Answer 1

데이터베이스 연결을 얻기 전에 Class.forName()을 호출하여 수동으로 드라이버 클래스를로드 해보십시오. 예를 들어, MySQL 데이터베이스를 사용하는 경우 데이터베이스 연결을 가져 오기 위해 문 위에 다음 문을 추가하십시오.

Answer 2

다음 단계를 사용하여 클래스 경로에 데이터베이스 드라이버 (JAR (s))를 추가하십시오. 이렇게하면 문제가 해결됩니다.

1. Select your project from the Projects explorer. 
2. Right click -> Properties. 
3. Select Libraries from Categories list. 
4. Click on Add JAR/Folder button. 
5. Add your jar(s) & click on OK to finish the process.
