Hi Vaibhavi,
There are several online resources available that you just google for. If any of your team like to read then quality books from wiley and oreilly cover such technologies in detail.
I also highly recommend you could attend the upcoming Great Indian Developer Summit (
http://www.developersummit.com) that is covering Java, Agile, REST, JAX-RS, mashups, .NET, Rich Web, JPA, SOA, rich user experiences, Spring, Groovy and more. They have most of the creators of these technologies as speakers. My team is attending this summit 22-25 apr at IISc campus where we are attending the web conference on April 23 and java on April 24. We have been able to get very good discounts. Maybe all those who are interested from your group can sign up together and get a good bargain from them. what say? I also attended last year's conference and had a really cool time.
In Hyderabad there is Sun Tech Days with some sun speakers.
Thanks,
Anaz
