Hi Glen and Peter,
Thankd for sponsoring the book on Java Ranch.

To be fare, I'm new to this Grails and also a freelance developer.
1. Can I learn and develop projects after reading this book?
2. How can this be useful in mobile applications?
3. What is the difference between this and Ruby on Rails?
4. What is the commercial potentiality of this technology?

Palla,

I will try to answer what I can

How can this be useful in mobile applications?


For usage of grails in mobile applications, please see this good article http://www.ibm.com/developerworks/java/library/j-grails06178/index.html

What is the difference between this and Ruby on Rails?



Grails and Rails have similar philosophy. However, Groovy has easier learning curve for Java developers. Hence it makes Grails a natural choice for you if you are coming from a Java background.

4. What is the commercial potentiality of this technology?


People are beginning to use Groovy in Java projects for smaller tasks such as Unit testing. Groovy is not yet the main language on large scale projects where Java is more dominant. However, you will be able to find many examples of Groovy and Grails usage in smaller/medium applications. As far as the job market goes, it is unlikely that you will get your next job/assignment solely due to your knowledge of Groovy/Grails
