A few short words on the update of my Mule ESB Community Edition Docker images, to which I have included an image for the version 4 release candidate. Since there were problems running the version 4 release candidate on Alpine Linux due to the JavaScript scripting engine not being included or not working properly, I… Read More »
In this post I will show a workaround for a bug that appears when testing Mule flows that contains one or more validators from the relatively new Validations Module. The bug has been verified to be present in both Mule ESB 3.7.0 and 3.8.0. There are two issues in MuleSofts JIRA here and here, but the fix… Read More »
In this article I will show how to accomplish dependency injection of fields in tests that inherit from the Mule class FunctionalTestCase; both of dependencies to Spring beans and of values from property files. Background On an earlier occasion, I have attempted to use the standard @RunWith(SpringJUnit4ClassRunner.class) annotation in order to be able to have Spring… Read More »

After some searching I found some quite large files in the $MULE-HOME/bin directory which turned out to be heap-dump files. The cause for this turned out to be an additional wrapper parameter that is present in… Read More »

The old HTTP connectors and proxy pattern will be compared with the new with a focus on reliability under load and ease of configuration. I will also examine the best pre-3.6 alternative, as far as HTTP communication is… Read More »
In this article I will attempt to run the Mule ESB community edition in Docker in order to see whether it is feasible without any greater inconvenience. My goal is to be able to use Docker both when testing as well as in a production environment in order to gain better control over the environment… Read More »
Remote JMX Monitoring of a Mule Instance In this post I will describe how to enable monitoring of a remote Mule instance using JMX. In addition I will also enable the MX4J web interface that will expose the JMX properties of the Mule instance in a web application and I will install the Jolokia Mule… Read More »
In this post I will show how an embedded ActiveMQ broker is automatically started when using the broker URL “vm://localhost” in a Mule JMS connector, without any additional configuration, and how to disable this behaviour. I will also look at how to explicitly configure an embedded ActiveMQ broker in a Mule configuration file. As documented… Read More »
For some while I have been thinking about how to be able to develop reusable Mule configuration files containing, for instance, entire flows. Of course I have seen the strategy that uses property files and the Spring PropertyPlaceholderConfigurer to inject different values into Mule components depending on the values from the property files. While providing… Read More »
