jsp) 자바빈으로 값 전달이 안 되고 null로 뜨는 문제

이런 식으로 됩니다. join.jsp에서 회원가입 정보를 작성하고 등록 버튼을 누르면 join_process.jsp로 이동하는 방식입니다.

joinBean.java와 joinBean.class 파일은 [톰캣경로/webapps/java_web_last/WEB-INF/classes/com/test]에 있고 다른 jsp 파일은 [톰캣경로/webapps/java_web_last]에 있습니다.

vscode로 작업하고 있구요, 위치가 잘못된 걸까요? 뤼튼에 물어볼 때마다 코드는 문제가 없다고 뜨거든요.

코드도 함께 첨부합니다. 잘 아시는 분들 도움 부탁드립니다. ㅠㅠ

null로 표시되는 것 말고 따로 오류 뜨는 건 없습니다. 자바빈 파일이 연결이 안 되는 것 같은데...
