Olá pessoal, estou tentando ler um arquivo de imagem que foi transformado em OCR com o ABBYY, estou utilizando a API PDFBox para fazer a leitura.
O código é:
public static String lerPDF(String aARQUIVO) throws IOException{
PDFTextStripper stripper = new PDFTextStripper();
PDDocument pdDoc = PDDocument.load(aARQUIVO);
StringWriter writer = new StringWriter();
stripper.writeText(pdDoc, writer);
return writer.toString();
}
Estou obtendo o seguinte erro:
