Apache 서버의 Tesseract : 프로세스가 다른 프로세스에서 사용 중이기 때문에 프로세스가 파일에 액세스 할 수 없습니다.

Question

JSF 웹 응용 프로그램에서 Tesseract를 사용하고 있습니다. 나는 아파치 톰캣 7 서버를 사용하여 내 웹 프로젝트에 통합하면 나는 간단한 자바 프로젝트와 정팔 포체의 API에 익숙해지고 있다고

는 그 다음 문제없이 일했다, 나는 다음과 같은 예외가 얻을 :

여기 내 호출하는 방법입니다 :

/** 
* Reading PDF and images with Tesseract OCR 
* @param filePath 
* @return content 
*/ 
public String OCR(String filePath) 
{ 
    String content = null; 

    File imageFile = new File(filePath); 

    Tesseract ins = new Tesseract(); 
    ins.setDatapath("../tessdata"); 

    try { 
     content = ins.doOCR(imageFile); // <-- Exception thrown from here 

    } catch (TesseractException e) { 

     System.err.println(e.getMessage()); 
    } 

    return content; 
} 

이 screenshot에서 볼 수있는 바와 같이, DLL이 존재하고, 내 웹 응용 프로그램은 정팔 포체를 사용하는 유일한 응용 프로그램입니다, 그래서 정말이를 사용하는 과정을 모르는 도서관 ... 어떤 아이디어 제발!

Answer 1

글쎄, 나는 서버를 계속 실행하고 그냥 프로젝트를 재구성하는 대신에 tesseract가 처음으로 나온 후에 dll을 해제하지 않은 서버 자체이기 때문에 항상 서버를 다시 시작해야한다고 생각했다. 라는.

희망이 미래

PS에서 사람을 도움이 될 것입니다 : 내가 IntellijIdea을 사용하고 있습니다.
