Tomcat에서 net.sourceforge.jtds.jdbc.Driver를로드 할 수 없습니다.-다시

Tomcat에서 net.sourceforge.jtds.jdbc.Driver를로드 할 수 없음 과 동일한 오류 이지만 이번에는 해당 솔루션이 작동하지 않습니다. FreeBSD 10 서버에서 Tomcat 8.0.9에서 8.0.12로 업데이트를 완료했으며 jtds jar가 lib 폴더에 있더라도 다시 한 번 해당 오류를 수신하고 있습니다. 이전 버전이 손상되었을 경우를 대비하여 jtds의 새 복사본을 다운로드하고 WAR (경우에 따라)도 재배포했습니다. 변경 없음. 분명히 Tomcat 8.0.9로 롤백하는 것이 해결 방법이지만 작업 할 시간이 있고 서버 소프트웨어에 대한 최신 정보를 유지하는 것이 현명합니다.이 오류가 다시 발생하는 이유에 대한 아이디어 그리고 그것을 해결하는 방법?
