Hi ALL... Am very new to the world of RoR..am bascially a Java certified professional...am wanting to start of learning RoR...pl guide me to master RoR.. Pl suggest me some online tutorials,websites where we can find the related material.
Start with the Rails Guides and Railscasts. There is a good, free to use online, tutorial at railstutorial.org. Make sure that any tutorial (or book) you use is for Rails 3 (and make sure you install Rails 3). The book Agile Development with Rails is good (again make sure the edition you get is for Rails 3). The Pickaxe book is the one for Ruby.

RoR is web application framework and it assumes that you already know ruby programming language. Before learning RoR I think you want to learn ruby language first. Start here http://www.ruby-lang.org/en/documentation/
You can try this Rails 3 tutorial: Learn rails by example: Ruby on Rails Tutorial | Learn Enough to Be Dangerous
After you finish this tutorial, you will know how wonderful Rails 3 is and know why Java is not get close to it.
Enjoy.
