Thank you for your quick reply. I don't have any jar file in the workspace - I guess that the jar is created during the deplyoment to the server's "deploy" directory. Anyway, the problem happens also after restarting (Eclipse & machine). For some reason, EJB client project is deployed as a jar file, but the EJB project itself (beans implementation) is deployed as group of flat files... maybe this is the root of the problem?
