Deploy using the JVM's high performance while building your apps in the language you love. JRuby is a fast, scalable, and powerful JVM language with all the benefits of a traditional Ruby environment. See how to consolidate the many moving parts of an MRI-based Ruby deployment onto a single JVM process. You'll learn how to port a Rails application to JRuby, get it into production, and keep it running.JRuby deployments have fewer moving parts and consume less memory than traditional Ruby deployments, but to deploy your apps on the JVM, you need to learn some new approaches. This book introduces you to three JRuby deployment strategies that will give you the performance and scalability you need while letting you use the language you love.You'll start by porting an existing application to JRuby, preparing the app to take advantage of the JVM platform. Then you'll use Vagrant and Puppet to build a virtual production environment so you have a stable, reproducible place to explore JRuby deployment. With your environment in place, you'll experiment with simple JRuby deployment with Warbler as you package your Ruby web application into a single file you can deploy to a Java application server. Next you'll set up the lightweight Trinidad web server to create a more flexible, modular deployment that fits more complex situations but still feels friendly and familiar to Ruby developers. You'll switch to powering your app with TorqueBox, an all-in-one JRuby environment that includes built-in support for messaging, scheduling, and daemons--perfect for handling the "big jobs." Then, you'll set up a continuous integration environment with Jenkins so you can deploy like the pros.Deploying with JRuby is the missing link between enjoying JRuby and using it in the real world to build high-performance, scalable applications.What You Need:To run the examples in this book, you'll need a computer that can run the Java Virtual Machine.

自從Oracle接手Java的發展之後，Java開始了天翻地覆的變化，加入了許多新功能，這些新功能都是為了跟上最新流行的程式語言與新型態的發布、維護架構。其中最重要的就是SE8的Lambda運算式與SE9的模組（module）。 自SE9開始，Oracle就採取敏捷開發的精神，每半年就發布一個新版本，不過這些大多是非長期支援版本，新版本一旦發布，舊的非長期支援版本就無法下載JDK了。所以開發與學習的首選通常以長期支援版本為主。依據Oracle的規劃，長期支援版本會在三年左右的時間發布，其中，SE11及SE17都是長期支援版本（LTS），本書的改版政策也跟隨此政策，只會推出適用於長期支援版本的書籍。 Java的新功能眾多，如何將這些新功能完美融入原有功能的講解是本書的重點，例如本書將Lambda運算式放在第十五章，讓讀者可以於學習過內部匿名類別後才學習如何利用Lambda運算式來取代內部匿名類別，並應用於視窗程式（事件傾聽處理）。本書將模組（module）放在第十一章的類別庫（package）之後，讓讀者理解如何透過模組來保護類別庫。至於SE10新增的小功能：var型態推斷宣告更是被不露痕跡地加入到第三章與第十五章，因為在SE11時，var型態推斷宣告已經被推廣至Lambda運算式，免除了程式設計師為了回傳值型態還需查閱手冊的麻煩。 本書改版自暢銷數萬本的《初學指引》系列，從SE8版開始更名為《掌握》系列。這是因為作者認為本書已經不再適用於只想學些皮毛的讀者，而是期望將讀者由初學者導引成為Java初級工程師，要做到這一點，就應該在第一本學習書籍當中，充分掌握Java的設計精隨以及關鍵基礎技術，故重新命名為《掌握》系列。 本書以細心規劃的進度，培養讀者在十六周的學習中，成功變身為Java初級工程師，同時釐清一些對於初學者容易產生困擾的技術。同時本書也搭配精心設計的累積式習題，讓讀者能夠循序漸進地真正成為一位Java程式設計師。 本書的特色如下: ．長支援版 ．內容由淺入深 ．整合模組與類別庫 ．釐清複雜的泛型等語法 ．Java SE7到SE11/17的無縫接軌 ．釐清函數式介面與抽象類別的差異 ．釐清匿名類別與Lambda運算式的適用場合 ．釐清Java只有傳值呼叫，沒有如同C#的傳參考呼叫 ．透過「Coding偷撇步、注意事項」加強讀者的程式設計實務經驗 ．透過「延伸學習」明確引導讀者，未來的學習之路 ．透過「筆者的話」向讀者傳遞正確的基本觀念 ．探討浮點數變數為何不適合做為比較條件 ．探討編譯器為何加入final的this參數? ．探討高鐵為何會重複賣票 ．累積式習題培養功力 ．其他…………
