Conclusion

This chapter began with a description of Web service fundamentals. It described the

underlying flow of a typical Web service on the Java platform, showing how the

various components making up clients and services pass requests and responses

among themselves. The chapter also described some example scenarios, which it

used to illustrate various concepts. Once the groundwork was set, the chapter dis 

cussed the key design decisions that a Web service developer needs to make, princi 

pally the design of a service as an interaction and a processing layer. It traced how to

go about making design decisions and recommending good design choices for spe 

cific scenarios. 

The next chapter focuses on developing Web service clients.
