Refactor Java code safely — and automatically — with OpenRewrite.

Refactoring big codebases by hand is slow, risky, and easy to put off. That’s where OpenRewrite comes in. The open-source framework for large-scale, automated code transformations helps teams modernize safely and consistently.

Each month, the creators and maintainers of OpenRewrite at Moderne run live, hands-on training sessions — one for newcomers and one for experienced users. You’ll see how recipes work, how to apply them across projects, and how to modernize code with confidence.

Join the next session, bring your questions, and learn how to automate the kind of work that usually eats your sprint time.

Distributed systems often come with complex challenges such as service-to-service communication, state management, asynchronous messaging, security, and more.

Dapr (Distributed Application Runtime) provides a set of APIs and building blocks to address these challenges, abstracting away infrastructure so we can focus on business logic.

In this tutorial, we'll focus on Dapr's pub/sub API for message brokering. Using its Spring Boot integration, we'll simplify the creation of a loosely coupled, portable, and easily testable pub/sub messaging system:

1. Overview

GlassFish Server is an open-source application server for developing and deploying Java Enterprise applications. Also, it provides support for web containers, load balancing, an administrative console for configuration and management, etc.

In this tutorial, we’ll learn step-by-step the process for configuring GlassFish Server within Eclipse IDE.

2. GlassFish Server in Eclipse IDE

To configure the GlassFish server in Eclipse IDE, we must install the Eclipse IDE for Enterprise Java and Web Developers on our machine.

The Eclipse IDE for Enterprise Java Developers extends the functionality of the Standard Eclipse IDE. It has additional tools to bootstrap the Java EE/Jakarta EE application.

2.1. GlassFish Tool

Eclipse IDE for Enterprise Java Developers, by default, is bundled with tools to set up popular web servers like Tomcat, WebSphere, etc. However, the GlassFish Tool isn’t installed by default.

The Oracle Enterprise Pack for Eclipse contains Eclipse GlassFish Tools. Let’s add the plugin repository “http://download.oracle.com/otn_software/oepe/12.2.1.8/oxygen/repository/dependencies/” to Eclipse IDE to install the GlassFish tool.

First, let’s click on the Help option in the menu bar and select Install New Software. Then, let’s add the link to the Oracle Enterprise Pack to install the GlassFish Tool:
install_glassfishtool_from_oracle_pack

Here, we add the link to Oracle Enterprise Pack and press the Enter key. All the available software is loaded, but our interest is in the GlassFish tool. Hence, we select the GlassFish tool and click the Next button to install the tool.

After installation, let’s restart the Eclipse IDE and check the GlassFish tool. First, let’s click on the Windows option in the menu bar. Next, let’s click on the Show View option. Finally, let’s choose the Servers option:server_view_within_eclipse

We now have Servers in our view. Let’s click on the link “Create New Server” to see the GlassFish Tool:glassfish_tool_in_eclipse

Notably, the current GlassFish tool in Eclipse IDE for Enterprise Java Developer supports only GlashFish versions 1, 3, and 5.

2.2. Setting up GlassFish Server

Furthermore, let’s download GlassFish 5.1 and extract it to a folder. Notably, GlassFish 5.1 provides support for only Java 8.

Next, let’s click on Create a new server in the Servers view. This opens the server tools, and let’s select GlassFish:add_new_glassfish_server_runtime

Here, we click on Create a new server and select GlassFish. Additionally, we click on the Add option to create the GlassFish runtime environment by specifying the path to the extracted GlassFish server.

Alternatively, we can right-click in the Servers view and select the “New” option to add a new server.

After clicking the Add option, let’s specify the path to the server and JDK:

glass_fish_runtime_property

In the above image, we define the path to the GlassFish server and the JDK. Finally, we click on the Finish button to add the GlassFish runtime properties.

Next, let’s go back to the New Server view and select the GlassFish server runtime we just created:select_glassfish_runtime_configuration

The Next button takes us to a page to define the server properties like the Admin password:define_glassfish_property

For simplicity, we didn’t define the admin username and password.

The Next button takes us to a page to add resources to the server:deploy_an_application_server

Our goal is to set up a server, so we leave the configured box empty and click Finish.

The server is now fully set up and can be assessed from the Servers view:server_added_to_server_view_and_can_be_started

The server is now listed in the Servers view. Next, let’s select it and click on the start button to start the server.

Finally, let’s open the URL “http://localhost:8080” in our browser to see the running server:index_page_of_glassfish_server

The above image shows the index page of the running server.

3. Conclusion

In this article, we learned how to setup a GlassFish server within the Eclipse IDE through a step-by-step guide.

Additionally, we saw how to install the Eclipse GlassFish tools via the Oracle Enterprise Pack.

Modern Java teams move fast — but codebases don’t always keep up. Frameworks change, dependencies drift, and tech debt builds until it starts to drag on delivery. OpenRewrite was built to fix that: an open-source refactoring engine that automates repetitive code changes while keeping developer intent intact.

The monthly training series, led by the creators and maintainers of OpenRewrite at Moderne, walks through real-world migrations and modernization patterns. Whether you’re new to recipes or ready to write your own, you’ll learn practical ways to refactor safely and at scale.

If you’ve ever wished refactoring felt as natural — and as fast — as writing code, this is a good place to start.
