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.

@areus Why do I need to manually add it ? It runs fine using mvn:spring-boot run but issue occurs only when using java -jar command. — Vivek Sadh, Apr 09 '20 at 04:23
Maven takes care of adding all dependencies to the classpath. If you want to run with `java -jar` you either need to manually add the dependencies to the classpath or you must configure maven to crear an uber jar. See https://www.baeldung.com/deployable-fat-jar-spring-boot — areus, Apr 09 '20 at 06:38
@areus Thanks for your response. I am using mvn install to create jar and I thought it would create a fat jar with dependencies. — Vivek Sadh, Apr 09 '20 at 09:55
Can you add the project git repo ? I want to test what is actually happening — Anish B., May 09 '20 at 04:32

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>

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>

Please share the results.

I know this fact. I already tried this thing from stackoverflow answers but doesn't work. Same error. – Vivek Sadh May 03 '20 at 17:17
@VivekSadh : I tried and brought the application to same error but it was due to missing `jaxb-impl` artifact in pom.xml or classpath . So, Please check your classpath where this issue is happening. Otherwise ,If you can reproduce it to dummy situation , it can be more analyzed. – Tarun May 04 '20 at 19:36
@VivekSadh Were you able to figure it out? I tried adding all 6 dependencies and it still doesnt work(jaxb-api, jaxb-impl, jaxb-core, jaxb-runtime, jakarta.xml.bind-api, jakarta.annotation-api)? Tried different permutations of these as suggested by 5-6 SO posts, but none worked so far in Java 17 – theprogrammer Mar 10 '23 at 18:50
