Subject RE: using <fmt:message> with Tiles and Struts

Ah. Yes, that's the problem... The tag is the "rt" version (run time) which
does not accept expressions. 

JSTL comes with 2 sets of tags. One el (expression-language) and the other
rt (runtime), which allows scriplets to be entered into tags.

Download them here:

I'm assuming you mean the jar? It's just the usual jstl.jar and the tld is
fmt.tld

hnm.. I just looked at the tld and I've got class names like :

<tag>
    <description>
        Maps key to localized message and performs parametric replacement
    </description>
    <name>message</name>
    <tag-class>org.apache.taglibs.standard.tag.rt.fmt.MessageTag</tag-class>


I'm assuming now that I somehow am using the wrong tld.. if I am, can you
direct me to the correct one?

Did you accidentally include the run-time version of fmt?

That was close to the first way I went about it. I did the following:

<tiles:useAttribute name="titleKey" scope="page"/>

and then I was able to access the key just fine ( I did a test of <c:out
value="${titleKey}" /> and got "home.title"), proving that the problem
wasn't in the way I was using the tiles attribute. 

For some reason, when I plugged in :

<fmt:message key="${titleKey}"/>

I got the usual ???${titleKey}??? message from the fmt:message tag

Perhaps I'm doing something wrong somewhere. I even tried just doing the
following as a test:

<c:set var="titleKey" value="home.title"/>
<fmt:message key="${titleKey}"/>
<fmt:message key="home.title"/>

and I got the following:

???${titleKey}???
Main Home Page

Vince,

You need to import the Tiles attribute before you reference it:

  <tiles:importAttribute name="titleKey" ignore="true" />
  <c:out value="${titleKey}" />

Thanks,
Paul

Subject: using <fmt:message> with Tiles and Struts


I am building a Struts Web application and I'm using Tiles for the first
time. I have it all set up and working nicely. My problem comes in the fact
that I want to use a standard messages.resources file for my page titles. 

For example

home.title=Main Home Page
info.title=Intro Page

etc.

I am used to setting the bundle at the top of the page like:

<fmt:setBundle basename="messages"/>

and then directly accessing keys as follows:

<fmt:message key="home.title"/>

however I am now using tiles so what I had hoped was to use a tiles
attribute to pass the key :

  <definition name=".home" extends=".baseDef">
   	<put name="titleKey"  value="title.home" />
  </definition>

and then use the key in the tile like:

<fmt:message key="${titleKey}"/>

however, nothing I've tried has worked (including just trying the
fmt:message tag w/o using Tiles like :
<c:set var="titleKey" value="home.title"/>) . 

For some reason, the fmt:message tag refuses to accept expression values. 

Can anyone offer me a best practice on how to handle this? Or at least solve
my problem?
