Hi all, I've been playing around with latest Camel 2.14 which introduces a new metrics-component. The information get exposed via JMX/XML. They use JAXB and bootstrapping Camel in a war on latest WildFly 8.1 (I used this a base: https://github.com/myfear/CamelEE7). If you use JConsole or hawtio+jolokia to access the relevant mbeans you get the following exception: NoClassDefFoundError: Could not initialize class com.sun.xml.bind.v2.model.impl.RuntimeBuiltinLeafInfoImpl Root cause is this: public static JAXBContext createJaxbContext() throws JAXBException { // must use classloader from CamelContext to have JAXB working return JAXBContext.newInstance(Constants.JAXB_CONTEXT_PACKAGES, CamelContext.class.getClassLoader()); } (https://github.com/apache/camel/blob/master/camel-core/src/main/java/org/...) Full stack: https://gist.github.com/myfear/7d95388bb22e313e5f4b Google lead me to some results about AS7 .. nothing worked so far. I tried: 1) MANIFEST.MF (expot services com.sun.xml.bind) 2) jboss-deployment-structure.xml <module name="com.sun.xml.bind" services="export" /> 3) packaging JAXB 2.2.6 in the war WildFly is the only server with those issues. It works on plain servlet containers like Tomcat and jetty. Any hints highly appreciated Thanks, Markus
