languages
  • Custom Tags

...<BODY> <%@ page language="java" import="com.acme.app.*, java.util.*" %> <jsp:useBean id="hist" scope="session" class="com.acme.app.histBean" /> <% Iterator itOrders = hist.getOrderList().iterator(); while (itOrders.hasNext()){ Order odr = (Order)itOrders.next(); %> <TR> <TD>Autrags-Nr.: </TD> <TD> <%= odr.getRenderer("odrNum").disp()%> </TD> <TD>Liefer-Datum:</TD> <TD> <%= odr.getRenderer("dvDt").disp()%> </TD> </TR> <% } %> </BODY></HTML>

  • Intro to JSP: App Server Features
  • Applications

– ‘Virtual Server’ – One of 4 levels of scope for a bean

  • Deployment

– Deployment Descriptors – WAR file

  • Security

– Forms based – Defined at Application Level

  • JSP Server remotlely connected to Web Server

– Dynamic pages must not be in DMZ :-) – Some support for Load Balancing / Fault Tolerance

  • JSP and Servlets
  • JSP extends Servlet API
  • Many features are actually inherited from Servlet specification
  • JSP spec requires implementations to compile JSP’s into Servlets
  • Strong relationship between versions of Servlet & JSP specs:

Servlet 2.1 JSP 1.0 Servlet 2.2 JSP 1.1

slide-9
SLIDE 9
  • JSP and EJB
  • JSP 1.1 / Servlet 2.2 define the equivalent of an EJB Web Container
  • JSP applications should be directly portable to EJB containers

  • Security
  • Standards Compliance
  • Upward compatibility w/ EJB
  • Delay decision for expensive, transactional, eCommerce

  • Conclusions
  • JSP defines an application server that is well suited to projects of small

to medium complexity.

  • JSP containers are an excellent starting point for organizations that

want to pursue EJB development, but are not ready to commit to the cost and learning curve of a full EJB product.
