我想在Eclipse中使用Servlet进行开发,但它说javax.servlet无法解析包.如何将javax.servlet包添加到Eclipse项目中？

我收到以下错误:

我放置JARS WEB-INF/lib.这是项目类路径的样子:

这是运行配置:

添加FileUpload后麻烦开始了.
知道什么是错的吗？

正在开发一个简单的文件上传程序。我必须使用 jakarta.servlet.* 类，因为我使用的是 Tomcat v10。我在 parseRequest(request) 行收到编译时错误。

代码 ：

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        ServletFileUpload sf = new ServletFileUpload(new DiskFileItemFactory());
        try {
            List<FileItem> multifiles = sf.parseRequest(request);
            
            for(FileItem i : multifiles) {
                i.write(new File("C:/Users/Luffy/Documents/FileUploadDemo/"+i.getName()));
            }
            response.getWriter().print("The file is uploaded");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
        response.getWriter().print("The file is uploaded");
    }

错误如下：

ServletFileUpload 类型中的方法 parseRequest(javax.servlet.http.HttpServletRequest) 不适用于参数 (jakarta.servlet.http.HttpServletRequest)

我在谷歌上搜索了很多但找不到解决方案。

请提出解决方法或可能的解决方案。提前致谢。

这是我在 Stack Overflow 上的第一篇文章。所以请忽略我的错误（如果有的话）：）
