JSP Comment end symbol not recognized in some cases
Summary: JSP Comment end symbol not recognized in some cases
Product: Tomcat 4
Version: 4.1.9
Platform: PC
OS/Version: Windows NT/2K
Status: NEW
Severity: Normal
Priority: Other
Component: Jasper
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: maxhearn@aol.com
The JSP compiler does not recognize ---%> (note the three dashes) as
ending a JSP comment that was started with the <%-- sequence.
Examples:
The following are treated as valid JSP comments:
<%-- Hello --%>
<%-- Hello x--%>
The following is treated as an unterminated comment:
<%-- Hello ---%>
A JSP comment is defined informally in the JSP 1.2 spec as:
<%-- anything bug a closing --%> ... --%>
It is defined formally in the JSP 2.0 spec as:
'<%--' JSPCommentBody
JSPCommentBody ::= ( Char* - ( Char* '--%>' ) ) '--%>'
Test case to reproduce the problem:
HelloWorld.jsp:
<%-- Comment ---%>
<html>
<head>
<title>Hi</title>
</head>
<body>
Hey there
</body>
</html>
