We've updated the WAS recommended reading list and created a new one for WBPM.
The updated one is the J2EE and WebSphere Application Server Recommended Reading List. Like the title says, it focuses on articles and other stuff for learning about J2EE and IBM's J2EE products like WAS and RAD. I've talked about it in the past in ISSW Recommended Reading List Updated.
We now also have a completely new list, the Service-Oriented Architecture and WebSphere Process Server Recommended Reading List. Like the original, this one focuses on technology and products. The technology is SOA and ESB; the products are the WebSphere Business Process Management products, especially WPS and WID.
These lists are produced by my department, IBM Software Services for WebSphere. In fact, I had a hand in producing both lists. We hope you find them helpful.
