Similar to this question http://stackoverflow.com/questions/72719/good-book-for-a-c-developer-going-over-to-java I'd like to know what books mainly targeting web development people would recommend.
I'm currently developing large applications with ASP.NET MVC using TDD/DDD (persistence provided by NHibernate, IoC/Application Framework by Castle), so anything that might build on that would be really appreciated.
I found Thinking in Java to be a useful guide. And you can download earlier editions (still very useful) for free.
Given your previous experience I wouldn't recommend any entry-level books.
You might enjoy "Agile Java Development with Spring, Hibernate and Eclipse" - this introduces Java versions of the tools you are familiar with.
For more detailed info the 'X in Action' books from Manning are very good, not least because you can buy the PDF versions and dip in and out as required.
