- B. Pop-quiz Answers
- Index
In this chapter we have looked at most of the bus providers available for delivering ESB messages to target services, focusing primarily on the InVM transport and its capabilities.
Having followed through this chapter you should now have a good understanding of:
- How to use a file system provider
- The InVM provider
- The difference between pass-by-value and pass-by-reference
- When to use the lock-step delivery mechanism
- How threading affects the InVM transport
- How the InVM transport works within a transactional context
- Which provider to choose based on transactional needs
We also revisited the JMS provider, used in many examples throughout this book, and introduced the configuration for the SQL and FTP providers.
Now that we've learned how to deliver messages to ESB services, let us look at how external systems and transports can be integrated with JBoss ESB through the use of gateways—the topic of the next chapter.
