Question

我使用Apache POI来读取.doc文件。如果.doc文件包含图像，则代码最终会出现异常。没有图像的文件可以成功读取并输出。

我的代码如下。

File file = null;
WordExtractor extractor = null ;
String res="";
try 
{
    file = new File("E:\\MCA\\S5\\Mini Project\\trial.doc");
    FileInputStream fis=new FileInputStream(file.getAbsolutePath());
    HWPFDocument document=new HWPFDocument(fis);
    extractor = new WordExtractor(document);
    String [] fileData = extractor.getParagraphText();
    for(int i=0;i<fileData.length;i++)
    {
    fileData[i]=fileData[i].trim();
    out.println(fileData[i]);            
    }
 }

catch(Exception exep)
{
    out.println(exep.getMessage());
}

该异常在

处触发

HWPFDocument document=new HWPFDocument(fis);

例外：

  org.apache.jasper.JasperException: An exception occurred processing JSP page /word_read.jsp at line 23

20: {
21:     file = new File("E:\\MCA\\S5\\Mini Project\\trial.doc");
22:     FileInputStream fis=new FileInputStream(file.getAbsolutePath());
23:     HWPFDocument document=new HWPFDocument(fis);
24:     extractor = new WordExtractor(document);
25:     String [] fileData = extractor.getParagraphText();
26:     for(int i=0;i<fileData.length;i++)

如果文件包含图像，Apache POI会显示异常
