The course yields 6 ECTS-credits

Prof. Dr. Wolfgang May
Assistants: Dr. Franz Schenk, Daniel Schubert

Prerequisites:

• Successful participation in the module "Semistructured Data and XML" (either in summer 2009 or before).
• Successful participation of the "General Programming Lab/Allgemeines Programmierpraktikum" (or an equivalent course).

Course Description

The practical training builds upon the lecture Semistructured Data and XML. The training uses the concepts of the XML world: DTD, XPath, XQuery, XSLT, XLink, XML Schema, SQL/XML, XML APIs for Java (SAX, DOM, JAXB), and Web Service infrastructure (Apache Tomcat).

• The first part of the course uses the geographical sample database "Mondial" in its XML version.
• The second part is intended to be carried out in a project-style, developing an application scenario using Web Services, Java, and XML.

Time Schedule

Part I: Basics, concepts and languages around XML that should be known from the summer lecture.

• 1. Lecture: 21.10. (Mi), 10-12 ct SR 2.101: Introduction, Formalities, Recall XML, XPath, XQuery.
  1. Unit: Exercises to XPath, XQuery (including user-defined functions), XSLT
  Most recent W3C XPath 2.0 Working Draft.
  Most recent W3C XQuery 1.0 Working Draft.
  Most recent W3C XQuery 1.0 Functions and Operators Working Draft.
  Most recent W3C XSLT 2.0 Working Draft.

Part II: Web Services, XML and Java

• 2. Unit: 18.11. 10-12h SR2.101: course/overview of XML and Java.
  Slides: XML Schema, XML and Java,
  Software and codefragments to download.
  The exercises to this unit exhibit the typical features of each of the concepts in comparisons:
  • DOM: The Java API for handling XML trees (we use jdom)
  • JAXB: mapping XML element types to Java classes based on XML Schema
  • Exercise: DOM vs. JAXB
  • SAX: Stream-Based API
  • StAX: another Stream-Based API
  • Exercise: SAX vs. StAX
  • XML for data exchange and Web Services: using the Tomcat WebService Container and communication via HTTP
  • Exercise: communicating/cooperating Web Services
