It looks like you have set all required references, but nevertheless, could you please check once more 1) In web project, file .settings\org.jboss.tools.seam.core.prefs contains lines seam.ear.project=%ear project name% seam.ejb.project=%ejb project name% 2) In ear project, file .settings\org.eclipse.wst.common.component includes ejb project as dependent module 3) In ejb project, file .settings\org.jboss.tools.seam.core.prefs contains line seam.parent.project=%web project name% If that is ok, then try cleaning seam model as follows. Close Eclipse, remove all files in directory %workspace%/.metadata/.plugins/org.jboss.tools.seam.core/projects, restart Eclipse and clean/rebuild workspace. If it does not help, then we may need to see the exact structure of your projects to study the problem. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4194340#...
