3.2 新的JSP & Servlets技术
* JSR-053
* Servlet 2.3
– Filters
– Application Events
* JSP 1.2
– JSP页面的XML方式查询
– 许多改进和增强
* Apache组织的推行
– jakarta.apache.org/tomcat
3.3 JSP Tag Library
* JSR-052
* 标准的JSP tag library
– 丰富的功能
– XSLT
– XPATH
– 其它的XML的进程
– Apache组织的推进（ jakarta.apache.org/taglibs）
3.4 框架的支持
* J2EE体系
* JSP/Servlet体系
– Struts
– Apache组织的推进（jakarta.apache.org/struts）
3.5 JSP工具支持
* 大多数情况下是为页面作者提供的
– 有一些是为TagLib工作者提供
* 已经存在于一些工具中
– 例如，UltraDev支持Struts
* 近6个月的预测
– 标准的taglib将出现，还有各种其他的taglib
3.6 XML解析和转化
* JAXP 1.1
– 下一代 J2SE(JDK)的组成部分
– DOM level 2
– XSLT
– 和TRaX (XSLT激活)进行组合
– Apache组织的推进
* XSLTC
– XSLT编译器
– 更快，更小的脚本
3.7 数据绑定
Beans Long Term Persistance
* Adelard
– 下一代J2SE的组成部分
– 数据绑定
* JavaBeans Long Term Persistance
– 下一代 J2SE的组成部分
– 图形化Swing机制
3.8 XML Messaging
* XML messaging
– JMS
– ebXML
– JAXM
– Message Beans (J2EE 1.3)

JSP Technology and XML技术纲要
Eduardo Pelegri-Llopart
Sun Microsystems

提纲
* JSP, Servlets & J2EE
* JSP and XML
* Status
1 JSP, Servlets & J2EE
1。1 J2EE Platform
* Specification
* Compatibility Tests
* Reference Implementation (RI)
* Rich Functionality
– JSP and Servlets
– JDBC
– EJB
– JMS
– Connector to EIS (J2EE 1.3)
1。2 J2EE Benefits
* Common Mindshare
– Documentation
– Training
– Tool Support
* Portability
* Best-of-Breed Implementations
1。3 Web Layer of J2EE
（插图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 (B2B)
1.5 JSP and Servlets
* Can be used in
– JSP & Servlet Container
– J2EE Container
* Common mindshare
* Best-of-breed implementation
* Wide support
1.6 What Is a Servlet？
* Extension mechanism
* Dynamic
* Mapped to URLs
* Simple architecture
* Managed by container
1.7 JSP Page
* A textual document
* Describes a request – response map
* Servlet Semantics
1.8 一个例子
？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
