Apache Karaf loads all the configuration from etc/*.cfg files by default, using a mix of Felix FileInstall and Felix ConfigAdmin. These files are regular properties file looking like: Some values may be critical, and so not store in plain text. It could be critical business data (credit card number, etc), or technical data (password to […]

MDC logging with Apache Karaf and Camel

Jean-Baptiste Onofré - Sun, 08/31/2014 - 09:03
MDC (Mapped Diagnostic Context) logging is an interesting feature to log contextual messages. It’s classic to want to log contextual messages in your application. For instance, we want to log the actions performed by an user (identified by an username or user id). As you have a lot of simultaneous users on your application, it’s […]

Testing (utest and itest) Apache Camel Blueprint route

Jean-Baptiste Onofré - Thu, 08/28/2014 - 20:01
In any integration project, testing is vital for multiple reasons: to guarantee that the integration logic matches the expectations to quickly identify some regression issues to test some special cases, like the errors for instance to validate the succesful provisioning (deployment) on a runtime as close as possible to the target platform We distinguish two […]

Apache JMeter to test Apache ActiveMQ on CI with Maven/Jenkins

Jean-Baptiste Onofré - Wed, 08/27/2014 - 15:47
Apache JMeter is a great tool for testing, especially performance testing. It provides a lot of samplers that you can use to test your web services, web applications, etc. It also includes a couple of samplers for JMS that we can use with ActiveMQ.

Webex on Ubuntu 14.04

Jean-Baptiste Onofré - Fri, 08/22/2014 - 14:48
Webex is a great tool but unfortunately, it doesn’t work “out of the box” on Ubuntu 14.04 (and also with previous Ubuntu releases). For instance, the webex applet starts but it doesn’t refresh correctly, or the share of desktop/application doesn’t work. Actually, the issue is due to: some libraries required by webex are missing on […]

Apache Syncope backend with Apache Karaf

Jean-Baptiste Onofré - Sun, 08/17/2014 - 07:24
Apache Syncope is an identity manager (IdM). It comes with a web console where you can manage users, attributes, roles, etc. It also comes with a REST API allowing to integrate with other applications. By default, Syncope has its own database, but it can also “façade” another backend (LDAP, ActiveDirectory, JDBC) by using ConnId. In […]

Apache Karaf, Cellar, Camel, ActiveMQ monitoring with ELK (ElasticSearch, Logstash, and Kibana)

Jean-Baptiste Onofré - Mon, 03/17/2014 - 15:44
Apache Karaf, Cellar, Camel, and ActiveMQ provides a lot of information via JMX. More over, another very useful source of information is in the log files. If these two sources are very interesting, for a “real life” monitoring, we need some additional features: The JMX information and log messages should be stored in order to […]

Coming in Karaf 3.0.0: new enterprise JDBC feature

Jean-Baptiste Onofré - Mon, 12/16/2013 - 15:43
Some weeks (months ;)) ago, my colleague Christian (Schneider) did a good job by creating some useful commands to manipulate databases directly in Karaf. We discussed together where to put those commands. We decided to submit a patch at ServiceMix because we didn’t really think about Karaf 3.0.0 at that time. Finally, I decided to […]

Coming in Karaf 3.0.0: new enterprise JNDI feature

Jean-Baptiste Onofré - Fri, 12/13/2013 - 06:48
In previous Karaf version (2.x), the JNDI support was “basic”. We just leveraged Aries JNDI to support the osgi:service JNDI scheme to reference the OSGi services using JNDI name. However, we didn’t provide a fully functionnal JNDI initial context, nor any tooling around JNDI. In part of the new enterprise features coming with Karaf 3.0.0, […]

Coming in Karaf 3.0.0: RBAC support for OSGi services and console commands

Jean-Baptiste Onofré - Thu, 12/12/2013 - 10:27
In a previous post, we saw a new Karaf feature: support of user groups and Role-Based Access Controle (RBAC) for the JMX layer. We extended the RBAC support to the OSGi services, and by side effect to the console commands (as a console command is also an OSGi service). RBAC for OSGi services The JMX […]

In the first part of the “Talend ESB Continuous Integration” serie, we saw how to test the Camel routes created by the studio, by leveraging Camel Test Kit.

Coming in Karaf 3.0.0: JAAS users, groups, roles, and ACLs

Jean-Baptiste Onofré - Fri, 10/04/2013 - 15:34
This week I worked with David Booschaert. David proposed a patch for Karaf 3.0.0 to add the notion of groups and use ACL for JMX. He posted a blog entry about that: http://coderthoughts.blogspot.fr/2013/10/jmx-role-based-access-control-for-karaf.html. David’s blog is very detailed, mostly in term of implementation, the usage of the interceptor, etc. This blog is more about the […]

With my ActiveMQ friends (especially Dejan and Claus), I’m working on ActiveMQ 5.9 next release. Today, I focus on the HA with ActiveMQ, and especially Master-Slave configuration.
