This year started on a busy note ..It has been some time that I visited my blog for an update ..
Check out this redbook draft on WebSphere Business Services Fabric. Some of the chapters might be very useful in understanding the basic concepts around composite applications.
There are many advanced topics like context propagation, integration with UI components, policy authoring, transaction management etc that are not covered as part of this book. We hope to put these advanced topics in next book ..
Until next time ..ciao ..
