This is a springboot project, and I have already added jakarta.activation-api in pom. Below is part of pom.xml:

                </configuration>
            </plugin>
        </plugins>
    </build>

I have already looked into these solutions, but are not working: SOAP Web Service - Can't generate classes from XSD What is the replacement for javax.activation package in java 9? I am using java 8, and following this tutorial: https://www.baeldung.com/spring-boot-soap-web-service

Any help is appreciated.

Compilation is successful after adding in pom.xml. But, still Java POJO classes are not generated. Below is the path available in pom.xml:

<plugin>
                    <groupId>org.codehaus.mojo</groupId>
                    <artifactId>jaxb2-maven-plugin</artifactId>
                    <version>1.6</version>
                    <executions>
                        <execution>
                            <id>xjc</id>
                            <goals>
                                <goal>xjc</goal>
                            </goals>
                        </execution>
                    </executions>
                    <configuration>
                        <schemaDirectory>${project.basedir}/src/main/resources/</schemaDirectory>
                        <outputDirectory>${project.basedir}/src/main/java/</outputDirectory>
                        <clearOutputDir>false</clearOutputDir>
                    </configuration>
                </plugin>

which `spring-boot` version do you use? – Panagiotis Bougioukos Sep 18 '22 at 10:41 — Panagiotis Bougioukos, Sep 18 '22 at 10:41

So, I was able to fix the issue by following these 2 steps:

install Jakarta EE: Web Services (JAX-WS) plugin to Intellij.
follow this to generate the java classes: https://www.jetbrains.com/help/idea/generate-java-from-xml-schema-using-jaxb-dialog.html
