Implementation of JAXB-API has not been found(when running java jar)

Question

I am getting error in the line (JAXBContext.newInstance):

    @Override
    public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
    SoapHeader soapHeader = ((SoapMessage)message).getSoapHeader();

    try {
        JAXBContext context = JAXBContext.newInstance(AuthHeader.class);
        Marshaller marshaller = context.createMarshaller();
        marshaller.marshal(authentication, soapHeader.getResult());

    } catch (JAXBException e) {
        System.out.println(e.getMessage());
        throw new IOException("error while marshalling authentication.");
    }
}

While it runs fine when this is executed as test case using:

 mvn install

or mvn:spring:boot run

But causes issue when the jar is run using:

java -jar target/fileName-0.0.1-SNAPSHOT.jar 

Error when running java -jar and hit using postman.

Implementation of JAXB-API has not been found on module path or classpath.

java.io.IOException: error while marshalling authentication.

Same jar runs fine on development server but doesn't run on staging server. Both development and staging server have same environment (java version, mvn, everything is same). I have these dependencies added to pom.xml:

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.3</version>
    </dependency>

If it's related to fat jar then why other dependencies like amazon s3, stripe etc. works with normal jar. What's the issue with jaxb only ?

I even tried to create fat jar using mvn package with the following config:

    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <executions>
            <execution>
                <goals>
                    <goal>repackage</goal>
                </goals>
                <configuration>
                    <mainClass>com.patracorp.patrapay.PatrapayApplication</mainClass>
                    <layout>ZIP</layout>
                </configuration>
            </execution>
        </executions>
    </plugin>

but still getting the same error.

Answer 1

1) Double check that you don't have duplicated dependencies, because JAXB artifacts had been renamed multiple times.

Running 'mvn dependency:tree' should not output JAXB related artifacts more than once.

2) Try to use this artifact:

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

Answer 2

In Java 9 and higher versions, Java has removed java.xml.bind from its default class path. So, you have to explicitly add JAR files to the classpath.

And adding only jaxb-impl won't suffice, I guess.
Can you add below dependency in your POM and then try it out.

    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>${jaxb-api.version}</version>
    </dependency>
    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>${jaxb-api.version}</version>
    </dependency>
    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-core</artifactId>
        <version>${jaxb-api.version}</version>
    </dependency>
