Hi, I'm getting a little confused about the JBoss Modules dependencies available in the jboss-as-osgi-web project. I want to use the ModuleIdentifier class in this module in a DeploymentUnitProcessor, like the following public static class WebContextFactoryProcessor implements DeploymentUnitProcessor { @Override public void deploy(DeploymentPhaseContext phaseContext) throws DeploymentUnitProcessingException { DeploymentUnit depUnit = phaseContext.getDeploymentUnit(); ModuleIdentifier mid = depUnit.getAttachment(Attachments.MODULE_IDENTIFIER)); The jboss-as-osgi-web module itself has the dependency on the org.jboss.modules module: <module xmlns="urn:jboss:module:1.1" name="org.jboss.as.web"> <properties> <property name="jboss.api" value="private"/> </properties> <dependencies> <!-- ... --> <module name="org.jboss.modules"/> However, I'm getting a NoClassDefFoundError: java.lang.NoClassDefFoundError: org/jboss/modules/ModuleIdentifier at org.jboss.as.osgi.web.WebContextActivationProcessor$WebContextFactoryProcessor.deploy(WebContextActivationProcessor.java:82) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:116) [jboss-as-server-7.2.0.Alpha1-SNAPSHOT.jar:7.2.0.Alpha1-SNAPSHOT] I'm probably missing something obvious, anyone an idea? Cheers, David
