Install WildFly 18 and Connect to Eclipse IDE on Ubuntu 20.04|18.04

ComputingForGeeks

When developing Java EE/Jakarta EE projects, you know you will need a Java server. Some of the most used Java Enterprise servers include Apache Tomcat, Glassfish, Jetty and WildFly/JBoss server. Not all these server provides all needed features but all of them provide most of the enterprise features needed. Glassfish and WildFly/JBoss provides a complete set of features and is mostly used by enterprises.

For CentOS: Install WildFly (JBoss) Server on CentOS 8 / CentOS 7

In this article, I will show you how to install WildFly 18. But first, what is the difference between Wildfly and JBoss AS? Wildfly is the community edition for the Java EE server while JBoss As is the enterprise edition for the enterprise. Both are sponsored by Redhat Inc. So JBoss AS simply put is the secured version of WildFly.

So obviously the first thing to do is to have Java installed.

$ sudo apt install -y default-jdk
$ java -version
openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3)
OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Ubuntu-1ubuntu218.04.3, mixed mode, sharing)

Install WildFly 18 on Ubuntu 20.04|18.04

We will download WildFly 18 and choose the location to install. I am installing mine at ~/eclipse/servers/

mkdir -p ~/eclipse/servers
cd ~/eclipse/servers
wget https://download.jboss.org/wildfly/18.0.1.Final/wildfly-18.0.1.Final.zip
unzip wildfly-18.0.0.Final.zip

After that, we add an administrator to manage some sources such as data sources.

cd wildfly-18.0.0.Final/bin/
./add-user.sh

Follow instructions as shown below to fill the questions:

Instructions while configuring an administrator

After the configuration, start your WildFly server instance in standalone as follows:

$ ./standalone.sh

When the server is running, the web management interface can be accessed at http://localhost:9990/console. You can use the web management interface to create datasources, manage deployments and configure the server.
