I have a personal project using Hibernate with java 9, and it doesn’t seem to run at all! Follow the error:

log4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

I need to use Java 9 because of a dependency, so using Java 8 is not feasible. Follow the project’s github if you want to take a closer look: https://github.com/vitorjordao/bookper (the error will occur when trying to register someone).

Also add the code that generates the error in the format of a [mcve], Force those who want to help you download your project is not cool, make life easier for those who will help you adding here.

In the exception we have:

Caused by: java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

That is, did not find Jaxbexception (at runtime, only).

JAXB Apis are considered to be JAVA EE Apis, and therefore are no longer in the Java 9 default classpath.

Quick solution: Add modules that are no longer loaded by default with the command line option --add-modules java.se.ee

However, it is possible that these modules will be removed in future versions of Java. So...

Recommended solution is: Include your own copy in class path or module path. For example, to add JAX-B Apis as a Maven dependency:

<!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>
