如何在不执行注销和登录操作的情况下获取更新的值？

Question

我正在处理注册表格，这里一切正常。但是，我有一个小问题。当我在表单中编辑时，表单的值将在数据库中更新。但是，当我观看我的个人资料时，它仍然只显示旧值。然后，如果我尝试注销，再次登录页面，我正在查看新的值显示在我的个人资料中。那么，可能是什么问题呢？如何在不执行注销和登录操作的情况下获取更新的值？提前谢谢..

编辑细节的servlet代码：

if(formIdentity.equalsIgnoreCase("editdetails"))
{
    if (checkboxStatus.equalsIgnoreCase("No"))
    {
    User user=new User();
    System.out.println("in datafile con of  servlet...");
         try
         {
         user.setId(Long.parseLong(request.getParameter("userid")));
         user.setFirstName(request.getParameter("fname"));
         user.setLastName(request.getParameter("lname"));
         user.setLocation(request.getParameter("location"));
         user.setDateofbirth(request.getParameter("dob"));
         user.setEmail(request.getParameter("email"));
         user.setDesc(request.getParameter("desc"));
         user.setProfession(request.getParameter("profession"));
         user.setProjects(request.getParameter("myprojects"));  
         user.setHobbies(request.getParameter("hobby"));
         System.out.println("in try con of  servlet...");
         userDao.updateUser(user);
         response.sendRedirect("Home");
         }          
         catch(Exception e1)
         {
        e1.printStackTrace();
         }
         finally
         {
            userDao.closeSession();
         }
         }
         else if(checkboxStatus.equalsIgnoreCase("Yes"))
         {
         mpr=new MultipartRequest(request,webTempPath,5*1024*1024, new MnthFileRenamePolicy());
         response.setContentType("text/html");
         System.out.println("inside editdetails..");
         try
            {
         System.out.println("in datafile con of  servlet...");
         this.filename=mpr.getFilesystemName("datafile");
         File srcFile=new File(webTempPath+this.filename);  
         mpr.copyFile(srcFile, new File(webTempPath+"signup/"+this.filename));
         String imgpath="assets/signup/"+this.filename;
         System.out.println("image is=="+imgpath);
         System.out.println("After file of  servlet...");
         User user=new User();
         user.setId(Long.parseLong(mpr.getParameter("userid")));
         user.setFirstName(mpr.getParameter("fname"));
         System.out.println("After fname of  servlet..."+mpr.getParameter("fname"));
         user.setLastName(mpr.getParameter("lname"));
         user.setLocation(mpr.getParameter("location"));
         user.setDateofbirth(mpr.getParameter("dob"));
         user.setEmail(mpr.getParameter("email"));
         user.setProfession(mpr.getParameter("profession"));
         user.setHobbies(mpr.getParameter("hobby"));
         System.out.println("After email of  servlet..."+mpr.getParameter("email"));
         user.setDesc(mpr.getParameter("desc"));
         user.setImagePath(imgpath);
         userDao.updateUser(user);
         response.sendRedirect("Home");
        }
    catch(Exception e1)
            {
        e1.printStackTrace();
        }
            finally
        {
    userDao.closeSession();
    }
