Web services provide us with a means to attain SOA-based architectures. With the growing number of technology frameworks available today, it is easy to deploy web services.

XFire is a SOAP stack with which we can quickly and easily expose web services. As seen in this chapter, a combination of technology stacks like XFire and Spring can help to bind external services, including external EJB services. Once bound, these services can be re-published as web services so that they become firewall friendly. This is similar to JBI binding of services providing a mediation layer for service integration, more of which we will see in later chapters.

We now have had enough of traditional bindings and bindings using XFire. With this background it is time now to delve deep into JBI and related services. We will continue with more JBI discussions in the next chapter by understanding the JBI packaging and deployment model.
