In this article we will learn some of the available tools or plugins you can use to migrate your legacy Java EE/Jakarta EE 8 applications to the newer Jakarta EE environment. We will also discuss the common challenges that you can solve by using tools rather than performing a manual migration of your projects.
Java EE
Getting Started with Jakarta Data API
Jakarta Data API is a powerful specification that simplifies data access across a variety of database types, including relational and NoSQL databases. In this article you will learn how to leverage this programming model which will be part of Jakarta 11 bundle.
Getting started with Jakarta EE
This article will detail how to get started quickly with Jakarta EE which is the new reference specification for Java Enterprise API. As most of you probably know, the Java EE moved from Oracle to the Eclipse Foundation under the Eclipse Enterprise for Java (EE4J) project. There are already a list of application servers which offer a Jakarta EE compatible implementation such as WildFly. In this tutorial we will learn how to bootstrap a Jakarta EE project.
How to create Test Data in Jakarta EE applications
This article covers how to create sample random Data for your REST Services using a well-known library Data Faker. We will show how to bind a Fake Model to our Entity so that you can create sample Test Data in a snap!
How to create an EJB Startup Service
In this tutorial, we’ll explore how to use the @Startup and @Singleton annotations in Jakarta EE applications. These annotations allow us to initialize components during application startup and ensure that they are available throughout the application’s lifecycle. We’ll cover the basics of each annotation, how to use them together, and provide examples to illustrate their usage.
How to store JSON Data with JPA and Hibernate
Several databases provide varying levels of support for JSON data, including storage, indexing, querying, and manipulation capabilities. In this article we will explore how to insert and fetch JSON Data using Jakarta Persistence API and WildFly.
Java Multi-line and String Templates in Action
In this article we will learn how to use the Java Multi-line feature and and we can combine it with String Templates to create complex Object structures such as JSON payloads or even JSON Objects!
Working with JSON Arrays using Jakarta JSON API
JSON arrays are a fundamental data structure in JSON, used to store collections of values or objects. Java provides the JsonArray and JsonArrayBuilder classes from the Jakarta JSON API to efficiently create, manipulate, and parse JSON arrays. It also provides methods to parse a JSON Array into a Java Collection. In this tutorial we will see both options with practical examples
Mastering Jakarta JSON API from Java Applications
This tutorial will teach you how to use the Jakarta JSON Processing API from standalone Java applications. At the end of it, you will be able to create simple scripts in Java to manipulate, serialize and deserialize JSON content at scale.
How to change the default Web Service deployment Port ?
SOAP Web services running on WildFly or JBoss EAP 7 can customize the deployment port of the Web service by setting the wsdl-port or wsdl-secure-port of the webservices subsystem.
