WildFly Quickstarts

The quickstarts demonstrate Jakarta EE 8 and a few additional technologies from the WildFly stack. They provide small, specific, working examples that can be used as a reference for your own project.

1. Introduction

These quickstarts run on the WildFly application server. The quickstarts are configured to use the correct Maven dependencies and ensure that you test and compile the quickstarts against the correct runtime environment.

Each quickstart folder contains a README.adoc file that describes the quickstart features and provides instructions about how to build and run it. Instructions are provided to build the more readable README.html files.

Make sure you read this entire document before you attempt to work with the quickstarts.

2. System Requirements

The applications these projects produce are designed to be run on WildFly 16 or later.

All you need to build these projects is Java 8.0 (Java SDK 1.8) or later and Maven 3.3.1 or later.

3. Use of WILDFLY_HOME and QUICKSTART_HOME Variables

The quickstart README files use the replaceable value WILDFLY_HOME to denote the path to the WildFly server. When you encounter this value in a README file, make sure you replace it with the actual path to your WildFly server.

When you see the replaceable variable QUICKSTART_HOME, replace it with the path to the root directory of all of the quickstarts.

4. Prerequisites

Before you begin, you must perform the following tasks.

  1. Build the WildFly Server (Optional): This step is only required if you plan to run the latest development version of the WildFly server. It is not required if you are running a tagged or released version of the WildFly server.

  2. Build and Install the WildFly BOMs (Optional): This step is only required if you are building a development version of the WildFly server and see dependency issues when you build the quickstarts. It is not required if you are running a tagged or released version of the WildFly server.

  3. Build the Quickstart README.html Files (Required): The quickstart README files are written in AsciiDoc to provide modular, reusable content; however, this makes them difficult to read. For this reason, you must also build the quickstart README.html files from the AsciiDoc source.

4.1. Build the WildFly Server (Optional)

If you have downloaded a tagged or released version of the WildFly server, you can ignore this step. You can simply extract the WildFly server from the compressed file and start the server from that directory.

If you plan to run the development version of the WildFly server, you must first download and build the WildFly server from source.

  1. If you have not yet done so, you must clone WildFly server repository and navigate to it. You might also want to change the remote name from origin to upstream to be consistent with your other repositories.

    $ git clone git@github.com:wildfly/wildfly.git
    $ cd wildfly
    $ git remote rename origin upstream
  2. Verify that your local master branch contains the latest updates.

    $ git fetch upstream
    $ git checkout master
    $ git reset --hard upstream/master
  3. Build the WildFly server using the following command.

    $ mvn clean install -DskipTests -Denforcer.skip=true -Dcheckstyle.skip=true
  4. The WildFly server folder and ZIP files, which are named wildfly-VERSION-SNAPSHOT and wildfly-VERSION-SNAPSHOT.ZIP respectively, are located in the build/target/ directory. You can copy that folder or unzip the file to another location or start the server from that directory.

4.2. Build and Install the WildFly BOMs (Optional)

If you have downloaded and are running a tagged or released version of the quickstarts, you can ignore this step because the required BOMs are already installed in Maven.

If you are using the latest development version of the quickstarts and you are able to successfully build and deploy the quickstarts, you can also ignore this step because the required BOMS are already installed in Maven.

However, if you are using the latest development version of the quickstarts and you see build errors indicating missing dependencies, you must first build the latest WildFly server and then build and install the WildFly BOMs. This installs the latest Maven artifacts that are required by the SNAPSHOT version of the WildFly quickstarts that are still under development.

  1. If you have not yet done so, clone WildFly BOMs repository and navigate to it. You might also want to rename the directory to wildfly-boms to make it clear which BOMs it contains and also change the remote name from origin to upstream to be consistent with your other repositories.

    $ git clone git@github.com:wildfly/boms.git
    $ mv boms wildfly-boms
    $ cd wildfly-boms
    $ git remote rename origin upstream
  2. Verify that your local master branch contains the latest updates.

    $ git fetch upstream
    $ git checkout master
    $ git reset --hard upstream/master
  3. Build the WildFly BOMs using the following command.

    $ mvn clean install
    Note
    If you run into build errors, check with the WildFly team to see if the repositories are temporarily out of sync.
  4. At this point, you can verify that all of the quickstarts build using the following command.

    $ mvn clean install '-Pdefault,!complex-dependencies'

4.3. Build the Quickstart README.html Files (Required)

The quickstart README files are written in AsciiDoc, not only because the language is much more powerful than Markdown, but also also because it is possible to extract common instructions into separate files to be reused across the quickstarts. While this makes them more flexible and easier to maintain, unfortunately, included files do not render in a readable format in GitHub or in most text editors.

The Maven plugin that is used to build and deploy the quickstarts can also generate fully rendered README.html instructions from the README.adoc files.

To build all of the quickstart README.html files, including the root README.html file that contains the table with links to all available quickstarts, navigate to the root folder of the quickstarts and run the following command.

$ mvn clean package -Pdocs
Tip

To build the README.html file for a specific quickstart, navigate to the quickstart directory and run the above command.

If you see errors about missing dependencies, check the prerequisites section to determine whether you need to build the WildFly BOMs that corresponds to the version of the quickstarts that you are using.

5. Suggested Approach to the Quickstarts

We recommend that you approach the quickstarts as follows:

  • Regardless of your level of expertise, we suggest you start with the helloworld quickstart. It is the simplest example and is an easy way to prove the server is configured and running correctly.

  • If you are a beginner or new to JBoss, start with the quickstarts labeled Beginner, then try those marked as Intermediate. When you are comfortable with those, move on to the Advanced quickstarts.

  • Some quickstarts are based upon other quickstarts but have expanded capabilities and functionality. If a prerequisite quickstart is listed, make sure you deploy and test it before looking at the expanded version.

6. Run the Quickstarts Using the Maven Command Line

The root folder of each individual quickstart contains a README.html file with detailed instructions on how to build and run the example. In most cases you do the following:

Important
See the README file in each individual quickstart folder for specific details and information on how to run and access the example.

6.1. Build the Quickstart Archive

You can follow these steps to build the application to test for compile errors or to view the contents of the archive. See the specific quickstart README file for complete details.

  1. Open a terminal and navigate to the root directory of the quickstart you want to build.

  2. Use the following command if you only want to build the archive, but not deploy it.

    $ mvn clean install

6.2. Build and Deploy the Quickstart

This section describes the basic steps to build and deploy an application. See the specific instructions in each quickstart README file for any variations to this process.

  1. Make sure you start the WildFly server as described in the quickstart README file.

  2. Open a terminal and navigate to the root directory of the quickstart you want to run.

  3. Use the following command to build and deploy the archive.

    $ mvn clean install wildfly:deploy

6.3. Undeploy the Quickstart

Use the following command to undeploy the quickstart.

$ mvn wildfly:undeploy

7. Run the Quickstarts in Red Hat CodeReady Studio or Eclipse

You can also start the server and deploy the quickstarts or run the Arquillian tests from Eclipse using JBoss tools. For general information about how to import a quickstart, add a WildFly server, and build and deploy a quickstart, see Use Red Hat CodeReady Studio or Eclipse to Run the Quickstarts.

8. Configure Optional Components

The following components are needed for only a small subset of the quickstarts. Do not install or configure them unless the quickstart requires it.

8.1. Create Quickstart Users

Some of the quickstarts, particularly those that run in a secured mode and demonstrate security, require that you create quickstart users with different roles for authorization purposes. See Create Users Required by the Quickstarts for detailed instructions to create users required by the quickstarts.

8.2. Configure the PostgreSQL Database

Some of the quickstarts that demonstrate transactions require that you install and configure the PostgreSQL database. See Configure the PostgreSQL Database for Use with the Quickstarts for instructions.

8.3. Configure Byteman

A few of the quickstarts use Byteman to demonstrate distributed transaction processing and crash recovery. See Configure Byteman for Use with the Quickstarts for instructions.

9. Table of Available Quickstarts

All available quickstarts, which are listed in the following table, can be found here: {githubRepoUrl}.

Each quickstart provides the list of technologies demonstrated by the quickstart and the required experience level needed to build and deploy it. Click on the quickstart link in the table to see more detailed information about how to run it. Some quickstarts require deployment of other quickstarts. This information is noted in the Prerequisites section of the quickstart README.html file.

Note
Some of these quickstarts use the H2 database included with WildFly. It is a lightweight, relational example datasource that is used for examples only. It is not robust or scalable, is not supported, and should NOT be used in a production environment!
