线程“AWT-EventQueue-0”中出现异常java.lang.NoClassDefFoundError

Question

我正在尝试将. docx文件读取到JTextPane中，但它提供了一些异常。我正在使用POI库。我该怎么办？请帮帮我。这是我的代码：

file = new File(
    "C:\\Users\\Siddique Ansari\\Documents\\CV Parser\\Siddique_Resume.docx");
FileInputStream fis=new FileInputStream(file.getAbsolutePath());
XWPFDocument document=new XWPFDocument(fis);// line no 549
extractor = new XWPFWordExtractor(document);
String fileData = extractor.getText();
Document doc = jTextPane1.getDocument();      
System.out.println(fileData);
doc.insertString(doc.getLength(), fileData, null);

这是例外情况：

除了apache poi JAR文件之外，

  1869113  11-26-12 17:22   poi-3.9/poi-3.9-20121203.jar
   936648  11-26-12 17:22   poi-3.9/poi-ooxml-3.9-20121203.jar
  4802621  11-26-12 17:22   poi-3.9/poi-ooxml-schemas-3.9-20121203.jar

您还需要在类路径中使用 ooxml-lib 中的 JAR 文件：

   313898  04-05-09 14:28   poi-3.9/ooxml-lib/dom4j-1.6.1.jar
    26514  02-23-11 12:31   poi-3.9/ooxml-lib/stax-api-1.0.1.jar
  2666695  04-05-09 14:29   poi-3.9/ooxml-lib/xmlbeans-2.3.0.jar
