Just after I create an ear Seam Project, there is a warning saying: Classpath entry org.jboss.ide.eclipse.as.classpath.core.runtime.ProjectRuntimeInitializer/JBoss 4.2 runtime will not be exported or published. Runtime ClassNotFoundExceptions may result. When I try to deploy the project to Jboss 4.2.1, I get 18:20:59,346 INFO [TomcatDeployer] deploy, ctxPath=/Teste8, warUrl=.../deploy/Teste8.war/ 18:20:59,783 ERROR [[/Teste8]] Error configuring application listener of class org.jboss.seam.servlet.SeamListener java.lang.ClassNotFoundException: org.jboss.seam.servlet.SeamListener I am using Jboss Tools 200708161644-nightly and the strange thing is that previously I was able to create and deploy Seam applications with the same configurations and version. Is there anything that I have to do by myself? thanks in advance, Fabrício Lemos View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4076041#...
