Caused by: java.lang.ClassNotFoundException: jakarta.xml.bind.JAXBException – Java

The Problem:

I’m upgrading a Springboot application from version 2.x to 3.x. After the upgrade, the application fails to start with the following error: java.lang.ClassNotFoundException: jakarta.xml.bind.JAXBException. Can you guide me in resolving this issue?

The Solutions:

Solution 1: Add Required Dependencies

In Spring 3, the javax.xml.bind package is no longer included in the default classpath, which is required for JAXBException. To resolve this issue, add the following dependencies in your pom.xml or build.gradle file:

For Maven:

<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.2</version>
</dependency>

<dependency>
    <groupId>jakarta.xml.bind</groupId>
    <artifactId>jakarta.xml.bind-api</artifactId>
    <version>2.3.2</version>
</dependency>

For Gradle:

implementation 'org.glassfish.jaxb:jaxb-runtime:2.3.2'
implementation 'jakarta.xml.bind:jakarta.xml.bind-api:2.3.2'

By adding these dependencies, you can ensure that the necessary JAXB libraries are available for your application to run successfully.
