我通过Maven构建了春天的新例子spring-petclinic（https://github.com/SpringSource/spring-petclinic/）。

我将welcome.jsp更改为：

<!DOCTYPE html> 

<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>


<html lang="en">

<jsp:include page="fragments/headTag.jsp"/>

<body>
<div class="container">
<jsp:include page="fragments/bodyHeader.jsp"/>
<h2><fmt:message key="welcome"/></h2>
<spring:url value="/resources/images/pets.png" htmlEscape="true" var="petsImage"/>
<img src="${petsImage}"/>
       <!--                      <FCK:editor instanceName="${status.expression}"  
                            toolbarSet="Default" width="800" height="600"  >  
                            <jsp:attribute name="value">This is some <strong>sample text</strong>   
                            </jsp:attribute>   
                        </FCK:editor> 
     <iframe src="sampleslist.jsp"   scrolling="no" width="100%" height="100px"></iframe>
    <iframe name="Sample" src="jsp/sample01.jsp" width="100%" height="400px">   </iframe>
-->
<jsp:include page="fragments/footer.jsp"/>

</div>
</body>

我刚刚在welcome.jsp上添加了一些评论，然后服务器给出500错误：任何机构都知道为什么？以及如何纠正500错误？

如果要进行JSP注释，正确的语法是：

<%-- this is comment, which will be ignored by JSP compiler --%>

您在标准HTML评论<jsp:attribute>中使用了错误的<!-- -->标记。
