User development, A new message was posted in the thread "Calling EJB from servlet - EJB's interface class not found": http://community.jboss.org/message/521289#521289 Author : jaikiran pai Profile : http://community.jboss.org/people/jaikiran Message: -------------------------------------------------------------- If you have the bean interfaces in the .war/WEB-INF/lib/somejar.jar, then i would have expected this to work - atleast not throw a ClassNotFoundException. Can you post the output of:   jar -tf somejar.jar   where somejar.jar is the one which is placed in .war/WEB-INF/lib and contains the bean interfaces.   As for the details around JBoss classloading, see these wiki pages:   http://community.jboss.org/wiki/ClassLoadingConfiguration http://community.jboss.org/wiki/JBossClassLoadingUseCases -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521289#521289
