Hi, I have been trying to get a simple seam application up and running on glassfish. Whenever i try to deploy the application on glassfish, i get an error: | App client jboss-seam.jar did not specify Main-Class in its manifest as described in the Java EE specification; no annotations in this app client will be processed | deployed with moduleid = seam-facelets | java.lang.NoClassDefFoundError: org/jboss/util/file/ArchiveBrowser$Filter | at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:125) | at com.sun.enterprise.server.PersistenceUnitLoaderImpl.load(PersistenceUnitLoaderImpl.java:149) | at com.sun.enterprise.server.PersistenceUnitLoaderImpl.load(PersistenceUnitLoaderImpl.java:84) | at com.sun.enterprise.server.AbstractLoader.loadPersistenceUnits(AbstractLoader.java:898) | at com.sun.enterprise.server.ApplicationLoader.doLoad(ApplicationLoader.java:184) | at com.sun.enterprise.server.TomcatApplicationLoader.doLoad(TomcatApplicationLoader.java:126) | at com.sun.enterprise.server.AbstractLoader.load(AbstractLoader.java:244) | at com.sun.enterprise.server.ApplicationManager.applicationDeployed(ApplicationManager.java:336) | at com.sun.enterprise.server.ApplicationManager.applicationDeployed(ApplicationManager.java:210) | at com.sun.enterprise.server.ApplicationManager.applicationDeployed(ApplicationManager.java:645) | at com.sun.enterprise.admin.event.AdminEventMulticaster.invokeApplicationDeployEventListener(AdminEventMulticaster.java:928) | I am at a loss as to what this means. Has some one got this exception before? Does this mean that i have missed out on some jar dependency some where or i have made some error in persistence.xml or elsewhere.. Any help would be greatly appreciated. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4100165#...
