过去一周我一直在从事一个工作项目，但由于不断收到错误，我陷入了困境。我想知道是否有人可以帮助我。
我已附上我创建的两个文件以及我收到的错误。如果有人能告诉我如何修复该错误，我将不胜感激
我正在使用 eclipse 并附加了所有最新的 jar 文件(xmlbeans2.6、poi-scratchpad 3.13beta、poi-ooxml-schemas 3.13beta、poi-ooxml-3.13beta 和 poi-3.13 beta)
第一个类创建一个用户可以与之交互的界面。首先你打开一个Excel文件。然后通过点击分类按钮，它应该调用第二类。第二节课将读取 Excel 文件并显示其内容。截至目前，如果我将调用函数更改为 readxlsfile 函数，它就可以完美运行。当我尝试调用 readxlsxfile 时出现问题。我收到以下错误
如果可能的话，谁能帮我找到一种方法，根据所选的 Excel 文件自动选择正确的函数。

最佳答案
我相信您已将其配置为使用相同版本的 POI，但我仍然认为旧版本正在从某处泄漏到您的类路径中。以下代码取自the POI FAQs ;请绝对确定以下所有三个输出均符合您的预期。
ClassLoader classloader =
org.apache.poi.poifs.filesystem.POIFSFileSystem.class.getClassLoader();
URL res = classloader.getResource(
"org/apache/poi/poifs/filesystem/POIFSFileSystem.class");
String path = res.getPath();
System.out.println("POI Core came from " + path);
classloader = org.apache.poi.POIXMLDocument.class.getClassLoader();
res = classloader.getResource("org/apache/poi/POIXMLDocument.class");
path = res.getPath();
System.out.println("POI OOXML came from " + path);
classloader = org.apache.poi.hslf.HSLFSlideShow.class.getClassLoader();
res = classloader.getResource("org/apache/poi/hslf/HSLFSlideShow.class");
path = res.getPath();
System.out.println("POI Scratchpad came from " + path);
