I have an extensive knowledge of PHP and MySQL, and I have developed several web applications using these technologies.
Now I want to migrate to Java – based web development.
I also have an extensive knowledge of Object Oriented Programming paradigm.
I want to learn to develop web applications in Java. Where do I start?
