Overview of this book

Jakarta EE stands as a robust standard with multiple implementations, presenting developers with a versatile toolkit for building enterprise applications. However, despite the advantages of enterprise application development, vendor lock-in remains a concern for many developers, limiting flexibility and interoperability across diverse environments. This Jakarta EE application development guide addresses the challenge of vendor lock-in by offering comprehensive coverage of the major Jakarta EE APIs and goes beyond the basics to help you develop applications deployable on any Jakarta EE compliant runtime. This book introduces you to JSON Processing and JSON Binding and shows you how the Model API and the Streaming API are used to process JSON data. You’ll then explore additional Jakarta EE APIs, such as WebSocket and Messaging, for loosely coupled, asynchronous communication and discover ways to secure applications with the Jakarta EE Security API. Finally, you'll learn about Jakarta RESTful web service development and techniques to develop cloud-ready microservices in Jakarta EE. By the end of this book, you'll have developed the skills to craft secure, scalable, and cloud-native microservices that solve modern enterprise challenges.

Chapter 15: Putting it All Together

Web Services with Jakarta XML Web Services

Web services are application programming interfaces that can be invoked remotely. Web services can be invoked from clients written in any language.

Jakarta EE includes the XML Web Services API as one of its technologies. We can use XML Web Services to develop SOAP (Simple Object Access Protocol) web services in the Java platform. Jakarta XML Web Services is a high-level API; invoking web services via Jakarta XML Web Services is done via remote procedure calls.

SOAP-based web services are now a legacy technology. In most cases, RESTful web services are preferred to SOAP-based services for new development. Knowledge of SOAP-based web services is primarily useful for maintaining legacy applications.

In this chapter, we will cover the following topics:

  • Developing web services with Jakarta XML Web Services
  • Exposing Enterprise Beans as web services
