Super easy guide: inject your portlets wherever you want!

eXo Platform Blog

With our extension mechanism, we can now package and deploy new features easily in eXo Platform 4 as add-ons. You can deploy your own portlets but also existing ones, ready to use and ready to be deployed, with the add-ons manager:


Platform 4.1 has a new way to inject your portlets easily into pre-established places within the platform. It’s easy and we have covered most of the places you will need. Of course, the feature is extensible, which means you can define new places and then inject your portlets wherever you want

Let’s say you want to inject your new add-on into the Platform to add a simple new application on the top right of your Home:


Most of the changes are going to be made within your WAR file in the file /webapp/WEB-INF/conf/portlet/dynamic-container-configuration.xml.

This file is imported into configuration.xml within the WAR. The goal is to redefine a configuration file from the WAR without overriding the previous one present with the exact same location and name in your Platform. (documentation).


This file declares the new add-on but also the container name where you want to inject it.

Your JAR should contain your backend and the portal container configuration in file /src/main/resources/conf/configuration.xml.


In this file we are updating the portlet configuration from the PortalContainerConfig to register the new sampleDynamicContainer in the PortalContainerDefinitions.


That’s just an example for a social intranet. With the new dynamic container we have provided, you are going to be able to inject your portlets more easily and safely.

You will find this example of packaging on the eXo Samples Repository. In the meantime, if you want to try ready-to-use add-ons for your Platform, check out the add-ons repository and of course you can submit your add-ons to the community!
