The last of your messages is strange: anonymous wrote : vfsfile:/C:/jboss5/server/default/deploy/management/console-mgr.sar/ -> java.lang.NoSuchMethodError: org.jboss.system.server.ServerConfigLocator.locate()Lorg/jboss/system/server/ServerConfig; Seems a JBoss integrated app does not work. Do your own apps (ReportsWeb.war, crystaljsp.war) contain JBoss system classes from 4.2? Is your JBoss installation a plain new version, or did you add e.g. JARs to /common/lib or other directories?
