how to create menues with tiles2?

[xbranko]

Following the example at the tutorial page I am not getting the menu rendered. There is no exception, and instead of the menu, I get the iterator control variable displayed.

tiles-def.xml:
  <definition name="menu" template="/Menu.jsp">
    <put-list-attribute name="menu.Attributes">
      <item value="Home page" link="menu.do" />
      <item value="News" link="news.do" />
    </put-list-attribute>
  </definition>

  <definition name="main" template="/main.jsp">
          <put-attribute name="mymenu"    value="menu" />
  </definition>

Menu.jsp:
<%@taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles" %>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<div align="center">
  <tiles:importAttribute name="menu.Attributes"/>
    <c:forEach var="item" items="${menu.Attributes}">
      <a href="${item.link}">${item.value}</a> |
    </c:forEach>
</div>

What gets rendered on the page:
${item.value} |

Why is this? What am I doing wrong or not setting up correctly?
This is with tiles 2.0.6

Many thanks,
Branko

I think that you have EL evaluation turned off, you have to specify at
least Servlet 2.4 version in your web.xml file.

According to my web.xml it should be on 2.5:
<web-app id="WebApp_ID"
         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_5.xsd"
         version="2.5">

Is there some other way to turn EL evaluation explicitly?

You also probably need to define an id name and type when importing

How does one do that? And where? In my tiles-def.xml, menu definition has a name "menu", that is being used as a value in the other definition.

No in the import tag in the jsp page. Sorry not at my computer right now so I can't send example. The import tag requires Id, name and class. Hth - rick

Rick is correct, there is a problem with dots in "menu.Attributes",
because, without the "toName" attribute, it will be imported in the
"menu.Attributes" name under page scope.
So, either use a "toName" attribute, e.g.:
<tiles:importAttribute name="menu.Attributes" toName="menuAttributes"/>
<c:forEach var="item" items="${menuAttributes}">
...

Or change its use in <c:forEach>, e.g.:
<c:forEach var="item" items="${pageScope['menu.Attributes']}">

Oh, BTW, this root element is wrong, since from 2.5 Sun renamed "j2ee"
to "javaee", do a search-and-replace from one to the other.

I did everything that was suggested. Changed the web.xml (j2ee -> javaee), used the 'toName' on import, used the pageScope[''] notation, but am still getting the same behavior, i.e. no menus! I've even changed the name by removing the dot menu.Attributes -> menuAttributes.

What else can it be? What else should I try? In the debugger can see menuAttributes are being passed as attribute of the pageContext, but they are not being used. The ForEachTag is setting the items over which to iterate over to literal ${pageScope['menuAttributes']}, and not to what this evaluates to! Where is this supposed to be evaluated?

Mmm one last chance, try to use this:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core_rt" %>

This gives:
org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jsp/jstl/core_rt cannot be resolved in either web.xml or the jar files deployed with this application

Eclipse Web tools jsp editor also flagged this as a problem. Does this work for you? Do you have a small self contained test example that you could share? I can try it on my end and try to see what is different. Any other idea? Anyway -- just wanted to say a big THANK YOU for all your help!

Oh right, sorry, you are under Servlet 2.5, that do not need the "_rt"
versions of JSTL.
I was using this one since I use Servlet 2.4.
At this point I don't know what to say, but to try with another
application server :-(
