JSP无法在Tomcat中正确呈现 [英] JSP not rendering properly in Tomcat
问题描述
我在Tomcat中运行的JSP页面无法正确呈现。以下是helloworld.jsp的样子：
I have a JSP page running in Tomcat that is not rendering properly. Here is what helloworld.jsp looks like:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="cms-taglib" prefix="cms" %>
<html>
<head>
<title>${content.title}</title>
</head>
<body>
<cms:mainBar
dialog="my-page-properties-dialog"
label="Page Properties"
adminButtonVisible="true"/>
<h1>${content.title}</h1>
<p>Hello Magnolia World !</p>
Current time: <%= new java.util.Date() %>
<%-- JSP Comment --%>
</body>
</html>
，最终输出如下：
<％@ page
contentType =text / html; charset = UTF-8
language =java％><％@ taglib
uri =cms-taglibprefix =cms％> Hello
Magnolia World！
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@ taglib uri="cms-taglib" prefix="cms" %> Hello Magnolia World!
Hello Magnolia World！当前时间：
<％= new java.util.Date（）％><％ - JSP
评论 - ％>
Hello Magnolia World ! Current time: <%= new java.util.Date() %> <%-- JSP Comment --%>
简而言之，看起来只有表达式$ {content.title}被评估并呈现得很好，但其他所有内容如页面指令，其他JSP表达式和JSP注释都没有。
In short, it seems like only the expression ${content.title} is evaluated and rendered fine but everything else like the page directives, other JSP expressions and JSP comments are not.
我正在使用Tomcat附带的CMS，但分发的JSP模板样本似乎很好。我想我上面写的代码有点不对。
I'm using a CMS that comes with Tomcat but the JSP templates samples from the distribution seem fine. I suppose it's something wrong from the code I written above.
更新：我修复了日期表达式和注释的关闭标记。但是，页面指令未被解析。
Update: I've fixed the closed tag for the date expression and the comment. However, the page directives aren't being parsed.
推荐答案
我发现了问题。这是我的一个愚蠢的错误。即使我修复了正确的JSP语法并使用了jsp扩展，我还是要告诉CMS引擎将这个模板显式地呈现为JSP。感谢大家抓住我的语法错误。我想在使用其他框架时要注意这一点。
I found the problem. It's a stupid mistake on my end. Even though I fixed the correct JSP syntax and had the jsp extension, I needed to tell the CMS engine to explicitly render that one template as JSP. Thanks everyone for catching my syntax error though. I suppose it's something to watch out for when working with other frameworks.
