In this mini-tutorial we will demonstrate the configuration of a pristine development environment with Eclipse, JBoss Tools and Wildfly Application Server on MacOS.

From JBoss with love

If you have been in the Java EE space for a couple of years, Eclipse IDE for Java Enterprise Developers is probably one of the best IDE experiences, making an easy task the creation of applications with important EE components like CDI, EJB, JPA mappings, configuration files and good interaction with some of the important application servers (TomEE, WebLogic, Payara, Wildfly, JBoss).

In this line, Red Hat develops the Eclipse variant 'CodeReady Studio' giving you and IDE with support for Java Enterprise Frameworks, Maven, HTML 5, Red Hat Fuse and OpenShift deployments.

To give support to its IDE, Red Hat also publishes CodeReady plugins as an independent project called JBoss Tools, enabling custom Enterprise Java development environments with Eclipse IDE for Java Enterprise developers as basis, which we demonstrate in this tutorial.

Why? For fun. Or as in my case, I don't use the entire toolset from Red Hat.

Eclipse

Requirements

In order to complete this tutorial you will need to download/install the following elements:

1- Java 11 JDK from Oracle or any OpenJDK distro
2- Eclipse IDE for Enterprise Java Developers
3- Wildfly 16

Installing OpenJDK

Since this is an OS/distribution dependent step, you could follow tutorials for Red Hat's OpenJDK, AdoptOpenJDK, Ubuntu, etc. At this time, Wildfly has Java 11 as target due new Java-LTS version scheme.

For MacOS one convenient way is AdoptOpenJDK tap.

First you should install Homebrew

After that and if you want an specific Java version, you should add AdoptOpenJDK tap and install from there. For instance if we like a OpenJDK 11 instance we should type:

If all works as expected, you should have a new Java 11 environment running:

Eclipse IDE for Enterprise Java Developers

Eclipse offers collections of plugins denominated Packages, each package is a collection of common plugins aimed for a particular development need. Hence to simplify the process you could download directly Eclipse IDE for Enterprise Java Developers.

On Mac you will download a convenient .dmg file that you should drag and drop on the Applications folder.

The group rG released Acronis True Image 2020 build 22510 Bootable ISO Retail Multilingual for the Windows platform. For more info, please visit product’s home page.

The result is a brand new Eclipse Installation with Enterprise Java (Jakarta EE) support.

JBoss Tools

To install the 'Enterprise Java' Features to your Eclipse installation, go to JBoss Tools main website at https://tools.jboss.org/ you should double check the compatibility with your Eclipse version before installing. Since Eclipse is lauching new versions each quarter the preferred way to install the plugins is by adding the update URL .

First, go to:

And add the JBoss Tools URL http://download.jboss.org/jbosstools/photon/development/updates/

After that you should select the individual features, a minimal set of features for developers aiming Jakarta EE is:

  • JBoss Web and Java EE Development: Support for libraries and tools like DeltaSpike, Java EE Batch, Hibernate, JavaScript, JBoss Forge
  • JBoss Application Server Adapters: Support for JBoss, Wildfly and OpenShift 3
  • JBoss Cloud and Container Development Tools: Support for Vagrant, Docker and Red Hat Containers development kit
  • JBoss Maven support: Integrations between Maven and many EE/JBoss APIs

Finally you should accept licenses and restart your Eclipse installation.

Wildfly 16

Wildfly distributes the application server in zip or tgz files. After getting the link you could do the install process from the CLI. For example if you wanna create your Wildfly directory at ~/opt/ you should execute the following commands

It is also convenient to add an administrative user that allows the creation of DataSources, Java Mail destinations, etc. For instance and using again ~/opt/ as basis:

The script will ask basic details like user name, password and consideration on cluster environments, in the end you should have a configured Wildfly instance ready for development, to start the instance just type:

To check your administrative user, go to http://localhost:9990/console/index.html.

Eclipse and Wildfly

Once you have all set, it is easy to add Wildfly to your Eclipse installation. Go to servers window and add a new server instance, the wizard is pretty straight forward so screenshot are added just for reference:

If you wanna go deep on server's configuration, Eclipse allows you to open the standalone.xml configuration file directly from the IDE, just check if the application server is stopped, otherwhise your configuration changes will be deleted.

Testing the environment

To test this application I've created a nano-application using an Archetype for Java EE 8. The application server and the IDE support Java 11 and the deployment works as expected directly from the ide.

Eclipse Java Enterprise Developer Tools 2020

Yesterday, Ian posted an entry in his blog asking for community help to test a new downloads page that we’d like to realize for the Europa release. On this page are several new distributions of Eclipse. I’ve been testing various version of these packages for a while, and—for a first release—it’s looking pretty good.

Eclipse Java Enterprise Developer Tools Free

Over the last few days, I’ve been reviewing the 'Eclipse Tools for Java Enterprise Developers' package. This package contains the tools that you need to build, test, debug, and refactor Java, as well as tools for building applications based on Java EE technologies like servlets, JavaServer Pages, Enterprise JavaBeans, and web services (including support for Java EE 5). It also includes tools for editing HTML, CSS, and XML files, and more.

I’ve used it to all sorts of things including building and deploying applications on Tomcat 5.5 and 6.0, and JBoss 4.2. It all works swimmingly. One wrinkle is that the application servers themselves aren’t part of the package; you have to download and unpack these separately. Mercifully, you don’t have to do any configuration: the Eclipse Web Tools takes care of setting up instances of the application servers for you to test your code against.

Something that’s new is the Web Page Editor. I’ve been using this to touch up some HTML pages on a site that I maintain. I’ve also been tinkering with a few JSPs. I haven’t had the guts yet to try JSF (for some intangible reason, JSF scares me), but apparently that’s supported as well. Here’s a screenshot of the Web Page Editor in action:
It occurred to me to try and force it to work with PHP files (by adding a file association in the preferences), but it didn’t work. The Web Page Editor just doesn’t understand the tags. However, the beauty of having an extensible framework means that extensions to support that sort of thing should hopefully be something we can look forward to in the future.

Eclipse Java Enterprise Developer Tools

Overall, I’m happy with the package. I like that it includes Mylar. I like that it doesn’t include the PDE or any of the source code (Java EE developers don’t need these). I’d like to see a future version include Subversion support, but that depends on the Subversive team getting an Eclipse 3.3-compatible release ready.

Bug 187879 has become the rallying point for discussion about our potential new download page; it also contains some discussion about the content of the packages. If you’re interested in helping to improve the Eclipse experience for new developers, please add your comments to this bug. If you find specific problems with any of the packages or just want to add your thoughts about what the existing packages should contain, look for (or contribute new) bugs against the EPP project. Of course, there’s also the EPP newsgroup.
