Marshalling/Unmarshalling JSON or XML

[Geoff McKay]

Congrats Alex Soto Bueno & Jason Porter on your new book:
Quarkus Cookbook: Kubernetes-Optimized Java Solutions

On the topic of: Marshalling/Unmarshalling

Are there built in Handler functions to automate the process of writing Java objects to XML file (Marshalling) or converting XML content to Java objects (Unmarshalling)?

How "manual" is this process? Are there Handler functions to simplify and streamline the process?

Thanks!

Not one of the authors, but I was wondering what you mean by built-in. Built in what?

You can very easily marshal and unmarshal Java objects to and from XML using JAX-B. Some application containers provide a JAX-B implementation by default, and for others you need to bundle one with your application.

Hi Stephan,

Thanks! That answers my question.
Just looked into the JAXB Handler (Helper Class), and that's the solution I was looking for.
Appreciated

Quarkus has support for both JAX-B implementations and Jackson.

Have I got my terminology wrong, or wasn't JAXB part of the core JVM up until about Java 11?

[Stephan van Hulst]

That is correct. JAXB became a separate module around the time of Java SE 9, where it was still included in the JDK but marked as a deprecated module. It was fully removed from Java SE 11.

Later, it became a part of Jakarta EE 9.
