SCWCD : JSP Document (XML-based document) that uses the correct syntax
Write a JSP Document (XML-based document) that uses the correct syntax.
JSP syntax comment:
<%-- comment --%>
has no XML syntax analog.
JSP syntax page directive:
<%@ page ... %>
XML syntax page directive:
<jsp:directive.page ... />
JSP syntax taglib directive:
<%@ taglib ... %>
has no XML syntax analog.
jsp:root element is annotated with namespace information:
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:eg="http://java.apache.org/tomcat/examples-taglib"
xmlns:test="urn:jsptld:/tomcat/taglib"
xmlns:temp="urn:jsptld:/WEB-INF/tlds/my.tld"
version="2.0">
...
</jsp:root>
A taglib directive of the form
<%@ taglib uri="uriValue" prefix="prefix" %>
is translated into an xmlns:prefix attribute on the root of
the JSP document, with a value that depends on uriValue.
If uriValue is a RELATIVE path, then the value used is
urn:jsptld:uriValue.
If uriValue is a ABSOLUTE path, then
uriValue is used directly.
<%@ taglib tagdir="tagDirValue" prefix="prefix" %>
is translated into an xmlns:prefix attribute on the root of the
JSP document, with a value of the form urn:jsptagdir:tagDirValue.
JSP syntax include directive:
<%@ include file="relativeURL" %>
XML syntax include directive:
<jsp:directive.include file="relativeURL" />
A file on the local system to be included when the JSP page is translated into a servlet.
The URL must be a relative one.
JSP syntax declaration:
<%! ... %>
XML syntax declaration:
<jsp:declaration> ... </jsp:declaration>
Declarations are translated into a jsp:declaration element.
For example:
<%!
public String someFunc(int i) {
if (i<3) return("...");
}
%>
is translated into the following:
<jsp:declaration>
<![CDATA[
public String someFunc(int i) {
if (i<3) return("...");
}
]]>
</jsp:declaration>
Alternatively, we could use an < and instead say:
<jsp:declaration>
public String someFunc(int i) {
if (i<3) return("...");
}
</jsp:declaration>
JSP syntax scriptlet:
<% ... %>
XML syntax scriptlet:
<jsp:scriptlet> ... </jsp:scriptlet>
JSP syntax expression:
<%= ... %>
XML syntax expression:
<jsp:expression> ... </jsp:expression>
JSP syntax template text:
some template text
XML syntax template text:
<jsp:text>
some template text
</jsp:text>
A JSP document syntax:
<html>
<title>positiveTagLib</title>
<body>
<%@ taglib uri="http://java.apache.org/tomcat/examples-taglib"
prefix="eg" %>
<%@ taglib uri="/tomcat/taglib" prefix="test" %>
<%@ taglib uri="WEB-INF/tlds/my.tld" prefix="temp" %>
<eg:test toBrowser="true" att1="Working">
Positive Test taglib directive </eg:test>
</body>
</html>
A XML document syntax:
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
xmlns:eg="http://java.apache.org/tomcat/examples-taglib"
xmlns:test="urn:jsptld:/tomcat/taglib"
xmlns:temp="urn:jsptld:/WEB-INF/tlds/my.tld"
version="2.0">
<jsp:text><![CDATA[
<html>
<title>positiveTagLib</title>
<body>
]]></jsp:text>
<eg:test toBrowser="true" att1="Working">
<jsp:text>Positive test taglib directive</jsp:text>
</eg:test>
<jsp:text><![CDATA[
</body>
</html>
]]></jsp:text>
</jsp:root>
