This is a springboot project, and I have already added jakarta.activation-api in pom. Below is part of pom.xml:
<dependency>
<groupId>wsdl4j</groupId>
<artifactId>wsdl4j</artifactId>
<version>1.6.2</version>
</dependency>
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
</dependency>
<dependency>
<groupId>jakarta.activation</groupId>
<artifactId>jakarta.activation-api</artifactId>
<version>1.2.2</version>
</dependency>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>

</executions>
<configuration>

<outputDirectory>${project.basedir}/src/main/java</outputDirectory>
<clearOutputDir>false</clearOutputDir>
</configuration>
</plugin>
</plugins>
</build>
I have already looked into these solutions, but are not working:
SOAP Web Service - Can't generate classes from XSD
What is the replacement for javax.activation package in java 9?
I am using java 8, and following this tutorial:
https://www.baeldung.com/spring-boot-soap-web-service
Any help is appreciated.
Compilation is successful after adding in pom.xml. But, still Java POJO classes are not generated. Below is the path available in pom.xml:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<id>xjc</id>
<goals>
<goal>xjc</goal>
</goals>
</execution>
</executions>
<configuration>
<schemaDirectory>${project.basedir}/src/main/resources/</schemaDirectory>
<outputDirectory>${project.basedir}/src/main/java/</outputDirectory>
<clearOutputDir>false</clearOutputDir>
</configuration>
</plugin>

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:
