JSP包含页面不起作用 [英] JSP include page doesn't work

问题描述

我有一个JSP文件，member.jsp如下：

 <％@ page import =java .util。*％> 
< jsp：include page =/ html_functions.jsp/> 
 
<％String heading =Header％> 
<％= formStart（a_form）％> 
<％= printPageHeader（heading）％> 
<％= startMyLi（）％> 
<％= endLi（）％> 
<％= formEnd（）％> 
  

和我的html_functions.jsp如下：

 <％！ 
 
 public String formStart（String name）{
 String structure =< div id = \content \>< form name = \+ name + \method = \post \>< ul>; 
返回结构; 
} // formStart 
 
 public String printPageHeader（String name）{
 String structure =< li class = \listLi \> \ n< h3 class = \formHeader \> + name +。< / h3>< / li>; 
返回结构; 
} // printPageHeader 
 
 public String startMyLi（）{
 String structure =< li class = \listLi \>; 
返回结构; 
} // startMyLi 
 
 public String endLi（）{
 return（< / li>）; 
} // endMyLi 
 
 public String displayWithSpan（String str）{
 String structure =< span class = \labelSpan \> + str +< / span>; 
返回结构; 
} // displayWithSpan 
 
 public String displayInputElement（String name）{
 return（Hiiiii）; 
} // displayInputElement 
 
％> 
  

但是，我在调用member.jsp文件时遇到异常。这是我得到的例外：

  org.apache.jasper.JasperException：无法为JSP编译类：
 
 jsp文件中的行：xx发生错误：/ member.jsp 
类型add_005fmember_jsp 
   
 
 
所有其他方法都是如此。我在哪里弄错了？
 
 
 
谢谢
解决方案
使用
 <％@ include file =/ html_functions.jsp％> 
  
工作正常而不是< jsp：include page =html_functions.jsp />  
 
 
 
有两种方法可以将文件包含在应用程序的JSP页面中。具体如下：
 
 
 <％@ include file =relativeURL％>  
 
 
 < jsp：include page =relativeURL/>  
 
 
 第一种情况包括编译时调用JSP文件中文件或文本或文件代码，稍后执行。

并检查html_functions.jsp是否放置在正确的路径中。
 
I have a JSP file, member.jsp which is as follows :
<%@ page import="java.util.*" %>
<jsp:include page="/html_functions.jsp" />

<% String heading = "Header" %>
<%= formStart("a_form") %>
<%= printPageHeader(heading) %>
<%= startMyLi() %>
<%= endLi() %>
<%= formEnd() %>
and my html_functions.jsp is as follows :
<%!

public String formStart(String name) {
    String structure = "<div id=\"content\"><form name=\"" + name + "\" method=\"post\"><ul>";
    return structure;
}//formStart

public String printPageHeader(String name) {
    String structure = "<li class=\"listLi\">\n<h3 class=\"formHeader\">" + name + ".</h3></li>";
    return structure;
}//printPageHeader

public String startMyLi() {
    String structure = "<li class=\"listLi\">";
    return structure;
}//startMyLi

public String endLi() {
    return ("</li>");
}//endMyLi

public String displayWithSpan(String str) {
    String structure = "<span class=\"labelSpan\">" + str + "</span>";
    return structure;
}//displayWithSpan

public String displayInputElement(String name) {
    return("Hiiiii");
}//displayInputElement

%>
However, I get an exception while calling the member.jsp file. This is the exception I get :
org.apache.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: xx in the jsp file: /member.jsp
The method formStart(String) is undefined for the type add_005fmember_jsp
Same is the case with all other methods. Where am I making the mistake ?

Thanks

Using 
<%@ include file="/html_functions.jsp" %>
works fine instead of <jsp:include page="html_functions.jsp" />

There are two ways of including a file in to the JSP page of your application. These are as follows: 

<%@include file="relativeURL" %>
<jsp:include page="relativeURL" />
first case includes the file or the text or the code of the file in the calling JSP file at compilation time and executes later.

See

and check html_functions.jsp is placed in correct path.
