Best approach for learning Java for web development as a programmer

I am looking to learn Java for the purpose of web development. I am a talented programmer with background in windows programming, C# and PHP. I don't need to be explained OOP or anything I would consider to be basic programming knowledge. I'm not sure if I should start at the command line and learn the whole language or if I can jump in head first into web development and learn that way.

Just figured I'd ask around in case someone could suggest me the right book or something
Thanks!

If you are a well experienced with development on different languages and platform, you should start with the advance stuff. The core is quite same on all the way, but the syntax and semantics have slight different and that only you have to learn.
