我正在使用 apache poi 从 doc ， docx 等各种文档文件中提取文本。我的代码在 Windows 中运行良好，但在部署到测试服务器之后它无法运行。
服务器操作系统：Amazon Linux 环境：AWS
这是我的代码段：
if(extension.equals("docx")){
XWPFDocument document = new XWPFDocument(new FileInputStream(resume));
XWPFWordExtractor we = new XWPFWordExtractor(document);
resumeAsText = we.getText();
} else if(extension.equals("doc")){
Word6Extractor extractor = new Word6Extractor(new FileInputStream(resume));
resumeAsText = extractor.getText();
} else if(extension.equals("pdf")){
PDFParser parser = new PDFParser(new FileInputStream(resume));
parser.parse();
COSDocument cosDoc = parser.getDocument();
PDFTextStripper pdfStripper = new PDFTextStripper();
PDDocument pdDoc = new PDDocument(cosDoc);
resumeAsText = pdfStripper.getText(pdDoc);
cosDoc.close();
pdDoc.close();
} else if(extension.equals("rtf")){
RTFEditorKit rtfParser = new RTFEditorKit();
Document document = rtfParser.createDefaultDocument();
rtfParser.read(new FileInputStream(resume), document, 0);
resumeAsText = document.getText(0, document.getLength());
}
我收到此错误：
