java.lang.ClassNotFoundException: javax.xml.bind.JAXBException


I’m new to Camunda and I try to get a local installation running for evaluating the engine in our company. I use a tomcat 9.0.10 and java 9.0.4 under macOS 10.13.6. I deployed camunda with the war-file using the Tomcat Web Application Manager.

When I try to start the application I get the error: FAIL - Application at context path [/camunda] could not be started

Catalina.out-log says: java.lang.ClassNotFoundException: javax.xml.bind.JAXBException

So I did some research on the web and it seems that in Java 9 javax.xml.bind is no longer included in the classpath. How can I solve this issue on my local installation?

Would appriciate any help on this.

Hi Christian,

Currently only Java 9 is not supported (support env).
Supporting more recent Java version is in our roadmap for the next minor version.

Best regards,

Thank you for the fast answer.

Somehow you need to get: “–add-modules” into your JAVA_OPTS. I’m using the camunda distribution that includes tomcat downloaded from here:

All I did to get it working was to add:

export JAVA_OPTS="–add-modules"

to the file “” file.
