  9. WebSphere Application Server 6.0

  10. WebSphere App Server - Version 6.0 Key Features and Functions • Continuing support of open standards • J2EE 1.4, JDK 1.4 • Continued enhancements for the latest web services standards • EJB 2.1 • Servlet 2.4 • JSP 2.0 • Java Authorization Contract for Containers • J2EE Management 1.0 • J2EE Deployment 1.1 • J2EE Connectors 1.5 • Java Server Faces • JSR 168 (Portlet) • Extending support for the e-business on demand operating environment • Enhanced autonomic/grid support • OGSA standards support • Emerging OS support – 64 bit • AIX, HP-UX, Linux, Solaris

  11. WebSphere Express • Full Programming Model • J2EE 1.4 Certified Runtime • Web Services • Programming Model Extensions • Single Server Model (no clustering, no multi-server management) • Includes Tooling (WSSD)

  12. WebSphere for Network Deployment • This is the clustered, multi-machine solution • Deployment Manager • Includes optional samples and applications that can be installed into servers in the cell • Contains a set of production optimized templates for new server creation • ND Runtime • Optimized for production environments • Only contains the content needed on the production machine • No Samples • No Javadoc • No Admin Console • Can be federated to the Deployment Mgr during product install • Contains no default configuration (other than the definition of the node itself)

  13. J2EE 1.4 • Many changes, primarily focused on Web Services • Added several new APIs • JAX-RPC • SAAJ • WSEE (JSR 109) • JAXR • JMX • J2EE Management (JSR 77) & Deployment (JSR 88) • J2EE Authorization Contract (JSR 115) • Many updated APIs as well • EJB 2.1 • Servlet 2.4 • JSP 2.0 • Added Expression Language (JSP-EL) • .tag/.tagx File support • Improved XML Syntax (.jspx/.tagx) • API for EL • JCA 1.5 • In bound connector support • JMS 1.1 • XSD-based Deployment Descriptors

  14. Web Services - Other • JAX-RPC Multi-protocol support • Including EJB Bindings for higher QOS • Optimized Parsing Support • HTTP 1.1 Support • Performance boost with keep-alives • Systems Management Improvements • Server startup optimizations including deferral of processing • WebSphere Rapid Deployment Support • Extended SOAP Element support • Lazy parsing • Optimized retrieval APIs to leverage lazy parsing • Improved Support for existing EJBs • JService support • Enterprise Service Bus support • Custom Serialization • Support for overriding the serialization technology stack of the middleware for element types

  15. Programming Model Extensions • Due to WAS-E becoming WBI Foundation, most of the PMEs that were in WAS-E are now moving into WAS Express or WAS ND. • Moving to WAS Express • Last Participant Support • Internationalization Service • WorkArea Service • ActivitySession Service • Extended JTA Support • Startup Beans • Asynchronous Beans (now called WorkManager) • Scheduler Service (now called Timer Service) • Object Pools • Dynamic Query • WSGW Filter Programming Model (with migration support) • Distributed Map • Application Profiling • Moving to WAS ND • Back-up Cluster Support

  16. Data Access APIs Data APIs Data APIs Data APIs Data APIs Client Mediator Meta-Data Access APIs Meta-Data APIs Service Data Objects • The Problem • Many different models and APIs for Data retrieval, Data representations, Meta-data retrieval, Meta-data representations, logic components • No reasonable API available for “typed” XML data • Lack of support for standard application patterns • Optimistic concurrency, pagination of large data-sets, etc. Data Access APIs Data Access APIs Data APIs Data APIs Data APIs Data APIs Client Data Access APIs Meta-Data Access APIs Meta-Data APIs

  17. Data Access APIs Meta-data model (ECore) Client Data APIs Pluggable Data Mediator Meta-Data Access APIs Data model (DataObject) Meta-Data APIs Service Data Objects • SDO DataObject with XSD & EMF provide a single, standard API (& implementation) for data & meta-data that we can use in place of many other APIs • Data is stored in a disconnected, source-independent format defined by the DataObject • DataObjects are stored in a graph called a DataGraph • Provides both dynamic loosely-typed and static strongly-typed interfaces to the data • Remembers change history • Data Mediator Service is responsible for filling graph of DataObjects from data source, updating data source from DataObject changes

  18. JMS Support • WAS V6 will provide a pure Java JMS 1.1 provider that can be installed as part of the base server installation (not a silent install of another product with its owns prereqs) & run completely inside the application server JVM. • Supports embedded Cloudscape for persistent messages, in additional to DB2, Oracle, etc. • No separate messaging server process (all contained in the app server) • Fully integrated with the application server (Systems Management, RAS, Security, PMI, Threads, IOManager, etc) • Each server can have its own, interconnected messaging engine • Interoperable with MQ

  19. WebSphere Rapid Deployment - The Goal • To simplify the development experience for WebSphere applications by: • Reducing the number of artifacts the developer must produce and maintain • Reducing the number of concepts and technologies the developer must understand • Supporting the development model and tools the developer desires to use • To simplify the deployment experience for WebSphere applications by: • Automating the process of installing an application on WebSphere • Reducing the amount of information that must be collected by the installer to install the application • Automating the process of activating incremental changes to an application on a running server

  20. WRD Focus Areas • Annotation-based Programming • Allow the developer to insert metadata into the source code of the application • Use the metadata to generate the additional artifacts required by the runtime that the developer does not need to be confronted with • Allow the developer to create and maintain a single artifact • Change Triggered Processing • Drive processing operations based on the change detection of application artifacts • Used to generate new application artifacts from existing artifacts • Used to drive deployment operations • Enables a “Hot Directory” concept for “file copy” and “Notepad” development and deployment • Deployment Automation • Enable automatic install of applications & modules onto running WebSphere Server • Support both local and remote servers • Support fine-grained application changes • Support the concept of minimal application impact (affect the application in the minimum way possible to reflect the detected change)

  21. WRD Annotations Example • package com.example.wrd; • /** • * @ejb.bean name="Hello" type="Stateless" view-type=remote jndi-name="HelloBean" • */ • public class Hello { • /** • * @ejb.interface-method view-type=remote • */ • public String hello(String name) { • return "Hello: " + name; • } • }

  22. Java Server Faces • Emerging Standards based Web Application Framework • Plug-and-play other JSF components easily • Targeted for Web Application Developers with little Java background • Competitive technology against Visual Studio .Net WebForms, & WebLogic Workbench • Based on MVC design pattern • UI components are decoupled from its rendering • Allows for other technology (e.g. WML, etc) to be used • Event driven architecture • Server-Side Rich UI components respond to client events • Simplifies development of Web Applications • Eliminates much of the hand-coding involved with integrating back-end systems • WebSphere Studio 5.1.1 is the first IDE to support JSF based web application development

  23. Summary • WebSphere is evolving rapidly to track the latest industry specifications & standards • J2EE 1.4 • Web Services • WebSphere is adapting to the latest industry trends • Merging of Application Servers and Messaging Technology
