3.2 New JSP & Servlets Technology


* JSR-053
* Servlet 2.3
–filters
–application Events
* JSP 1.2
XML Query for –jsp page
– Many improvements and enhancements
* The implementation of the Apache organization
–jakarta.apache.org/tomcat

3.3 JSP Tag Library


* JSR-052
* Standard JSP Tag Library
-Rich Features
–xslt
–xpath
– The process of other XML
Advancement of the –apache Organization (JAKARTA.APACHE.ORG/TAGLIBS)


3.4 Support of the framework


* Java EE system
* Jsp/servlet System
–struts
Advancement of the –apache Organization (jakarta.apache.org/struts)

3.5 JSP Tool Support


* Most of the cases are provided for the page author
– some are available for taglib workers
* already exists in some tools
– for example, Ultradev supports struts
* Forecast for nearly 6 months
– Standard taglib will appear, as well as a variety of other taglib

3.6 XML parsing and transformation


* JAXP 1.1
– Components of the next generation J2SE (JDK)
–dom Level 2
–xslt
– Combined with Trax (XSLT activation)
The Advancement of –apache Organization
* XSLTC
–xslt compiler
-Faster, smaller scripts

3.7 Data binding


Beans Long Term persistance
* Adelard
– Components of the next generation J2SE
– Data binding
* JavaBeans Long Term persistance
– Components of the next generation J2SE
-Graphical swing mechanism

3.8 XML Messaging


* XML Messaging
–jms
–ebxml
–jaxm
–message Beans (Java 1.3)

Outline
* JSP, Servlets & Java EE
* JSP and XML
* Status

1 JSP, Servlets & Java
1. 1 Java Platform

* Specification
* Compatibility Tests
* Reference Implementation (RI)
* Rich Functionality
–jsp and Servlets
–jdbc
–ejb
–jms
–connector to EIS (Java 1.3)

1. 2 Java Benefits

* Common Mindshare
–documentation
–training
–tool Support
* Portability
* Best-of-breed implementations

1. 3 Web Layer of Java
(Illustration 1)

1.4 Role of JSP and Servlets
* Entry point to Application
* Interacts with the exterior
* Usually through HTTP
* Client may be:
* Browser
* Applet
* Desktop Application (Java Web Start)
* Wireless Device
* Server Application (business-to-business)

1.5 JSP and Servlets
* Can is used in
–jsp & Servlet Container
–J2EE Container
* Common Mindshare
* Best-of-breed Implementation
* Wide Support

1.6 What is a Servlet?
* Extension mechanism
* Dynamic Content Generation
* Mapped to URLs
* Simple Architecture
* Managed by container

1.7 JSP Page
* A Textual document
* Describes a request–response map
* Servlet semantics

1.8 An example
<?xml version= "1.0" >
<%@ page contenttype= "Text/xml"%>
<%@ taglib prefix= "x" uri= "..."%>
<wml>
<card id= "Card1" title= "Flowers" >
<p>
Flowers available:
<br/>
<x:enumerate inventory= "Flowers"
Id= "Aflower" >
<%= Aflower.type%>
<br/>
</x:iterate>
<br/>
</p>
</card>
</wml>

1.9 JSP Page
* A Textual document
* Builds on
–template data
–dynamic Content
* Tool Friendly
* Abstraction using
–javabeans
–tag Libraries

1.10 Tag Libraries
* Abstraction mechanism
* XML Syntax
* Run-time Protocol
–integration into a JSP page
–easy to compose and customize
–managed by JSP Container
–simple protocol for Simple needs

1.11 Roles involved
* Page and Site Author
–creates Presentation from developer data
–expert in UI
–uses Tag Libraries & JavaBeans
–page Authoring Tools
* Developer
–provides access to data for page author
–expert in Server-side organization
–defines Tag Libraries & JavaBeans
–ides

2 JSP & XML
2.1 Uses of XML in JSP Technology
JSPs Pages
–consuming XML
–generating XML
–transforming XML
* JSP Pages as XML documents
* XML Configuration

2.2 Consuming XML
* Parse XML into objects (by developer)
–hand-coded
–using Adelard Technology
* Parse and Iterate abstraction
* Insert after transformation
–xslt

2.3 Parse into Object
