Few questions for Ray

Hi Ray,
I have a few questions -
1. I don't have any prior experiance of web services. How would this book help to be comfortable with web services? I mean, for a beginner like me, would the book be easy to digest?
2. The only time i had interaction with web services was when i was asked write a web service wrapper on top of an ejb (one seesion facade and a few entity beans) using a special weblogic ant task. That did not help me to understand web services? My basic confusion was are you supposed to write a web service over an EJB or it can talk to any distratibuted component? this question may sound very dumb, but i really want to know?
3. I heard that sun is coing up with web services certification? do you have any idea abt that?
4. Is this book available in india?
5. I dont know your back ground yet, i mean u must be having a solid one to write a book on such upcoming technology. but I really want to know abt your technical experiance, what made u write this book etc.
Thanks in advance.

The book is not for beginner. The author has mentioned this in one of threads.

True.Evelyn has posted a thread regarding this in the forum.

I got some postive feedback from both management and techies. The book looks readable even for those who have no background in web services. So, give yourself a try.

2. The only time i had interaction with web services was when i was asked write a web service wrapper on top of an ejb (one seesion facade and a few entity beans) using a special weblogic ant task. That did not help me to understand web services? My basic confusion was are you supposed to write a web service over an EJB or it can talk to any distratibuted component? this question may sound very dumb, but i really want to know?

Earlier books on web services suggest using a utility (e.g. Axis's java2wsdl) to expose a servlet, Java bean, EJB or C++ function as RPC-style web services. This is only one style, 'cos you can write asynchronous doc-style web services by using messaging (e.g. SAAJ or JAXM). This will be a completely different paradigm than your weblogic EJB web services experience.
perhaps it's useful for you to go back to the basics of what makes web services, and how they can be created (doc or RPC-style). Have a feel of the samples in Axis or JWSDP to experience how to create a simple web service. For example, my book ch 9 section 9.4 has a simple Axis step-by-step tutorial, and ch 3 section 3.8.4 has a simple JWSDP step-by-step tutorial.

3. I heard that sun is coing up with web services certification? do you have any idea abt that?

Yes, the team will meet in April, probably the second time, to create the exam questions.

4. Is this book available in india?

You can order via Amazon, barnes and nobles, bookpool.com or your local store.

5. I dont know your back ground yet, i mean u must be having a solid one to write a book on such upcoming technology. but I really want to know abt your technical experiance, what made u write this book etc.

I have >15 years working experience, particularly in financial services, transportation. My last 5 years are focused in Java-based technology. I started to build up my working experience in hands-on web servcies architecture and simple Proof of concept experience in my consulting work. After I've done a few cases, then I start to write this book, and verify it with my customer consulting. I believe real experience counts, not pure research.
