(icon?,display-name?,description?,distributable?,context-param*,filter*,filter-mapping*, listener*, servlet*,servlet-mapping*, session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*, resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*, ejb-local-ref*)
