Variable substitution in template tags

[Ro...@shell.ca]

Hello Everyone,  

I am a brand new user; only subscribed about 15 minutes ago.

My team is doing some preliminary investigations into the use of struts
for rendering jsp-based browser pages.  I took a close look at the
struts-template sample application, and we are okay with setting our
template header and sections using put and get statements.  However, we
have added an extra dimension to it in which we actually pick up
different template headers depending on our user's locale, and then we
define specific template file names in resource bundle properties files.

Based on our structure, we need to do a VARIABLE (or properties key)
SUBSTITUTION, as follows:

<template:insert template='<bean:message key="templateName.JSP"/>' />

Or variable substitution as follows:
<template:insert template='<%= somePreviouslyDefinedVariableName %>' />

We do the same for puts and gets, etc, thereby nesting bean tags in
template tags.  We have of course include the struts-bean.tld file in
our taglib declarations, as well as defined our Resource Application
parameter in web.xml. Tomcat squeaks when we perform this variable
substitution or nested tags.

Is this allowed?  Can anyone please give us directions, recommendations
as to how to go about substitution in struts tags generally?   

Thanks a lot!

Re: REQUEST for Multi-part form EXAMPLE

There is a simple multi-part form example in the WAR
example on my site.  It has validation in it though,
but that would be easy to remove.  The example is
using request scope and hidden fields to hold the
information from the last form.

Does anyone have an example of a multi-part form they would like to 
donate to the struts example library ?

Hey Rose, glad to see you joined the list!  There was just a posting
yesterday that addressed a similar problem where a person wanted to add a
Resource message as the value the "alt" attribute of the html:img but could
nest the <bean:message/> tag.

The answer I gave is below, try it out and see if it works:

==============================================
How about this:

<!-- MyResources would be replaced with whatever class name you used in the
application init-param you setup for the ActionServlet
-->
<jsp:useBean id="resouces" class="MyResources" />

<html:img src="someImage.png" alt='<%=
resources.getString("someImage.alt.text")
%>'/>
