- Preface
- 1. Creating a basic OSB service
- Introduction
- Creating a new OSB project
- 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
- Introduction
- Setting up an OSB project to work with JCA adapters
- Using context menu to add nodes and actions to message flow
- Moving nodes/actions in Eclipse OEPE by drag-and-drop
- Copying nodes/actions from one place to another
- Moving artifacts inside the same OSB project
- Copying artifacts from one project into another
- Debugging services through 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 request-response messaging with JMS
- Using QBrowser Admin GUI for accessing JMS queues/topics
- Testing JMS with soapUI
- 4. Using EJB and JEJB transport
- Introduction
- Exposing an EJB session bean as a service on the OSB using the EJB transport
- Using JNDI Provider to invoke an EJB session bean on a remote WebLogic domain
- Using converter class with EJB transport to help converting data types
- Exposing an EJB session bean as an EJB on the OSB using the JEJB transport
- Manipulating the response of the JEJB transport by a Java Callout action
- 5. Using HTTP Transport
- 6. Using File and Email Transports
- 7. Communicating with the Database
- Introduction
- Using DB adapter to read from a database table
- Using DB adapter to execute a custom SQL statement against the database
- Using the DB adapter to update a database table
- Using DB adapter to poll for changes on a database table
- Using the AQ adapter to consume messages from the database
- Using the AQ adapter to send messages to the database
- 8. Communicating with SOA Suite
- 9. Communication, Flow Control, and Message Processing
- Introduction
- Using Service Callout action to invoke a service
- Using the Publish action to asynchronously invoke a service
- Using the Java Callout action to invoke Java code
- Using the Java Callout action with XMLBeans
- Using custom XPath functions
- Using the For Each action to process a collection
- Using dynamic Split-Join to perform work in parallel
- Using the Validate action to perform message validation
- Enabling/disabling a Validate action dynamically
- 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 the Service Callout action to invoke a service
- Using the Publish action to asynchronously invoke a service
- Using the Java Callout action to invoke Java code
- Using the Java Callout action with XMLBeans
- Using custom XPath functions
- Using the For Each action to process a collection
- Using dynamic Split-Join to perform work in parallel
- Using the Validate action to perform message validation
- Enabling/disabling a Validate action dynamically
- Creating private proxy service
In this chapter, we will show how to use different actions from the Communication, Flow Control, and Message Processing section of the OSB Design Palette.
We will show the various options to invoke other logic, such as Service Callout, Publish, and the Java Callout action as well as the ability to create custom XPath functions. Another topic covered is the processing of collections either through a loop sequentially or by a Split-Join in parallel. The validation of messages and the creation of private proxy services are also covered in this chapter.
