- Defining a folder structure for the OSB project
- Importing an already existing project into Eclipse OEPE
- Creating a business service to call an external SOAP-based web service
- Generating a simple pass-through proxy service
- Deploying the OSB configuration from Eclipse OEPE
- Testing the proxy service through the OSB console
- Testing the proxy service through soapUI
- Creating proxy service with a WSDL based interface
- Using a routing action to statically route to another service
- Adding an operational branch to support the different WSDL operations of the proxy service
- Using an XQuery transformation to map between the different data models of the services
- 2. Working Efficiently with OSB Artifacts in Eclipse OEPE

- 3. Messaging with JMS Transport
- Introduction
- Sending a message to a JMS queue/topic
- Changing JMS Transport message headers and properties at runtime
- Consuming messages from a JMS queue
- Consuming messages from a topic with non-durable/durable subscription
- Consuming messages from a JMS queue/topic selectively
- Accessing JMS Transport headers and properties in message flow

- Using QBrowser Admin GUI for accessing JMS queues/topics
- Testing JMS with soapUI
- 4. Using EJB and JEJB transport
- Introduction

- Creating private proxy service
- 10. Reliable Communication with the OSB
- 11. Handling Message-level Security Requirements
- Introduction
- Preparing OSB server to work with OWSM
- Configuring OSB server for OWSM
- Securing a proxy service by Username Token authentication
- Securing a proxy service by protecting the message
- Securing a proxy service by using Username Token authentication and protecting the message
- Securing a proxy service by using certificate authentication and protecting the message
- Securing a proxy service with authorization through Message Access Control
- Using JDeveloper to test a secured service
- Calling a secured service from OSB
- 12. Handling Transport-level Security Requirements
- Index
In this chapter, we will cover:
- Using HTTP transport to implement messaging over HTTP
- Exposing a RESTful service on the OSB
- Consuming a RESTful service from the OSB
- Creating a generic RESTful gateway on the OSB
- Implementing a WebSocket transport for server-side push
In this chapter, we will cover the HTTP transport.
The HTTP transport allows sending messages between clients and service providers through Oracle Service Bus using the http(s) protocol. The HTTP transport also provides support for working with RESTful (REST = Representational State Transfer) services.
The HTTP transport can be used on the proxy service to accept inbound messages over the HTTP protocol as well as on the business service to implement outbound communication over HTTP.
We have already used the HTTP transport when implementing the SOAP-based service in Chapter 1, Creating a basic OSB service. In this chapter, we will present how to work with the HTTP transport without using SOAP.
