As we discussed in Chapter 8, many applications or parts of applications have the opportunity to solve their problems asynchronously. Application integration models that are broadcast based or where there's a natural one-way dataflow between applications are just two examples of when an asynchronous solution can be appropriate. Although we've spent a lot of time discussing performance and scalability for interactive Web applications, it's also important to understand how these measures apply to asynchronous systems. In this chapter, then, we'll focus exclusively on building solutions the J2EE way, that is, asynchronous with the Java Message Service.
