Design and Implementation of Web services-oriented Application B. Ramamurthy 11/30/2018

Introduction In this lecture we will learn methods for designing and implementation of WS-oriented projects. We will cover the entire lifecycle starting from unified modeling language (UML) to deployment and execution. After this lecture you should be able to design a solution for project and implement it. 11/30/2018

Topics UML tool: demo version of rational rose Use case diagram Class diagram Netbeans 6.1 IDE (Integrated Development Environment) Simple Java application Simple Java class Create a web service and deploy web service Applications (Java, Web-JSP) to consume WS End-to-end WS-oriented application 11/30/2018

Use Case Diagram Used in defining the system Example: your project 11/30/2018

Class diagram Used in specifying the implementation using classes and object-oriented principles. Example: calculator 11/30/2018
