我的服务器端是一个 JSP 应用程序，它托管在 Appache Tomcat 7（Eclipse 中的插件）上。我的客户端是：-

if(("GET").equalsIgnoreCase(request.getMethod())&&("Create Reimbursement").equalsIgnoreCase(request.getParameter("Create Reimbursement"))){ 
//crresult = lmktweb.createReimbursement(Integer.parseInt(request.getParameter("ID")), request.getParameter("EmpdID"), request.getParameter("DateCreated"), request.getParameter("Amount"),request.getParameter("Vendor"),request.getParameter("picpath"));
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://192.168.80.125:8080/UploadFileServerSide/UploadHandler.jsp");
MultipartEntity entity = new MultipartEntity();
System.out.println(request.getParameter("fname"));
if(request.getParameter("fname")!=""){
    File file = new File(request.getParameter("fname"));
    entity.addPart("data", new FileBody(file));
    httppost.setEntity(entity);    
    HttpResponse resp = httpclient.execute(httppost);
}

我的服务器端是： -

try {
                        String itemName = item.getName();
                        String fpath = "";
                        //item.
                        File root=File.listRoots()[0];
                        String extPath;
                        if(crdate!=""){
                            extPath = rei.HandlePathWithDate(crdate,getServletContext().getRealPath("images"));
                            fpath = extPath+"\\"+ppath;
                            fpath = extPath.replaceAll("/", "\\");
                        }   
                        else{

                            extPath= getServletContext().getRealPath("/");
                            fpath = extPath.concat("\\"+itemName);                              
                            fpath = extPath.replaceAll("/", "\\");                          

                        }
                        System.out.println("Saving as: " +fpath);
                        File f = new File(fpath);

                        f.setWritable(true);
                        f.setReadable(true);
                        item.write(f);

                    } catch (Exception e) {
                        e.printStackTrace();
                        response.setHeader("Error", e.getMessage());                            
                    }

但是在给定路径上写入文件时会产生以下错误：-

另存为：D:\Z-Main\Projects\Android Projects.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\UploadFileServerSide\ java.io.FileNotFoundException: D:\Z-Main\Projects\ Android

哪里有问题。我目前正在使用 Tomcat Eclipse 插件，控制台上出现此错误。我在 android 应用程序中调用相同的代码，它工作正常。请提供有用的详细信息。我试图编辑位于 eclipse 服务器插件文件夹中的 catalina.policy 文件并添加了以下行：-

grant codeBase " file:${catalina.base}/webapps/UploadFileServerSide/-" {
  ermission java.io.FilePermission "${tomcat.home}/-","read,write"; };

并从 Eclipse 重新启动服务器，期待不同的结果，但到目前为止还没有运气。我在哪里迷路了？

当我使用 Servlet 而不是 JSP 并在提交页面时使用 POST 方法时，问题得到了解决。奇怪的！！！！因为其余的东西几乎是一样的。仍然困惑为什么会发生，因为我认为 Servlet 在服务器上具有与 JSP 相同级别的访问权限。可能是我的假设是错误的！
