JBoss FSW - SwitchYard 先睹為快

因為要參加這次JavaTwo 2013的大會,本來想說隨便拿個講過的東西,再講一次就可以了,可是這樣好像沒有什麼誠意,所以,我就很天才的決定把在國外也還沒有正式發佈的 JBoss SOA 6 拿出來講。讓台灣的大家也可以看到最新的東西,而不是每次都要等米國出了N個月後,才慢慢有人翻譯。

可是真是何苦啊~這樣我就要開始研究這個還沒有正式發表的平台咧~
既然我都研究了,就寫著唄~

(注意,因為所有的內容都是非正式版的,所以跟之後的正式版一定會有出入,目前測試結果,Eclipse 整合上還有些問題,所以還會有一些莫名其妙的小bug~ )

SOA 6 裡面分成三大塊元件,


工具的部分,包含JBoss Developer Studio 的開發工具plugin, 還有本身結合JUnit 的測試工具,可以用來測試SOA的單個元件。

SwitchYard 是 SOA 主要設計,執行的平台,簡單來說,就是個ESB (Enterprise Service Bus 企業服務匯流排). 裡面還結合了Apache Camel 來做規則的routing(路由),與整合引擎。

負載監控,監控不只是Runtime在跑的時候的,還有設計時候的版本監控等。

SwitchYard 的畫面,

Composite(組合) - 定義單一一個應用程式的界限 。就是上圖最大塊的藍色部分,每一大塊組合就是一個單一的應用程式。

Component(元件) - 放置應用程式邏輯的容器。


Implementation(實作) - 把 智慧邏輯/行動邏輯 加到元件裡,裡面可以用很多不同的應用,例如說Java的程式,如果是Routing 的部分可以用Camel 去做,Camel 可以用java 或xml 的方式。 也可以直接呼叫 JBPM 跟 Drools 的 rule. (甚至可以幫你管理Knowledgebase),也可以是Web Service的 BPEL 呼叫 

Component Service(元件服務) - 將元件實作的服務內容揭露給其他應用程式裡面的服務使用,通常都會在component(元件) 裡面左邊的綠色小箭頭。



Composite Service(組合服務)- 是由元件服務升級上去的,揭露給應用程式外的其他程式使用



Service Bindings(服務綁定) - 設定外部的consumers如何與應用程式內的服務溝通



Component Reference (元件參照聯結) - 將元件實作的服務內容連接其他服務的設定。通常都會在component(元件) 裡面紫邊的綠色小箭頭。


Composite Reference - 將服務連接到應用程式外的連接設定


下次來講如何建立第一個SOA 的 Project吧!

Red Hat JBoss Fuse - Getting Started with Fuse Integration Service 2.0 Tech preview

I just realized that I did not do a getting started for Fuse Integration Service 2.0 Tech preview before I did the pipeline demo, thanks for those of you who reminded me! :)

To get started with FIS 2.0, for people who has just getting to know the technology, here is how I interpret it. Basically, it's divide into two aspect,

1. Integration development, FIS uses Apache Camel as the core technology that creates, orchestrate, compose microservices into a super lightweight thin integration layer, and become the API provider and service orchestrator through exposing RESTful or messaging service endpoints. And you can choose to either package and run it with Spring-Boot or Karaf.


2. Application Deployment and Management, FIS takes advantages of OpenShift platform, and allows you to separately deploy the micro-integration service among distributed environment, at the same time takes care of the failover, high availability, load balancing and service lookup problem for you.


So, now we know …

Red Hat JBoss Fuse/A-MQ - Fuse and A-MQ Version 6.3 GA is released!

Fuse and A-MQ 6.3 GA has just went out. Maybe, you would think this is just only a minor version release why should I care? Hold your thoughts on that! Because they have done a lot of improvements and also added many new features into this release.

Besides various bug fixes and making sure Fuse Fabric is much more stable. There are two major change in this version update:

New Tooling in JBoss Developer Studio (JBDS) 9.1 GA. Newer Apache Camel version – Camel v2.17. I was really impressed by the work put in to make developing Camel application much simpler. First is the installation of tooling itself. Now it has a all-in-one installer so you don't need to worry about which plugins you need to check. See the videos below to see the new "Getting Started" of Fuse 6.3.



And If you notice from the above video, the presentation of camel route in JBDS has also updated. It fixed some of the miss representation of logic and making it easier to read.

Old Camel Route
New Camel Route

Fuse Integration Service - Setup JBDS and create first quickstart application

Before we go and start creating our first application, I want to show you how to setup your JBoss Developer Studio, create a small application from the quickstart example and then running it on Fuse Integration Service.

I am using JBoss Developer Studio version 9, you can find it here.
After download the

jboss-devstudio-9.0.0.GA-installer-eap.jar
double-click it, and start installing with default values.

After successful installation, we will need install the plugins for Fuse, on JBoss Central view, select software update, select enable early access.


And select JBoss Fuse Development for the plugin,


Click on install, and we are all set to go!

First thing first, we want to create a Fuse project to deploy on the base of Fuse Integration Service, which is OpenShift. If you have not installed it, please go back to my previous post for instructions. So on your JBDS, right click and start creating the project. Select new, maven project, if you have installed the plugin correctly, you should …
