線程「AWT-EventQueue-0」中的異常java.lang.NoClassDefFoundError

我試圖將.docx文件讀入JTextPane，但它給出了一些例外。我正在使用POI庫。我該怎麼辦？請幫助我。這裏是我的代碼：線程「AWT-EventQueue-0」中的異常java.lang.NoClassDefFoundError

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);

這是Exception：

看起來你缺少一個依賴庫 – MadProgrammer 2013-05-04 09:46:27

我使用所有的庫從POI。 – 2013-05-04 09:48:15

看來你需要[XMLBeans]（http://xmlbeans.apache.org/）。這可能是一個子項目的要求。 Apache POI有一個Maven條目。你可以加載它，並允許Maven整理出來 – MadProgrammer 2013-05-04 09:50:10

除了apache-poi JAR文件，例如，

 
    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

您還需要在JAR來自ooxml-lib的文件在您的classpath：

 
    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

我試過你的第二個建議，但我顯示喬達時間錯誤，然後我添加喬達時間瓶。現在它顯示java.lang.ExceptionInInitializerError錯誤。其實問題是什麼。 – Thirunavukkarasu 2015-09-07 11:06:57

我改用'java.time'，引用[here]（http://stackoverflow.com/q/24631909/230513）。 – trashgod 2015-09-07 17:02:36
