PermittedTaglibsTLV |
A TagLibraryValidator class to allow a TLD to restrict what
taglibs (in addition to itself) may be imported on a page where it's
used.

ScriptFreeTLV |
A TagLibraryValidator for enforcing restrictions against
the use of JSP scripting elements.

TLVs allow translation-time validation of the XML view of a JSP page. The TLVs provided by JSTL allow tag library authors to enforce restrictions regarding the use of scripting elements and permitted tag libraries in JSP pages.
For example, any JSP page that imports the tag library with the following Tag Library Descriptor (TLD) file will be restricted to using JSTL tags:
<?xml version="1.0" encoding="UTF-8" ?> <taglib xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd" version="2.1"> <description> Restricts JSP pages to the JSTL tag libraries </description> <display-name>permittedTaglibs</display-name> <tlib-version>1.1</tlib-version> <short-name>permittedTaglibs</short-name> <uri>http://java.sun.com/jstl/permittedTaglibs</uri> <validator> <validator-class> javax.servlet.jsp.jstl.tlv.PermittedTaglibsTLV </validator-class> <init-param> <description> Whitespace-separated list of taglib URIs to permit. </description> <param-name>permittedTaglibs</param-name> <param-value> http://java.sun.com/jsp/jstl/core http://java.sun.com/jsp/jstl/fmt http://java.sun.com/jsp/jstl/sql http://java.sun.com/jsp/jstl/xml </param-value> </init-param> </validator> </taglib>
