A developer's notes about upgrading to Java EE 8

Java EE 8 brings a plenty of new features which are valuable to build modern applications.

I have spent some time on updating myself to the newest Java EE 8 technology stack. This mini book is my learning notes when I refreshed my knowledge to Java EE 8. It will not cover the existing content in Java EE 7. If you are new to Java EE or need a comprehensive guide of Java EE, I suggest you read the official Java EE Tutorial carefully.

This mini book will cover JSF 2.3, CDI 2.0, JSON-B, Java EE Secuirty API 1.0, Servlet 4.0, JAX-RS 2.1 etc.
