Summary: No translation error messag when using #{...} in
template text
Product: Tomcat 6
Version: 6.0.20
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
AssignedTo: [email protected]
ReportedBy: [email protected]
JSP.2.2 requires a translation error when an #{...} EL expression is used in
templated text.
(See also the Section 1.2.4 of "JavaServer Pages 2.1 Expression
Language Specification".)
Tomcat 6.0.18 *erronously* parse the expression.
Tomcat 6.0.20 *rightly* does not but it also does not issue any error like the
JSP specs requires.
An example might clarify. Given the following JSP snip:
--- [snip] ---
<?xml version="1.0" encoding="UTF-8"?>
<jsp:root version="2.1"
xmlns:jsp="http://java.sun.com/JSP/Page";
xmlns:c="http://java.sun.com/jsp/jstl/core";
xmlns:f="http://java.sun.com/jsf/core";
xmlns:h="http://java.sun.com/jsf/html";>
<jsp:directive.page contentType="text/html;charset=UTF-8"
pageEncoding="UTF-8"/>
<jsp:output omit-xml-declaration="no"
doctype-root-element="html"
doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/>
<f:view>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<link rel="stylesheet"
href="#{facesContext.externalContext.requestContextPath}/resources/theme/current/css/screen.css"
type="text/css" />
<link rel="shortcut icon"
href="#{facesContext.externalContext.requestContextPath}/resources/theme/current/img/favicon.ico"
type="image/x-icon"/>
</head>
<body>
<!-- ... -->
</body>
</html>
</f:view>
</jsp:root>
--- [/snip] ---
With Tomcat 6.0.18 I get:
--- [snip] ---
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<!-- ... -->
<link rel="stylesheet"
href="/my-web-app/resources/theme/current/css/screen.css"
type="text/css" />
<link rel="shortcut icon"
href="/my-web-app/resources/theme/current/img/favicon.ico"
type="image/x-icon"/>
</head>
<!-- ... -->
</html>.
--- [/snip] ---
Instead with Tomcat 6.0.20:
--- [snip] ---
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<!-- ... -->
<link rel="stylesheet"
href="#{facesContext.externalContext.requestContextPath}/resources/theme/current/css/screen.css"
type="text/css" />
<link rel="shortcut icon"
href="#{facesContext.externalContext.requestContextPath}/resources/theme/current/img/favicon.ico"
type="image/x-icon"/>
</head>
<!-- ... -->
</html>.
--- [/snip] ---
But neither an error nor a warning message appear in the log.
