Chatbot throws JAXB-API excetpion

[sajjadpz]

I am running chatbot within IDE and it throws following exception

2018-07-12 13:20:18.019 ERROR [localhost-startStop-1] "chatbot" [com.sun.jersey.server.impl.wadl.WadlApplicationContextImpl] c.s.j.s.i.w.WadlApplicationContextImpl - Implementation of JAXB-API has not been found on module path or classpath.
javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath.

A bit of research showed that it it is related to Java-9 modularity and a worked around has already been implemented in pom.xml

<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<configuration>
					<!-- ~~~~~~~ support java 9 ~~~~~~~ -->
					<!-- https://blog.frankel.ch/migrating-to-java-9/1/ -->
					<jvmArguments>--add-modules java.xml.bind</jvmArguments>
				</configuration>
			</plugin>

which doesn't seem to work. May be someone can look into it who has more insight on this.
The application, however seems to work normally, its just an annoying error in the console 😄

@sajjadpz Does adding jaxb explicitly as pom dependency solve your problem? This code is there inside chatbot micro service but is not part of the parent pom.

<groupId>javax.xml.bind</groupId>

<artifactId>jaxb-api</artifactId>

<version>2.3.0</version>

[sajjadpz]

No it doesn't solve the issue.

[prasanthhs]

That seems to be the only solution available for this issue on the internet. A set of related dependancies to add to pom.xml to avoid this problem.

What is your JDK version? Update your JDK to 10 , it might be a java 8/9 problem

[Muzammil1234]

Try running by adding dependency at run time, something like this

java --add-modules=java.xml.bind -jar chatbot.jar, there must a way to add use this add module with spring-boot:run too, just search for it.

P.S: It's Guru here

@RicardoUsbeck - I have checked , jdk version is 10.

[sajjadpz]

@guru5590 - it is already added in pom.xml of parent project. Which itself passes those parameters at run time.
