Configuration in WildFly is centralized, simple and user-focused. The configuration file is organized by subsystems that you can easily comprehend and no internal server wiring is exposed. All management capabilities are exposed in a unified manner across many forms of access.

These options allow for custom automation using the tools and languages that best fit your needs. WildFly does classloading right. It uses JBoss Modules to provide true application isolation, hiding server implementation classes from the application and only linking with JARs your application needs.

Visibility rules have sensible defaults, yet can be customized. The dependency resolution algorithm means that classloading performance is not affected by the number of versions of libraries you have installed. WildFly takes an aggressive approach to memory management.

The base runtime services were developed to minimize heap allocation by using common cached indexed metadata over duplicate full parses, which reduces heap and object churn.

It starts instantly and requires zero memory on the server. These optimizations combined enable WildFly to run with stock JVM settings and also on small devices while leaving more headroom for application data and supports higher scalability. These improve developer productivity by providing rich enterprise capabilities in easy to consume frameworks that eliminate boilerplate and reduce technical burden.

This allows your team to focus on the core business needs of your application. By building your application on standards you retain the flexibility to migrate between various vendor solutions. This means the default setting has been switched from enabled to disabled and the plan is to remove support for it from the Java Virtual Machine in a pending release. We need your help seeing if this affects WildFly performance in your application.

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.

All you need to build these projects is Java 8. 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. 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.

Install the Quickstart Parent Artifact in Maven Optional : This step is only required if you are running the latest development version of the quickstarts. It is not required if you are running a tagged or released version of the quickstarts. 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 serveryou must first download and build the WildFly server from source. 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.

You can copy that folder or unzip the file to another location or start the server from that directory. 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. 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.

The root POM. If you have downloaded and are running a tagged or released version of the quickstarts, you can ignore this step because the quickstart-parent artifact is already installed in Maven.

If you are running the latest development version of the quickstarts, you must install the quickstart-parent artifact so its dependencies are available to the quickstarts that need it. 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.

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. 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 Beginnerthen 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.

In most cases you do the following:. Start the WildFly server. Optionally, you can build the quickstart archive to test for compile errors. You can follow these steps to build the application to test for compile errors or to view the contents of the archive.Welcome to the WildFly Documentation. The documentation for WildFly is split into two categories:. Administrator Guides for those wanting to understand how to install and configure the server.

Developer Guides for those wanting to understand how to develop applications for the server. There is also the WildFly Model Reference that provides information about all subsystem configuration options generated directly from the management model. The Getting Started Guide shows you how to install and start the server, how to configure logging, how to deploy an application, how to deploy a datasource, and how to get started using the command line interface and web management interface.

The Admin Guide provides detailed information on using the CLI and Web Management interface, how to use the domain configuration, and shows you how to configure key subsystems. The High Availability Guide shows you how to create a cluster, how configure the web container and EJB container for clustering, and shows you how to configure load balancing and failover.

Each tutorial is accompanied by a quickstart, which contains the source code, deployment descriptors and a Maven based build. The Developer Guide in progress takes you through every deployment descriptor and every annotation offered by WildFly. The Extending WildFly guide walks you through creating a new WildFly subsystem extension, in order to add more functionality to WildFly, and shows how to test it before plugging it into WildFly.

The WildFly Client Configuration guide walks you trough new wildfly client and how to use it. WildFly comes with a number of quickstarts, examples which introduce to a particular technology or feature of the application server.

Build, deploy and manage your applications across cloud- and on-premise infrastructure. June 16, by Jorge Morales. This tutorial walks you through the creation of an application titled myapp. The sample application used in this tutorial is a simple Java Web application with a single Jsp file that prints out a Hello World message. You do not have to use our sample application, but for the first steps it might be helpful.

To create a new application you need to have your source code hosted somewhere on the internet and have it accessible using git. For example, our sample application is hosted at GitHub. For this tutorial you may use the code from the provided repository or you can fork the repository.

Forking is necessary if you want to follow also through Step 2. Once ready, open a terminal and at the command prompt, enter the following command to create a Java web application replace the username URL if you have forked, or the whole URL if you are using your own application :. WildFly Run 'oc status' to view your app. OpenShift automatically linked wildfly with version You could as well use wildfly as prefix to deploy using the specific version, e. OpenShift prints a lot of information that is not that important for us at this moment, what we care about is if our application is accessible from the internet and if we can see it running.

For exposing application to the outside world, OpenShift has a concept of routes that map domain names to specific applications.

OpenShift automatically created new service, according to the name of the application. There again is a lot of information that we mostly do not care about at this moment but what we need is the first line. It shows you the domain, your application is available at. To access the application, simply open the domain in your browser of choice and you should see a Hello World message. You can deploy your application using web console as well as with cli tools.

To deploy using web, click on the Add to project in the top bar.

Then type wildfly into the Filter by keyword text field. And you will see list of WildFly based templates similar to:.

Clicking the URL in the top white box will take you straight to your newly deployed application that will show the Hello World message. To make changes to the application, you need to fork it and deploy from your own fork instead of from the original repository of the sample application. If you choose to do so, there is no need to copy the source code to your local machine and can skip directly to Step 2.

Or you can clone the repository locally, edit the file, and push back to the server. To do so, first clone the git repository and enter the new directory. OpenShift already knows how to reach your git repository as it did while first deploying the application. As it created the service that we referenced before it also created buildconfig buildconfig "myapp" created.
