Example

12. WebSphere Architecture

13. WebSphere’s Architecture example

14. Some hardware requirements
quite modern PCs
advised IBM zSeries
N.B.: differences between Server and Client

15. Some software requirements
Operating System:
Windows XP Professional SP1a
Linux
Sun Solaris
Other…
A lot of applications are included (HTTP server)

16. HTTP server WebSphere HTTP plug-in for the HTTP server.
uses an easy-to-read XML configuration file to determine whether a request is handled by the Web server or the Application Server.
uses the standard HTTP protocol to communicate with the Application Server
uses secure HTTPS for the configuration, if required

17. What are advantages?(1)
installation and customization are simple for administrative task
very good when it’s ready
there are a lot of useful tools:

26. Glossary(1)
E-business on demand: the idea of paying only for the IT and business processes you need, when you need them
Service Oriented Architecture (SOA)

27. Glossary(2)
EAR files - Enterprise application archive consisting of JAR files (EJB, Java code) and XML configuration files.

28. Glossary (3)
Enterprise JavaBeans are server-side components that use services such as life-cycle management, transactions, security, database connectivity, and more. They provide application business logic and data access.
Servlets and JavaServer Pages are server-side components used to respond to requests from HTTP clients. They provide presentation and control client interaction with applications.

29. Tool examples(1) WebSphere Studio: WebSphere Studio Workbench:
unit test environment
visual editors
user interface for the latest Web technology
a wizard for creating servlets
J2EE EAR deployment support ……
WebSphere Studio Workbench:
open tool
implements the same functionality of Eclipse

30. Multi-tier Application: Example
