Hi all, I got a job in Bangalore even though it's recession time. They have said my project will involve Java, Ruby on Rails, Ajax and they also said Web Services (which i have always wanted to try) and some stuff I have not much exposure like REST, mashups and Struts. Can anyone tell me if there are some good training or conferences to get to speed with these technologies. I need to do really good in my job. Thanks, Vaibhavi
