Hi Guys, I'm using Arquillian to test my JSF beans in an embedded Tomcat 7.0.27 container. Problem is, I'm getting this exception when I run maven test: see http://pastebin.com/Ewiwe2CQ I have the following pom.xml: see http://pastebin.com/u2UuakAc Here's my Unit Test Class: @RunWith(Arquillian.class) publicclassUserBeanTest{ @Deployment publicstaticWebArchivecreateDeployment(){     MavenDependencyResolverresolver =DependencyResolvers.use(MavenDependencyResolver.class).loadMetadataFromPom("pom.xml");     WebArchivewar =ShrinkWrap.create(WebArchive.class)         .setWebXML(newFile("src/main/webapp/WEB-INF/web.xml"))         .addAsWebResource(newFile("src/main/webapp/WEB-INF/faces-config.xml"),"/WEB-INF/faces-config.xml")         .addClass(UserBean.class);     war.addAsWebResource(newFile("src/main/webapp","user.xhtml"));     //add these libraries only for non JEE containers (e.g. tomcat)     war.addAsLibraries(resolver.artifact("org.apache.myfaces.core:myfaces-api:2.1.5").resolveAsFiles());     war.addAsLibraries(resolver.artifact("org.apache.myfaces.core:myfaces-impl:2.1.5").resolveAsFiles());     returnwar; } @Test @InitialPage("/user.jsf") publicvoidshould_create_greeting(JSFServerSessionserver,JSFClientSessionclient){     //some tests here } } The problem seems to occur during deployment of the WebArchive when the Arquillian tests run, and not when my @Test methods run. I was able to make things work by using managed tomcat. But I'd prefer an embedded tomcat though. Has anyone had better luck with this? Best Regards, Paul
