根据JSP文件内容更新HTML文件(Update HTML file based on JSP file contents)

 我有一个JSP文件，其中包含一个包含以下输入类型的表单：密码字段和2个文本输入字段。 此页面仅对主持人可见，以便主持人可以输入密码，然后才能修改任何内容。 主持人修改内容后，更新的内容将被写入文本文件，然后从文本文件中提取内容并放在div上供主持人查看。 这是一个jsp文件。 这是我的文件阅读器部分的代码： 
 
<%
    String file = "/docs/file.jsp";
    FileReader read = new FileReader(file);
    Scanner scanner = new Scanner(read);
    scan.useDelimiter("\n");
    ArrayList<String> list = new ArrayList<String>();

    while(scanner.hasNext()){
      list.add(scan.next());

     for(int i=(list.size()-2); i<list.size(); i++)
    {
       %>
         <div id="contact"> <%=list.get(i)%> </div> <%
      }
     scanner.close();
 } %>
 
 我有一些.html文件，我想在主持人做出更改后立即更新。 例如，如果她更改了公司电话号码和传真号码，我希望在“联系我们”页面，“关于”页面等中自动显示更改.html文件如下所示： 
 
<div>
<p> 1-800-888-8888 </p>
</div>
 
 我知道如果我包含一个链接到.jsp文件的href标签，输入字段将对用户可见，这是我不想要的。 我只是希望他们在网站上看到更新的电话号码。 我是否必须在.html文件中包含我的.jsp文件中的“contact”div？ 如果是这样，我将如何做到这一点？ 任何帮助，将不胜感激。 

I have a JSP file which includes a form with the following input types: a password field, and 2 text input fields. This page will only be visible to a moderator so that the moderator may type in the password and only then will she be able to modify any contents. After the moderator modifies the contents, the updated contents will be written to a text file, and then the contents are extracted from the text file and placed on a div for the moderator to view. This is all in one jsp file. Here is my code for the file reader portion:
 
<%
    String file = "/docs/file.jsp";
    FileReader read = new FileReader(file);
    Scanner scanner = new Scanner(read);
    scan.useDelimiter("\n");
    ArrayList<String> list = new ArrayList<String>();

    while(scanner.hasNext()){
      list.add(scan.next());

     for(int i=(list.size()-2); i<list.size(); i++)
    {
       %>
         <div id="contact"> <%=list.get(i)%> </div> <%
      }
     scanner.close();
 } %>
 
I have a few .html files that I would like to update as soon as the moderator makes changes. For example, if she changes the business phone number and fax number, I want the changes to be visible automatically in the Contact Us page, About page, etc. The html file looks like this:
 
<div>
<p> 1-800-888-8888 </p>
</div>
 
I know that if I include an href tag linking to the .jsp file, the input fields will be visible to the users, which I don't want. I just want them to see the updated phone numbers all around the site. Would I have to include the "contact" div from my .jsp file in the .html file? And if so, how would I go about doing that? Any help would be appreciated.
