我收到了以下错误

Order.com.MainMethod.main(MainMethod.java:71)中的订单"."主"java"中的异常java.lang.NoClassDefFoundError:org/apache/xmlbeans/XmlObject在OrderBook.WriteToExcelSheet.CreateOutPutFile(WriteToExcelSheet.java:20)

我在网上查找了这个错误的原因,但无法找到我收到它的原因.

我已经包含了以下jar文件

poi-3.9-20121203.jar, 
poi-excelant-3.9-20121203.jar,
poi-examples-3.9-20121203.jar,
poi-ooxml-3.9-20121203.jar,
poi-ooxml-schemas-3.9-20121203.jar,
poi-scratchpad-3.9-20121203.jar

码:

public class WriteToExcelSheet {
    public static Map < Integer, Object[] > data = new TreeMap < Integer, Object[] > ();
    public static void CreateOutPutFile() {
        XSSFWorkbook workbook = new XSSFWorkbook();
        XSSFSheet sheet = workbook.createSheet("Orderbook Stats");
        //This data needs to be written (Object[])
        //Iterate over data and write to sheet
        Set < Integer > keyset = data.keySet()
        int rownum = 0;
        for (Integer key: keyset) {
            Row row = sheet.createRow(rownum++); …

为了读取xlsx我正在使用apache POI 的文件,我已经下载了zip并将以下jsrs放在我的servlet位置webcontent/web-inf/lib并通过eclipse配置了构建路径

我的代码如下,

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

File uploadedFile = new File(fpath, fileName);
item.write(uploadedFile);
String mimeType = (Files.probeContentType(uploadedFile.toPath())).toString();
System.out.println(mimeType);
if(mimeType.equals("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"))
{
FileInputStream file = new FileInputStream(uploadedFile);
    XSSFWorkbook workbook = new XSSFWorkbook(file);
    for (int i =0; i < workbook.getNumberOfSheets(); i++)
    {
       XSSFSheet sheet = workbook.getSheetAt(i);
       Iterator<Row> row = sheet.iterator();
       while(row.hasNext()) {
   Iterator<Cell> cellIterator = ((Row) row).cellIterator();
       while(cellIterator.hasNext()) {
       Cell cell1 = cellIterator.next();
       switch(cell1.getCellType()) 
         {
    case Cell.CELL_TYPE_BOOLEAN:
    System.out.print(cell1.getBooleanCellValue() + "\n");
    break;
    case Cell.CELL_TYPE_NUMERIC: …
