I am developing a Struts
based application. I am new to Struts. I want to use html
tags , specified in a taglib directory provided by Struts
, in a JSP
page.
But don't know how to use it. I know how to use taglib directive but I came to know from sources that the .tld file has been embedded in a .jar file after version 1.2.8. I am using Struts version 2.1.8.
I don't know in which .jar file the struts-html.tld
file is located.
I'm using Struts 1.3.10 for this illustration:
/WEB-INF/lib
folder./WEB-INF/tld/
folder (it must be situated in the /WEB-INF/ folder).On web.xml add the following stuff (under the <web-app>
element)
<jsp-config>
<taglib>
<taglib-uri>/WEB-INF/struts-bean.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/struts-bean.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/WEB-INF/struts-html.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/struts-html.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/WEB-INF/struts-logic.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/struts-logic.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/WEB-INF/struts-nested.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/struts-nested.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/WEB-INF/struts-tiles.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/struts-tiles.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/WEB-INF/sslext.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/sslext.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/WEB-INF/struts-layout.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/struts-layout.tld</taglib-location>

</jsp-config>
This tells that once you call your TLD from the JSP, your webapp will look for the matching <taglib-uri>
then look for it's location on <taglib-location>
and find relevant class to call.
On your JSP, now you can do this:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-layout.tld" prefix="layout"%>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt" %>
<%@ taglib uri="http://java.sun.com/jstl/fn" prefix="fn" %>
Hope this helps.
