Do you feel like the quality of assistance you receive from a vendor support line might determine whether you still have a job at the end of the day? I know I am not alone in these worries, because at WebSphere ® User Group conferences I often get asked how things work—sometimes even by vendor sup- port staff! Some time ago, I decided to look into how WAS works under the covers and document it at a level that would help me and the user community. I also wanted to document some unorthodox techniques that help in problem deter- mination for those of us that don’t have access to the source code. For WAS 7, the result is Pro IBM ® WebSphere ® Application Server 7 Internals. In this book, I present WAS 7 from the bottom up so that you can learn what makes it tick. I explain how the IBM ® version of the JVM works; how the Eclipse and OSGi ™ component and service models provide a base for an enterprise- class application server; and how the Java EE–level container structures and interactions function. I also look at how IBM extends WAS, and give code sam- ples that explain how WAS works and help you to build your own tools to look under the hood. My friends inside IBM have always been supportive, but they can’t tell me their trade secrets. Nevertheless, I’m convinced the secrets I’ve discovered on my own by looking from the outside in will be useful to you as presented in this book. The knowledge of what goes on under the covers will make you better at your job and, hopefully, help you sleep better at night. Enjoy the exploration.
