Configure JBoss / Wildfly Datasource with Maven

posted by Roberto Cortez on

Most Java EE applications use database access in their business logic, so developers are often faced with the need to configure drivers and database connection properties in the application server. In this post, we are going to automate that task for JBoss / Wildfly and a Postgre database using Maven. The work is based on my World of Warcraft Auctions Batch application from the previous post.

Maven Configuration

Let’s start by adding the following to our pom.xml:

We are going to use the Wildfly Maven Plugin to execute scripts with commands in the application server. Note that we also added a dependency to the Postgre driver. This is for Maven to download the dependency, because we are going to need it later to add it to the server. There is also a ${cli.file} property that is going to be assigned to a profile. This is to indicate which script we want to execute.

Let’s also add the following to the pom.xml:

With the Resources Maven Plugin we are going to filter the script files contained in the src/main/resources/scripts and replace them with the properties contained in ${basedir}/src/main/resources/ file.

Finally lets add a few Maven profiles to the pom.xml, with the scripts that we want to run:

Wildfly Script Files

Add Driver

The scripts with the commands to add a Driver:


Database drivers are added to Wildfly as a module. In this was, the driver is widely available to all the applications deployed in the server. With ${settings.localRepository} we are pointing into the database driver jar downloaded to your local Maven repository. Remember the dependency that we added into the Wildfly Maven Plugin? It’s to download the driver when you run the plugin and add it to the server. Now, to run the script we execute (you need to have the application server running):

mvn process-resources wildfly:execute-commands -P "install-driver"

The process-resources lifecycle is needed to replace the properties in the script file. In my case ${settings.localRepository} is replaced by /Users/radcortez/.m3/repository/. Check the target/scripts folder. After running the command, you should see the following output in the Maven log:

And on the server:


This script is to remove the driver from the application server. Execute mvn wildfly:execute-commands -P "remove-driver". You don’t need process-resources if you already executed the command before, unless you change the scripts.

Add Datasource

The scripts with the commands to add a Datasource:

We also need a a file to define the properties:

Default Java EE 7 Datasource

Java EE 7, specifies that the container should provide a default Datasource. Instead of defining a Datasource with the JNDI name java:/datasources/WowAuctionsDS in the application, we are going to point our newly created datasource to the default one with /subsystem=ee/service=default-bindings:write-attribute(name="datasource", value="${datasource.jndi}"). In this way, we don’t need to change anything in the application. Execute the script with mvn wildfly:execute-commands -P "install-wow-auctions". You should get the following Maven output:

And on the server:


This is the script to remove the Datasource and revert the Java EE 7 default Datasource. Run it by executing mvn wildfly:execute-commands -P "remove-wow-auctions"


This post demonstrated how to automate add / remove Drivers to Wildfly instances and also add / remove Datasources. This is useful if you want to switch between databases or if you’re configuring a server from the ground up. Think about CI environments. These scripts are also easily adjustable to other drivers.

You can get the code from the WoW Auctions Github repo, which uses this setup. Enjoy!
