this also happened to me. but when i set UseJBossWebLoader=true but now my backing bean dosen't find the ajax4jsf.jar and richfaces.jar in my WEB-INF\lib folder, and fails to deploy. It fails when it has to to call processDrop with org.ajax4jsf.dnd.event.DropEvent argument. I tried to put the jars in the server/deploy/lib but now it gets | 2007-04-23 16:04:21,090 WARN [org.apache.myfaces.config.FacesConfigurator] More than one managed | bean w/ the name of 'a4j' - only keeping the last | 2007-04-23 16:04:21,090 WARN [org.apache.myfaces.config.FacesConfigurator] More than one managed | bean w/ the name of 'a4jSkin' - only keeping the last | 2007-04-23 16:04:21,090 WARN [org.apache.myfaces.config.FacesConfigurator] More than one managed | bean w/ the name of 'ajaxContext' - only keeping the last | when i deploy the first time it works fine. but when i redeploy the time stamp on the jar in WEB-INF/lib change and if i don't copy them againg to server/deploy/lib i get: javax.servlet.ServletException: loader constraints violated when linking org/ajax4jsf/dnd/Draggable class | my question is how can i get around this?
