WebSphere Studio Tooling

Developing Web Applications requires more than just

writing Java code

Roles-based Development

Development Environment Goals

Create a new Development Environment that will:

Be based on a new open, highly pluggable platform

Unified by a new tooling platform

Provide multilevel vendor integration

Provide a role-based development model where the assets are the focus, not the tool

Provide a common repository solution for all assets and toolsProvide rapid support for new standards and technologies

For example, Web Services

IBM WebSphere Studio Family

Provide a sturdy Web/Java development platform in the industryOpen tooling and run-time support

Open programming model

Provide in-depth Enterprise connectivity

EJB/J2EE Tooling

Enterprise Connectivity/Enterprise Access Builders

Provide integrated end-to-end development

Built-in Unit Test Environment

Integrated version control

Family Contents

WebSphere Studio Products (V5) :

WebSphere Studio Application Developer (includes all of Site Developer functionality

Focused on development of Web Services, JSPs, Servlets, XML and J2EE and database applications in a team environment

WebSphere Studio Enterprise Developer

Includes all of Application Developer functionality

Focused on Enterprise Integration using the J2EE Connector

Architecture

Supports integrated development of z/OS based CICS, IMS and batch applications

WebSphere Studio Workbench

Workbench is:

Not a tool, not a product, not for sale

A portable, universal tool platform and integration technologyThe basis for an open source project

Workbench has:

Frameworks and services that enable tool builders to focus on tooling building

Tools to help tool builders build tools

Java Development Tools (JDT)

Plug-in Development Environment (PDE)

WebSphere Studio Workbench Rationale

End-users (Web application developers)

No more on-site integration, tools just work together

Common, easy-to-use interface

Common code, project, file management system

Same tool platform regardless of development role

Same look and feel regardless of tool vendor

Tool Builders

Seamless integration and interoperability with IBM AD tools and WebSphere Software Platform

Seamless integration with other Workbench tools

Enterprise ready, off the shelf

Globalization, distributed debug, Team, SCM

Easy construction and deployment platform for tools

Open access to source code and tool provider community

Start the WebSphere Studio Application Developer

Start -> Programs -> IBM WebSphere Studio -> Application Developer 5.1 Workbench opens when you launch Application Developer

Within the workbench open the perspectives, views, and editors

WebSphere Studio Application Developer

Java: to develop and test Java programs

Server: to configure, run, and manage test servers

Debug: to control debug flow, see variables, and so forth

A view displays specialized information For example:

Bookmarks view displays all bookmarks in workbench

A view might appear alone in a single pane, or several views might

be stacked within a single tabbed pane

Views can be undocked/docked from the main workbench window.Information updates on a view are saved immediately

View toolbars apply only to the particular view in which they appear

An editor is used to edit or browse a resource

Modifications made in the editor follow an open-save-close life cycle

An editor can contribute to the Workbench menu bar

Examples:

Java Source Editor

Web Deployment Descriptor Editor

Web Site Configuration Editor

JSP Editor

WSDL Editor
