yes,
you can use jstl to locate your form. then you can access it's properties via el and use the jstl tags for display.
Here is the jsp code to accomplish this
---- code start ---- <[EMAIL PROTECTED] prefix="c" uri="/WEB-INF/tld/c.tld" %>
<c:set var="formName" value="${requestScope['org.apache.struts.action.mapping.instance'].name}"/>
<c:set var="formScope" value="${requestScope['org.apache.struts.action.mapping.instance'].scope}" />
<c:if test="${formScope=='request'}"> <c:set var="form" value="${requestScope[formName]}" scope="request" /> </c:if> <c:if test="${formScope=='session'}"> <c:set var="form" value="${sessionScope[formName]}" scope="request" /> </c:if> --- code end ---
I usually place this code in a jsp and include it my page when i need to expose the FormBean easily to the page.
ex. <jsp:include page="/jsp/common/form.jsp" />
Then i use the following syntax in my page:
<c:out value="${form.myValue}"/>
This would allow you to use all the jstl stuff to format values stored in your FormBean.

That's what I use when just outputting the contents of a bean; but I'm trying to format the data in form fields.
If I can't combine <html:text> and <bean:write> (or JSTL's <fmt:format>) tags, is there another way to achieve this?
Thanks,

The Struts <bean:write> tag offers a format attribute (or

want to use a resource file). But JSTL would be a better option if you can use it in your environment.

Thought I'd throw this out in the middle of the week again...
Kind of a conceptual question: how do you format Dates, Numbers, Currencies, etc. for *form fields* inside the JSP?
I know I could do in in the ActionForm getters, but: 1. I don't know the locate of the user at that point 2. I'd have to recompile the ActionForm every time I want
to make a
change to the *view* - seems like a bad practice.
What I'm looking to achieve is something similar to
<fmt:format> JSTL tag,
where you can specify a format mask, or even a format "style" defined elsewhere.
Thanks,

I would like to state a basic assumption I deduced in learning
struts, then
pose a question.
Assumption: ActionForm property getters and setters should
return and take
Strings.
My initial impulse was to try passing the actual data types
(Dates, Numbers,
etc.); however, the Struts mechanism seems to pass Strings to
the ActionForm
setter methods on form submission (which throws a conversion
Exception of
course). Then I tried making the setters take Strings, and
getters return
the actual data types, but this seemed to confuse the introspection mechanism; plus I didn't see any way to apply formatting inside the html:text tags (like you can in JSTL's fmt:format tags).
Question: How does one handle formatting data (custom
formatting or i18n)
for (pre/re)population of a form?
Ex.: An update form; a user's information is loaded from the
database into
classes (Strings, Dates, Numbers, etc.). If you want to format
this data,
you have to do it in the Model, as the ActionForm only takes and gives Strings - which seems to be a Bad Practice. Even if you had
additional
special setters for the explicit purpose of populating the
ActionForm from
original data types, you still don't know what Locale the
client is from.
Is my assumption incorrect? Is there a basic flaw in my
understanding of
the use of ActionForm? Or there an actual short-coming, and
workaround?
In short, How Can You Format Data For Strut's Form Tags Inside
The Actual
JSP :-) ?
Thank you for any input.
