bean:message with dynamic key?
I want to write a bean:message with a dynamic key such as:
<bean:message key="<c:out value='$foo' />bar" />
So that my ApplicationResources.properties can display:
foobar = A combined key resulting in text.
Can anyone help with this?

For the record, it's "${foo}bar" not "${foo + 'bar'}"; unfortunately,
the JSTL EL doesn't support string concatenation (it'll try to convert
the value of foo and the string 'bar' to integer values, which will of
course fail).

Start here: http://struts.apache.org/faqs/struts-el.html
The Struts-EL taglib goes hand in hand with JSTL 1.0, and gives you the
ability to use expressions in Struts tag attributes, the same way you can
use them in JSTL tags.
I'm not quite sure what the answer to your original question is-- without
trying it, I'd guess either key="${foo}bar" or maybe key="${foo + 'bar'}".
When you find the right syntax, it should work in either <fmt:message> or
<bean:write> (the EL version) if you decide to go with that.

Can you please explain this a bit more?:
If you're using <c:out>, (JSTL 1.0 on a Servlet 2.3 container,) you should
be using the Struts-EL tags instead of the original ones. Then you can use
an ${expression} for the 'key' attribute.

If you're using <c:out>, (JSTL 1.0 on a Servlet 2.3 container,) you should
be using the Struts-EL tags instead of the original ones. Then you can use
an ${expression} for the 'key' attribute.
Or, use JSTL's <fmt:message> tag. In that case, you'll need to add a
context param to web.xml so JSTL can see the .properties file:
<context-param>
<param-name>javax.servlet.jsp.jstl.fmt.localizationContext</param-name>
<param-value>ApplicationResources</param-value>
</context-param>
