Introduction

This document is one of a series of tutorials to demonstrate the use of the Web Services tools in the Web Tools Platform Project using a WTP 1.0 driver.

This tutorial shows how to use the Web Service Explorer to test a Web service via native WSDL and SOAP. It demonstrates how to use the Web Services Explorer to invoke operations on a Web service named " Delayed Stock Quote " as available from XMethods on the internet.

The only prerequisite is that you be connected to the internet. If you are connected via a firewall, you can use the Internet preferences page (choose Preferences -> Internet from the main menu). Otherwise, you can begin with a completely fresh workspace and no installed servers.

Using the Web Services Explorer to test a Web service

1) Launch the Eclipse WTP workbench. 2) From the main menu bar, select Run -> Launch the Web Services Explorer. This will take a few moments the first time while Eclipse's internal Tomcat server starts up and loads the Web Services Explorer application. 3) After the Web Browser view opens, maximize it. Result:

4) In the Web Service Explorer's toolbar (top-right), click on the WSDL Page icon
5) Click on the WSDL Main icon. Result:

Editing the schema is achieved by invoking context menu actions on selected objects in the Graph view and using the properties view to modify the properties of the selected object. Go back to the top-level view and follow the steps below to create a new element declaration and define its content.

1. right click on the header of the 'Elements' section of the top level schema and choose 'Add Element'
2. use the properties view to change the name of the element to 'Paper'

4. select 'Complex Type' and check 'Create as anonymous type'. Click 'OK'.
   
   
   
   
5. Double click on 'Paper' to explore this element, note that 'PaperType' is surrounded by parenthesis to indicate anonymity of this type. Click on this type to invoke the properties sheet for its.
