apache resin personal oracle 을 이용해서 공부중입니다.

resin.conf에 다음과 같이 설정했습니다.


jdbc/test
javax.sql.DataSource








이상태에서 jsp 화일을 돌리면 다음과 같은 에러가 나옵니다.

이것은 classes12.zip 화일이 클래스패스에 없어서 나온다고 그러는데 저의 classpath값은 다음과 같이 설정되어 있습니다.

.;C:\esin-2.1.4\\lib\\classes.zip;C:\esin-2.1.4\\lib\\classes12.zip;C:\\j2sdk1.4.1_01\\lib\\tools.jar;C:\\j2sdk1.4.1_01\\lib\\dt.jar


클래스 패스도 잡어줬는데 계속해서 이렇게 에러메세지가 나오는 이유를 모르겠습니다. 
답변 부탁드립니다.

오라클 jdbc driver classes12.zip을 
$RESIN_HOME/lib에 넣어 놓으셨으면
CLASS_PATH에서는 그것을 제거하세요.
$RESIN_HOME/lib에 있는 .jar를 파일은
Resin에서 CLASS_PATH와 관계없이 
공통으로 사용가능합니다.

$RESIN_HOME/bin/httpd.sh -verbose 로 실행하셔서
CLASS_PATH를 확인해 보세요.
