[Users] Failed to start service jboss.deployment.subunit."engine.ear"."root.war"

Hi I installed Ovirt and i set up two virtual machine and it was working very good. then i try to use spice activeX on IE and i changed web.xml file as said on this link: http://wiki.ovirt.org/How_to_Connect_to_SPICE_Console_With_Portal then i restart jboss-as and ovirt-engine and everything was true. then i restart the server and i see some errors on server.log under ovirt-engine dir. and in apache ssl_log i saw this error: "GET / HTTP/1.1" 404 - I attached the server.log. the main error is: 2012-12-02 20:30:33,511 ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) {"JBAS014653: Composite operation failed and was rolled back.
