Question

我正在用Java编写一个应用程序，它使用JexcelAPI创建一个Excel 2003文件，将数据写入其中（17列，15,000行）。从可靠的数据流接收数据。到目前为止一切都很好 - 它完美无缺。当我试图在某些单元格中放置超文本时（实际上在一列中），问题就出现了。从这一刻起，文件保存失败。代码：

public class partsData 
{
   private final static String PdbFileName = "partsDB.xls";
   private static WorkbookSettings PdbWorkSheet = null;
   private static WritableWorkbook PdbWorkbook = null;
   private static WritableSheet PdbWritableSheet = null;

   WritableHyperlink wh = null;

   public static void main (String args[])
   {
      Int linesCounter = 2;
      try 
      { 
         PdbWorkSheet = new WorkbookSettings();
         PdbWorkbook = Workbook.createWorkbook(new File(PdbFileName), PdbWorkSheet);
         PdbWritableSheet = PdbWorkbook.createSheet(PdbFileName, 0);
      } 
      catch (IOException e) { filesClose("File open failed - program aborts\n"); }

      try 
      { // Write to the cells
        lr = new Label(10, linesCounter, splitLine[0]);
        PdbWritableSheet.addCell(lr);
    }
        catch (WriteException e) { logFileWrite("Write failure - #" + linesCounter); }

// Create hyperlink fields based on the data already embedded in the Excel
       String sStr = <File name and path>
       String tStr = <field text>

       if ((sStr != "") && (tStr != "") && (linesCounter > 1))
       {
         file = new File (sStr);
            wh = new WritableHyperlink(4, linesCounter, file);
         try { PdbWritableSheet.addHyperlink(wh); }
         catch (RowsExceededException e) { logFileWrite("REE); }
         catch (WriteException e) { logFileWrite("WE); }
       }
       else
         logFileWrite("No hyperlink");
      }

      try
      {
         PdbWorkbook.write();  // This is where the exception occurs
         PdbWorkbook.close();
      }
      catch (IOException | WriteException e) { logFileWrite("close failure); };
      logFileWrite(message);         
   }
}

错误消息：

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 1
    at java.lang.String.charAt(Unknown Source)
    at jxl.write.biff.HyperlinkRecord.getFileData(HyperlinkRecord.java:1011)
