JEAP 5 - JBoss 加上 JON 監控後出現 Failed to load users/passwords/role files問題


問題的情況是這樣的,有些朋友在安裝JON 要監控JBoss EAP 5 的時候,出現

Failed to load users/passwords/role files 的 Exception.

這個問題的原因,是因為 JON 定時會呼叫 Connection Pool 的可用性

而呼叫的這個JMX Bean 本身就定義要去分別Mapping Connection Pool 與他的使用者資料,可是因為這些JBoss 的-ds.xml 中並沒有另外定義使用者的login 設定,因此它就會去抓default 位置,剛好這個default 位置沒有檔案,就出了這個Exception... 


(在JMX Console 也會出現相同的狀況)



1. 快速治標法

在 jboss-as/server/$PROFILE/conf 下建立 

2. 正確治本法

到所有的Data Source 上,設定 security domain, 一般普通的密碼設定是像這樣,




然後密碼的設定改放到 login–config.xml

<application-policy name="XXXDbRealm">
        <login-module code="" flag="required">
            <module-option name="principal">mma</module-option>
            <module-option name="userName">userxxx</module-option> <!--資料庫登入ID-->
            <module-option name="password">password xxx</module-option><!--資料庫登入密碼-->
            <module-option name="managedConnectionFactoryName">jboss.jca:service=LocalTxCM,name=PostgresDS/xxxschema</module-option>

這樣你的JMXBean 就可以正確抓到Data source 的 security domain 登入資訊資料了。

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

Select new, maven project, if you have installed the plugin correctly, you should …

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 …
