NoClassDefFoundException in seam-gen generated code !!!
simplex-software Jan 23, 2008 12:32 PMGreetings,
After having ran "seam generate-entites" on my db and after having deployed the EAR, I got the following exception in the log file:
2008-01-23 17:16:58,786 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/SimplexCRM]] Exception lors de l'envoi de l'évènement contexte initialisé (context initialized) àl'instance de classe d'écoute (listener) org.jboss.seam.servlet.SeamListener java.lang.RuntimeException: Could not create Component: accountsAuditHome at org.jboss.seam.init.Initialization.addComponent(Initialization.java:976) at org.jboss.seam.init.Initialization.installComponents(Initialization.java:903) at org.jboss.seam.init.Initialization.init(Initialization.java:548) at org.jboss.seam.servlet.SeamListener.contextInitialized(SeamListener.java:34) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3854) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4359) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:761) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:741) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:553) ................. etc.
The reason of this exception is displayed further, in the log file:
Caused by: java.lang.NoClassDefFoundError: fr/simplexSoftware/crm/jpaBeans/AccountsAuditId at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Class.java:2427) at java.lang.Class.privateGetPublicMethods(Class.java:2547) at java.lang.Class.getMethods(Class.java:1410) at org.jboss.seam.Component.hasAnnotation(Component.java:1059) at org.jboss.seam.Component.<init>(Component.java:228) at org.jboss.seam.Component.<init>(Component.java:216) at org.jboss.seam.init.Initialization.addComponent(Initialization.java:961) ... 139 more
The EAR file contains in its lib directory a jar which contains all the required classes, including the one flagged as missing. The application.xml correctly defines the modules, so I don't understand how is it possible that this exception is raised, given that all the classes are there.
Could anybody help please ?
Many thanks in advance.
