6. Play Framework
Makes it easy to build web applications with Java and Scala.
Is based on a lightweight, stateless, web-friendly architecture.
Built on Akka, provides predictable and minimal resources consumption (CPU, memory, threads) for
highly-scalable applications.

11. Is Reactive

12. MVC Architecture

13. App Server
Since Version 2.6.x
Fewer Configurations

14. JRebel Behavior
More code, Less deploys

15. How start a Play project?
We need to use SBT Create sbt new playframework/play-scala-seed.g8 sbt new playframework/play-java-seed.g8 Deploy sbt run

16. $ sudo sbt new playframework/play-java-seed.g8
This template generates a Play Java project
name [play-java-seed]: OracleCodeSydney
organization [com.example]: com.produactivity
scala_version [2.12.2]:
play_version [2.6.1]:
Template applied in ./oraclecodesydney $

17. $ cd oraclecodesydney/
Oraclecodesydney $ sbt run

Allows communication between a client and a server
Provide a standard means of interoperating between different software apps
Characterized for interoperability and extensibility
Based on XML

31. SOAP Simple Object Access Protocol XML-based
Use WSDL as specification description
(Web Services Description Language)
Need to follow a communication protocol

33. Restful Software Architecture based on HTTP methods
(Get, Post, Put, Delete, etc)
Typically use JSON, but can use XML, Text
