Section 1: XML Web Service Standards

Objectives:

  • Given XML documents, schemas, and fragments determine whether their syntax and form are correct (according to W3C schema) and whether they conform to the WS-I Basic Profile 1.1.
  • Describe the use of XML schema in J2EE Web services.

    • So for the most part, we are looking at understanding XML, XML Schemas. There are plenty of resources on the web for this. Once you have a handle on this, you need to know the XML formats of specific things like WSDL. The rules that these need to conform to are outlined in the WS-I BP 1.1.
