여타 설정은,
의 DBCP구성을 따라 했습니다. (일단은요...)
음, 샘플 페이지를 구성해서 열때,
2-3번에 한번씩은
하기와 같은 에러를 뱉어내는데요...

혹시 원인이 뭔지 알수 있을까요?
100% 어떤상황이다 까진 아니어도 iBATIS 를 붙였을때 "Attempt to access a closed PreparedStatement." 에러를 뱉어낼때는 ~~~~러한 이유때문일수 있다..
라는것 만이라도 좀...
감사합니다, 좋은 하루들 되셔요.
일반적으로 발생할 수 있는 에러는 commit/rollback 이 수행된후 preparedstatement 를 통한 execution 이 발생시 발생할 수 있는 에러입니다. CUBRID는 commit/rollback을 수행하면 열려져 있던 connection을 제외한 모든 데이터베이스 관련 정보가 닫힙니다. 혹은 prepare 과정에서 에러가 있었는데 이를 놓쳐서 발생할 수도 있을 것입니다.
따라서 소스상에서 에러처리와 commit/rollback 후 다시 prepare 가 되고 있는지를 확인해 보시면 될 것 같습니다.
