| [jetty-users] Jetty 9.3.9.v20160517 Provider WebSocketCdiInitializer not found when enabling Annotations |
| This question has been posted on StackOverflow, and despite a bounty, does not seem to attract any answer. Could someone on the mailing list help us ? The text posted on StackOverflow follows: When deploying a webapp using the `DeploymentManager`, this error is thrown 2016-06-06 15:19:37,750 WARN [org.eclipse.jetty.deploy.DeploymentManager] (WrapperSimpleAppMain) Unable to reach node goal: started (DeploymentManager.java:506) java.util.ServiceConfigurationError: javax.servlet.ServletContainerInitializer: Provider org.eclipse.jetty.cdi.websocket.WebSocketCdiInitializer not found at java.util.ServiceLoader.fail(ServiceLoader.java:239) at java.util.ServiceLoader.access$300(ServiceLoader.java:185) at java.util.ServiceLoader$LazyIterator.nextService(ServiceLoader.java:372) at java.util.ServiceLoader$LazyIterator.next(ServiceLoader.java:404) at java.util.ServiceLoader$1.next(ServiceLoader.java:480) at org.eclipse.jetty.annotations.AnnotationConfiguration.getNonExcludedInitializers(AnnotationConfiguration.java:864) at org.eclipse.jetty.annotations.AnnotationConfiguration.configure(AnnotationConfiguration.java:444) at org.eclipse.jetty.webapp.WebAppContext.configure(WebAppContext.java:494) at org.eclipse.jetty.webapp.WebAppContext.startContext(WebAppContext.java:1361) at org.eclipse.jetty.server.handler.ContextHandler.doStart(ContextHandler.java:772) at org.eclipse.jetty.servlet.ServletContextHandler.doStart(ServletContextHandler.java:262) at org.eclipse.jetty.webapp.WebAppContext.doStart(WebAppContext.java:520) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:68) This happens when enabling annotations support using: org.eclipse.jetty.webapp.Configuration.ClassList classlist = org.eclipse.jetty.webapp.Configuration.ClassList.setServerDefault(server); classlist.addBefore( "org.eclipse.jetty.webapp.JettyWebXmlConfiguration", "org.eclipse.jetty.annotations.AnnotationConfiguration" ); classlist.addAfter( "org.eclipse.jetty.webapp.FragmentConfiguration", "org.eclipse.jetty.plus.webapp.PlusConfiguration" ); The jar `cdi-websocket-9.3.9.v20160517.jar` is in the class path This [issue][1] suggests to deactivate the `cdi` Jetty module, but it does not say how to do it with an embedded Jetty. How do I fix this ? **EDIT** We realize that this issue may be caused by the (complex) environment the application is running in. Therefore, I am particularly interested in understanding **what** are the root reasons that could cause this exception to be thrown |
