In the previous chapters you've seen a little about the promise of using Web Services in WebSphere. In this chapter we'll cover some of the architectural challenges posed by Web services, examine how to use (and not to use) Web services, and see some best practices in applying Web services for solving tough architectural problems.
Web services are the final piece of our architectural road map. You will see in this chapter (as you have seen as the previous chapters on Web services) how Web services in WebSphere usually use stateless session beans as their component implementation. The position of Web services in our road map is shown in Figure 34.1.
