Given the information as follows:Brainstorming

Later, I found the cause of the error:

<jsp:include page="${pageContext.request.contextPath}/hyperLinkList.jsp "> </ jsp: include> error, because this sentence is a result of an EL expression used here,${pageContext.request.contextPath}The EL expression results in an error, because the <jsp: include page = "${pageContext.request.contextPath}/hyperLinkList.jsp "> </ jsp: include> This sentence is written in home.jsp page,

And we knowjsp eventually translated into a Servlet, we can go and seehome.jsp pageTranslationAfterServlet. In tomcat directory \ work \ Catalina \ localhost \ Your Project Name \ apache \ under \ org jsp directory, you can findhome.jsp pageTranslationAfter thisServlet, name home_jsp.java.

turn onhome_jsp.java this file, you can see the code below, home.jsp page <jsp: include page = "${pageContext.request.contextPath}/hyperLinkList.jsp "> </ jsp: include> phrase wasTranslationRearWillto makeThe following line of code,Figure:Use thePageContextImpl.proprietaryEvaluate(

org.apache.jasper.runtime.JspRuntimeLibrary.include(request, response, (java.lang.String) org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate("${pageContext.request.contextPath}/hyperLinkList.jsp", java.lang.String.class, (javax.servlet.jsp.PageContext)_jspx_page_context, null, false), out, false);

So I guess, this should be$ {PageContext.request.contextPath} due to an error,I guess it is in the home.jsp translationAfter Servlet to time, as long as there have been expressions of EL place, the final completion of the analysis will give expression to the emergence of EL

2 side edges are double quotation marks (&quot;), Which led to File&quot;/xml/hyperLinkList.jsp&quot; not foundFile path not found problem.${pageContext.request.contextPath}This sentence is to get the project name, you can also understand the root directory into the project, some people called virtual path.

My project name is called xml, so$ {PageContext.request.contextPath} this sentence was/ Xml, so${pageContext.request.contextPath}/hyperLinkList.jsp sentencefinallyTranslationRearIt is/xml/hyperLinkList.jsp

As I guess above,

In the home.jspTranslationAfter Servlet to time, as long as there have been expressions of EL place, the final completion of the analysis will give expression to the emergence of EL

2 side edges are double quotation marks (&quot;), So eventuallyTranslationBecame the&quot;/xml/hyperLinkList.jsp&quot;This path, andAnd we projectShe did not call&quot;/xml/hyperLinkList.jsp&quot;The name of the page!This is the reason being given,This is my guess! Is not necessarily so, but also experts advise! Thank you!

Next we need to do is remove${pageContext.request.contextPath}The EL expression, OK, we changed

<jsp:include page="/hyperLinkList.jsp"></jsp:include>

TranslationAfter below: Obviously, ah,Remove${pageContext.request.contextPath}After the EL expression,TranslationAfter the use of different classes,

It is used belowJspRuntimeLibrary.include(

Then we open home.jsp page in a browser will not be given up!

note:
EL expressions include instructions not supported - <% @ include file = "$ {pageContext.request.contextPath} /hyperLinkList.jsp"%>This
Kind of writing is not supported,You will get an error HTTP Status 500 - /testInclude.jsp (line: 50, column: 2)

File "${pageContext.request.contextPath}/hyperLinkList.jsp" not found

EL include operation expressions using the error-prone -
<jsp:include page="${pageContext.request.contextPath}/hyperLinkList.jsp"></jsp:include> This
Kinds of writingYou will get an error HTTP Status 500 - javax.servlet.ServletException:
File &quot;/xml/hyperLinkList.jsp&quot; not found

include action (jsp: include) to support the wording of EL expressions, but
Yesimage<jsp:include page="${pageContext.request.contextPath}/SaveData2"></jsp:include>This write Servlet path wordingAfter parsing will be more
A path out of the project name, java.io.FileNotFoundException:
The requested resource (/ xml / xml / SaveData2) is not available File Not Found ultimately lead

include action (jsp: include) the page property support jsp, html, and writing path Servlet
The include directive (@include) the file attribute only supports jsp, html page that does not support Servlet path, the wording does not support EL expressions
include (included) use EL expressions, we must pay more attention and careful
