Web Services

Web Services Development with JDeveloper 10g

– J2EE Web Services, based on Java classes, EJBs, BC4J Modules wrapped as EJBs

– SOAP Web Services, based on Java classes, EJBs, BC4J Modules wrapped as EJBs

– PL/SQL Web Services, based on program units stored in PL/SQL packages in the database

– JMS Web Services, for asynchronous message queuing

Creating the UML Diagram

Generating the Web Service

Generate Stub/Skeleton

Generate Stub/Skeleton

Wizard Components

WSDL Document URL Enter the URL of the Web Service Description that you want to use.

This could be a:

• File that you locate using the Browse button

• HTTP URL

Generate Client Side Stubs– Select this to generate a client-side Java stub for the service

Generate Main method into Stub– The generated Stub will contain a main() so that you can run

stub methods without having to create another class

Generate basic HTTP Authentication code– Select this to generate the outline code for HTTP

Authentication

Wizard Components

Generate basic Proxy Authentication code Select this option to generate proxy code to facilitate

consuming the service through a proxy server

Generate Server Side Skeletons– Select this to generate a server-side skeleton interface from

the WSDL Document

Import WSDL Document into project– Selecting this will add a node to the Navigator of the WSDL

URL– This creates a pointer to the WSDL location so you can

interrogate it by double clicking the node in the Navigator

Wizard Components

Default Package– The default package into which the generated Java classes

for the stubs or skeletons will be generated is displayed. You can either accept the default, or enter your own package name.

– The entry in this field will be ignored when you are generating a stub to a web service created using JDeveloper which uses java beans. In this case the default package name created, when the web service was generated is used

Selecting the method(s)

Run your Web Service
