Re: using JSP2.0 / JSTL1.1 with Struts

Hi Erez,

Yes, downloaded Standard 1.1 and use that in my app - it says on this page:

http://jakarta.apache.org/taglibs/doc/standard-doc/intro.html

"Standard-1.1 (JSTL 1.1) requires a JSP container that supports the Java Servlet 2.4 and JavaServer Pages 2.0 specifications. Jakarta Tomcat 5 <http://jakarta.apache.org/tomcat/> supports the new specifications. The Standard-1.1 taglib has been tested with Tomcat 5.0.3."

Jason,

Thanks for replying me though it took me sometime to try it out.
What about JSTL 1.1? Do I have to download it by myself and replace the Previous 1.0 version? Or is it part of JBoss or Tomcat 5.0?

Thanks again,

Erez

Hi all,

Until now I've been using Struts 1.1 with JSP1.2/JSTL 1.0 with the use
of JSTL EL extension for Struts tags.
Html-el etc..
Now I'd like to move on and take advantage of the JSP2.0 and JST1.1 new
features.
I am running with JBoss 3.2.5 + Tomcat 5.0.

Any special steps? Do I need to download JSTL 1.1 by myself ?

Thanks in advance,

Erez




Don't know about the JBoss side of things. But I'm using Tomcat 5.0+JSP2.0/JSTL1.1

I guess this question is going to come again too... :)

I think the main points are:

1. change the web.xml declaration to have

<web-app xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
version="2.4">

So that it uses Servlet 2.4 + JSP2.0

2. Tag-libs: no longer need to be specified in the web.xml, so you can remove those entries
You don't use the struts-el tags, as EL is provided by the container.
In the JSP you include the taglibs for example:

/WEB-INF/jsp/include/prelude.jspf:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core";
%><%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt";
%><%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions";
%><%@ taglib prefix="html"
uri="http://jakarta.apache.org/struts/tags-html";
%><%@ taglib prefix="logic" uri="http://jakarta.apache.org/struts/tags-logic";
%><%@ taglib prefix="bean"
uri="http://jakarta.apache.org/struts/tags-bean";
%><%@ taglib prefix="tiles" uri="http://jakarta.apache.org/struts/tags-tiles";
%><%@ taglib prefix="nested" uri="http://jakarta.apache.org/struts/tags-nested";
%><%@ taglib prefix="display" uri="http://displaytag.sf.net";
%>

I think that is all that is required, there is an optional step 3:
3. Read the JSP2.0 spec for the newweb.xml <jsp-config> option for controlling JSPs
Which allows things like those tag-libs above to be included on every JSP page
eg

   <jsp-config>
   <jsp-property-group>
       <description>JSP Configuration</description>
       <display-name>JSPConfiguration</display-name>
       <url-pattern>*.jsp</url-pattern>
       <!-- no scriplets, only taglibs can be used -->
       <scripting-invalid>true</scripting-invalid>
       <page-encoding>UTF-8</page-encoding>

<include-prelude>/WEB-INF/jsp/include/prelude.jspf</include-prelude>
       <include-coda>/WEB-INF/jsp/include/coda.jspf</include-coda>
   </jsp-property-group>
   </jsp-config>


Let me know if I missed anything...
