overview
Overview
  • Historically Eclipse is a Java IDE
  • Eclipse Web Tools Platform (WTP) project
    • formally launched in June 2004
    • Extends the Eclipse Platform with tools and APIs for Web and J2EE application development
  • WTP has two subprojects:
    • Web Standard Tools (WST)
    • J2EE Standard Tools (JST)
  • Includes tools for HTML, XML, Web Services, J2EE, Data
  • Includes Server tools for integrating application servers, e.g. Tomcat, Geronimo, JBoss, WebSphere, WebLogic

wtp support and collaboration
WTP Support and Collaboration
  • WTP has support of companies, organizations, academia
    • BEA, IBM, Oracle, JBoss, ObjectWeb, UBC, UofT
  • WTP collaborates with other open projects and standards bodies
    • Apache, W3C, WS-I
  • In fact, the WS-I Java test tools are developed by WTP

the web and j2ee tools
The Web and J2EE Tools
  • There are several different types of development tools for Web and J2EE development
  • Relational Database
  • XML
  • Web Services
  • Server
  • J2EE

Eclipse Foundation - www.eclipse.org

relational database tools
Relational Database Tools
  • Connection Wizard
    • Easily create live connections to a database server using a JDBC driver
  • Multi-vendor support
    • Apache Derby
    • MySQL
    • DB2

Eclipse Foundation - www.eclipse.org

relational database tools1
Relational Database Tools
  • Server Explorer
    • view database elements including tables, views, stored procedures, and user-defined functions.
    • Supports both Live and Offline modes
  • Dependency constraints indicated
  • Browse Data directly from the tables

Eclipse Foundation - www.eclipse.org

relational database tools2
Relational Database Tools
  • SQL Scrapbook
    • A SQL utility/editor which can be used to test SQL commands to be executed to a connected server in the Server Explorer.

    • Assisted editing of XML content
    • Constraints enforced
    • Concise overview of documents

Eclipse Foundation - www.eclipse.org

xml tools1
XML Tools
  • XML Catalog
    • Customize XML resource resolution
    • Based on OAGIS XML Catalog standard
    • Add DTD, XSD, or any XML resource (WSDL, XSL, etc.)

Eclipse Foundation - www.eclipse.org

web service tools
Web Service Tools
  • Graphical WSDL/XSD Editor
    • Edit your WSDL file without wrestling with the syntax
    • Visual overview of Web service

Eclipse Foundation - www.eclipse.org

web service tools1
Web Service Tools
  • XML Schema, WSDL, and WS-I validators
    • Ensure your documents conform to standards (WSDL, XSD) and standard extensions (WS-I)

Eclipse Foundation - www.eclipse.org

web service tools2
Web Service Tools
  • WS-I Test Tools integration in the Eclipse Web Tools
    • Preference for setting the WS-I conformance level

Eclipse Foundation - www.eclipse.org

web service tools3
Web Service Tools
  • Wizard to create Web service top-down (from WSDL) and bottom-up (from Java).
  • Wizard creates a Java stub that binds to a Web service.
  • Wizard can optionally configure test client and deployment of your Web service

Eclipse Foundation - www.eclipse.org

web service tools4
Web Service Tools
