我的myApplication.jsp结构是这样的:
A list of entries in the system
A form with textboxes that submits new entries.

index.jsp:
Hashcode of request object in main page: <%= request.hashCode() %>
<%@ include file="includedirective.jsp"%>
<jsp:include page="includeaction.jsp" />
includeDirective.jsp:
Hashcode of request object in include directive: <%= request.hashCode(

<%@ include file="header.jsp" %>
<%
//code here to check user login

request.setAttribute("results",returneddocs);
rd.forward(request, response);
// Now, I am ab
在一个项目中,我使用一个文件来读取数据,例如,当我启动一个研究时,我的jsp页面被加载了,但是文件还没有刷新,我得到了旧的结果。我必须手动重新加载表格中的数据。在装入jsp之前,我不知道如何刷新文件。
// research
FileWriter fileJSON;
try {
fileJSON = new FileWriter("C:\\Users\\.....\\myFile");
fileJSON.write(array.toString()); //array is a JSONArray containing
