This book primarily targets IT professionals in the field of SOA and Integration solutionsa”in other words, intermediate to advanced users. You are likely to find the book useful if you fall into any of the following categories: A programmer, designer, or architect in Java who wants to learn and code in JBI or ESB. A programmer, designer, or architect who doesnt normally code in Java can still benefit from this book, since we assemble integration components using XML with little to no Java code. An IT Manager or an Officer who knows well about SOA or SOI but want to see something in code (you can adorn your flashy presentations with some live code too).
