Formatting strings in Struts2/Freemarker
I am very used to using JSP taglibs and el functions for formatting
text. In my current application I am using Struts2 with Freemarker as
the templating engine. I need to format a phone number that is pulled
from the database as 8888888888 to be (888)888-8888. Using el
functions you can just call a static method from some class. This
would be nice since I already have that static method and it is used
elsewhere in the app.
I would use JSP for this, but our template is already built in
Freemarker. There are also come JSP pages that use this phone
formatter as well. Actually I have already created the el function tag
and have been using it all over in the app.
I have tried several things including trying to use el functions in
freemarker or even including JSP pages from freemarker.
Any ideas how this is done in the Struts2/Freemarker world? I am open
to any idea.

This worked! Thank you, Wes!!
<@s.property value="@package.class@formatPhone('${Session.USER.customer.phone}')"/>

Have you tried to use a struts2 tag with OGNL? If I am understanding
correctly, you could use -
@s.property value="@package.class@staticMethod('OGNL.pathTo.variable')
Of course, I don't know freemarker, and this is assuming you can reach
the variable from OGNL.

That approach works except in your following note it should be
<tiles:importAttribute name="myList" />
<c:forEach var="item" items="${myList}">
c:out value="${item}" />
</c:forEach>
Thanks a lot.

I think that you could use the list attribute:
<definition....>
<putList name="myList">
<add value="myfirst.css" />
<add value="mysecond.css" />
</putList>
</definition>
And in your JSP:
<tiles:importAttribute name="myList" />
<c:forEach var="item" items="myList">
<c:out var="item" />
</c:forEach>

RE: Tiles-def.xml
Posted by "Zhang, Larry (L.)" <lz...@ford.com>.
My problem is:
I have 10 (or more ) css files, some pages use 2 of those, some of those
uses 5 of those, some pages use 6 of those, and this combination is
totally random. Then we I create tiles template, I can't put all these
css in the template, instead I thought I can do the following:
My template:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en-us">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"
/>
<title><tiles:getAsString name="title" ignore="true"/></title>
<style type="text/css" media="screen">
<tiles:getAsString name="myCss1" ignore="true"/>
<tiles:getAsString name="myCss2" ignore="true"/>
<tiles:getAsString name="myCss3" ignore="true"/>
<tiles:getAsString name="myCss4" ignore="true"/>
<tiles:getAsString name="myCss5" ignore="true"/>
<tiles:getAsString name="myCss6" ignore="true"/>
<tiles:getAsString name="myCss7" ignore="true"/>
<tiles:getAsString name="myCss8" ignore="true"/>
<tiles:getAsString name="myCss9" ignore="true"/>
<tiles:getAsString name="myCss10" ignore="true"/>
</style>
</head>
<body>
<tiles:insert attribute="header"/><br />
<tiles:insert attribute="bodyContent"/><br />
<tiles:insert attribute="footer"/><br />
</body>
</html>
Then I need to define myCss1 and etc in the tiles-def.xml, I don't know
what is the good one to define this, I don't want to define
them like the following :
<definition name="default" path="/jsp/common/main.jsp">
<put name="header" value="/jsp/common/header.jsp" />
<put name="footer" value="/jsp/common/footer.jsp" />
</definition>
<definition name="mySepeficPage" extends="default">
<put name="title" value="SMERF > Change Request Queue" />
put name="myCss1" value="the path to the Css1"
<put name="bodyContent" value="/jsp/mySpefic.jsp" />
</definition>
Since that will make my tiles-def.xml too massy.
So the original issue is how to put the dynamic css files in the
template between <head>....<head>. I would think this is a common issue
for tiles community. Do you have any better way to resolve this issue?

No, but probably you can do it in another way.
What do you want to do exactly?

*lol* Huge step off a short pier--I'm good at those.
Hmm, yeah, I didn't know about the lack of JSP tag
file support, but that's a good one to keep a handle
on, so thanks for the extra pursuit :)
On my list to add to the wiki.

Thank you for that. That was a huge step in the right direction.
However, that does not work.
freemarker.core.InvalidReferenceException: on line 4, column 146 in
template/xhtml/components/loginlink.ftl unitag.phone not found.
I found a snipped over on Freemarker's forum that says Freemarker does
not support some JSP 2.0 features. Bummer. That means this will
probably work if I just write a taglib instead. Or I have to wait
until they realease 2.3.11. Currently they are on 2.3.10...

Re: Formatting strings in Struts2/Freemarker
Posted by Scott Kingdon <sc...@kingdon.net>.
If that works that would be great. I tried it, but maybe I am doing
something wrong.
In the JSP world, in order to use an el function you need to declair
it at the top of the page like this:
<%@ taglib prefix="uni" uri="UniFunctions" %>
When I put this at the top of a Freemarker page, it just gets printed
out to the page as text. So that does not work.
I tried declaring it in the JSP page before the freemarker template is
called. Then I called the el function like this in my template.ftl:
${uni:phone(session.USER.customer.phone)}
This spews out a nasty error. Freemarker complains that it does not
know what to do with uni:phone.

Re: Formatting strings in Struts2/Freemarker
Posted by Dave Newton <ne...@yahoo.com>.
Since you can use any S2 tag inside a FreeMarker
template I guess I had assumed you could use the same
syntax to call static methods you can from JSP, does
that not work?
(AFAIK you can also expose the JSTL library to a
FreeMarker page but I'm not sure how the two ELs would
play together; w/ OGNL you can use the %{...} EL
escape.)
