JDBC 드라이버

상황 :JDBC 드라이버

내가 PostgreSQL을 9.1을 사용하고 있는데 지금은 데이터베이스에 저장된 데이터웨어 하우스에서 보고서를 만들 펜타 보고서 디자이너를 사용하고 있습니다. 이 데이터베이스의 이름은 bd-datawarehouse입니다.

내가 가지고있는 문제는 Pentaho 보고서 디자이너에서 bd-datawarehouse 데이터베이스로의 연결을 만들려고 할 때의 문제입니다. 나는 모든 설정을 구성한 모든 것이 다음 이미지처럼, 올바른 보인다

하지만 난 Test 버튼을 클릭하면, 그것은 나에게 다음 오류 제공 :

Error connecting to database [conexion-dw-reporting] : org.pentaho.di.core.exception.KettleDatabaseException: 
Error occured while trying to connect to the database 

Exception while loading class 
org.postgresql.Driver 


org.pentaho.di.core.exception.KettleDatabaseException:

을 모든 설정 필드가 올바른지 (데이터베이스 이름, 포트 번호, 호스트 이름, 사용자 이름 및 암호) 알고 있어야합니다.

오류를보고 나는 문제가 내가 PostgreSQL 데이터베이스를 연결하는 jdbc 드라이버가 아니기 때문에 내가 그것을 찾았고 this question의 수락 된 응답처럼했을 것이라고 생각했다. : 내 postgresql 9.2에 대한 드라이버를 here에서 다운로드했는데 ...\biserver-ce\tomcat\lib\에 넣었지만 문제가 지속됩니다.

문제를 너무 깊이 이해하지 못하기 때문에 해결 방법을 모르겠습니다.

도움이 될 것입니다.

excepion'java.lang.ClassNotFoundException' 분명히 잘못된 디렉토리에 jar 파일을 넣어 나타냅니다. 당신의 스크린 샷은 Swing GUI에서 나온 것 같지만, 드라이버를 Tomcat 디렉토리에 넣었다고 명시하고 있습니다. Swing GUI가 Tomcat 설치 라이브러리를 사용하는 것은 의심 스럽습니다. –

마스터! 나는 잘못된 폴더 안에 드라이버를 넣고 있었다. 난 그저 오른쪽 폴더로 이동하고 내 문제를 해결합니다. 답으로 의견을 말하십시오. 도움을 주셔서 감사드립니다. – carexcer

보고서 디자이너 \ lib 디렉토리의 \의 JDBC는

\ 또는 BD-데이터웨어 하우스 \ lib 디렉토리의 \ JDBC를 \ 당신은 위의 경로에 대한 적절한 JDBC jar 파일을 배치해야합니다. 그런 다음 pentaho보고 도구를 다시 시작해야합니다. 그것은 일할 수도 있습니다. 나를 위해 일하고.
