Using RESTful Web Services in Oracle Application Express(APEX) Intro

 Using RESTful Web Services in Oracle Application Express(APEX)  Intro

We will covers creating a RESTful Web Service declaratively using Oracle Application Express's SQL Workshop tool to connect to a database table, and then consuming this service by creating an application and adding a Web Service reference to the RESTful Web Service. 

A client java program is then created and executed that will consume the RESTful Web Service to return data stored in an APEX database table to the java application.

Web Services enable applications to interact with one another over the web in a platform-neutral, language independent environment. 

In a typical Web Services scenario, a business application sends a request to a service at a given URL by using the HTTP protocol. 

The service receives the request, processes it, and returns a response.

Once you have defined a RESTful Web Service, you can call it with a unique Uniform Resource Identifier (URI).

 The Web Service uses the URI to call methods such as GET, POST, PUT, and DELETE.
