JBoss BRMS - 在Open Shift 上安裝BRMS

前幾個禮拜跟朋友去聚會,因為大家都是一堆IT宅,不可避免地聊著聊著,就聊到大家的公司,最近在做些什麼... 出乎意料之外的,發現大家對雲端的Paas 都很有興趣哩~
還有的朋友把程式也放到雅馬遜的EC2 上。。 其實,EC2 的底層也有JBoss 呢!

========================================
=====vvv在安裝之前,請先確定以下都安裝好了vvv=====
========================================
1.到 OpenShift 註冊一個帳號
(這個因為只是普通的註冊,就不多說了。。。)

2. 在電腦裡面安裝 rhc的執行指令

(等我以後有空再寫,其實不難,請到官網上看...)
========================================

因為OpenShift 上面跑的應用程式平台是JBoss EAP 6, 這間接證明了一件事,哈,那就是,BRMS 是可以跑在 JEAP 6 上的喔!
好,廢話不多說,

1. 建立一個Application (應用程式)

rhc app create -a brms53 -t jbosseap-6.0


2. 把eric 提供的程式碼放到Open Shift幫你自動建立的 github repo 裡面

3. 把程式放到server中

以一般JBoss 的安裝思維,這樣應該就裝好了... 但是... 世界當然沒有這麼美好,因為畢竟是Openshift, 所以還是要有一些單獨調整的設定,但是希望總有一天可以接自動化就安裝好了...

設定筆記

這個Project要感謝 Kaushik Bhattacharya,大家有空可以去他的專案總部大聲說謝謝捏: https://github.com/kbhattac/brms53

1) 設定jboss-brms 裡面的 jackrabbit repo, 在jboss-brms.war 中的 components.xml。所以要先找到你自己的UUID,方法如下


rhc app show -a brms5.3



找到後,請將UUID 寫在你的components.xml裡面。





2) 到 designer.war 裡面的 profiles/jbpm.xml 修改host 的 ip 位置,請ssh 進去,跑cmd 模式執行 export $OPENSHIFT_INTERNAL_IP 去找到你的IP 然後放到XML裡面。



3)因為記憶體有限,有的時候,同時部署jboss-brms.war 跟 designer.war 會失敗,所以,我們讓jboss-brms.war 先自動部署。等jboss-brms.war 部署完畢後,我們再把designer.war.dodeploy.delayed 重新命成designer.war.dodeploy,這樣就會自動觸發系統重新部署了。

$ ssh [UUID]@brms53-$your_domain.rhcloud.com
$ mv brms53/jbosseap-6.0/standalone/deployments/designer.war.dodeploy.delayed  /
     brms53/jbosseap-6.0/standalone/deployments/designer.war.dodeploy

如果要看designer.war部署的狀況,可以用以下方式看log

$ rhc-tail-files -a brms53

成功之後你就可以到下列網址看到你的BRMS了! 

http://brms53-$your_domain.rhcloud.com/jboss-brms

成功後你就可以把import_demo_to_brms.zip 這個檔案透過brms的console中的 Administration -> Import Export tab匯入使用拉!

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 …
