【问题描述】：
您好，我想使用 Apache POI 库向网页显示 Microsoft 文档内容
这作为 java 应用程序运行良好。
但应用程序在 jsp 上抛出异常
PS
以下是我目前的工作
<%@ page import="java.io.*" %>
<%@ page import="org.apache.poi.openxml4j.opc.OPCPackage" %>
<%@ page import="org.apache.poi.xwpf.extractor.XWPFWordExtractor" %>
<%@ page import="org.apache.poi.xwpf.usermodel.XWPFDocument" %>
<body>
<form name="form1" method="get" action="FileServlet"
style="height: 78px;">
<input type="file" name="xls_filename" align="top"
onchange="form1.submit()">
</form>
<%
String filename = request.getParameter("xls_filename");
if (filename != null && !filename.equals("")) {
%>
<br>You chose the file
<%=filename%>.
<br>It's contents are:
<%
InputStream fs = null;
String fileData;
XWPFWordExtractor extractor = null;
try {
fs = new FileInputStream(filename);
XWPFDocument hdoc = new XWPFDocument(OPCPackage.open(fs));
extractor = new XWPFWordExtractor(hdoc);
fileData = extractor.getText();
System.out.println(fileData);
// document.add(new Paragraph(fileData));
System.out.println(" pdf document created");
} catch (IOException e) {
System.out.println("IO Exception");
e.printStackTrace();
} catch (Exception ex) {
ex.printStackTrace();
} finally {
// document.close();
}
%>
<%
}
%>
</body>

上面是完整的堆栈跟踪和错误显示为：
jsp文件中的第40行发生错误：/index.jsp XWPFDocument 无法解析为类型
jsp文件中的第40行发生错误：/index.jsp 无法解析 OPCPackage
jsp文件中的第42行发生错误：/index.jsp XWPFWordExtractor 无法解析为类型
【问题讨论】：
-
显示完整的堆栈跟踪。
-
这是完整的堆栈跟踪吗？
-
@Mubin 编辑我的完整堆栈跟踪
-
这个 java 代码作为一个 java 应用程序工作
-
是的，将 jar 添加到 lib 文件夹对我有用，谢谢
