XML schemas The purpose of schemas Motivation for schemas Mapping a DTD to a schema Various data types in schemas Mapping schema types with database types Writing a simple schema XMLSchema namespace Deciding on default and target namespace Simple types Structuring your schema- referencing and inlining Advantages of referencing and inlining Complex types Sequences and choices Named types Scope of the declared types Extending the primitives Inheriting via extension Manipulating with the facets of each type Inheriting thru restriction Creating user defined data types Declaring attributes Simple Content +examples and exercises. Day 2 : Introduction to Web Services Introducing Web Services A sample scenario of a Web Service Introduction to SOAP The history of SOAP Why SOAP? The SOAP message exchange model Relation to XML SOAP Envelope SOAP encoding style attribute Envelope versioning model SOAP Header SOAP body SOAP fault SOAP Encoding Rules for encoding types in XML Simple types Polymorphic accessor Compound types The SOAP Mapping Registry Default values Using SOAP in HTTP SOAP HTTP request SOAP HTTP response The HTTP extension framework SOAP HTTP Examples Day 3 : Changes in SOAP 1.2 Java API for XML Messaging (JAXM) and SAAJ Overview of Messaging as a distributed application mechanism Overview of JMS JMS as the infrastructure for JAXM Overview of JAXM Messages Connections Messaging Providers Getting a Connection Creating a Message Populating a Message Sending a Message Client without a Messaging Provider Client with a Messaging Provider Adding Attachments Java API for XML based RPC (JAX-RPC) What is JAX-RPC? A Simple Example: HelloWorld HelloWorld at Runtime HelloWorld Files Overview of Steps Setting Up Coding the Service Definition Interface and Implementation Class Compiling the Service Definition Code Creating the Configuration File Generating the Stubs and Ties Creating the Deployment Descriptor Packaging the Service Definition Deploying the Service Definition Coding the Client Compiling the Client Code Running the Client The Dynamic Invocation Interface When to Use DII A DII Client Example Discussion on some common design issues
