If JSTL (along with EL) had not happened then I agree that developing the
<bean:message> tag would be a good idea - simplest solution would have been
a <bean:arg> tag so that you could do something like the following...
<html:message key="msg.hello">
<bean:arg>
<bean:write name="user" property="userName"/>
</bean:arg>
</html:message>
However much of the functionality in the bean and logic tags is now provided
by JSTL - including messages with the above type of functionality...
<fmt:message key="msg.hello">
<fmt:param>
<bean:write name="user" property="userName"/>
</fmt:param>
</fmt:message>
As you also point out you can also use "EL" to achieve what you want with
the <bean:message> tag without having to resort to scriptlets.In my mind
theres a difference not developing further tags whose functionality have
been replaced by JSTL (mostly bean and logic) and the those which haven't
(html, tiles, nested). These two examples both come in that category.

After some reasoning, I must say that I must disagree with James statement.
A very simple example. I need to greet the user in his language.
I will help a message like this in my messages_en.properties:
msg.hello=Hello {0}
And in messages_de.properties
msg.hello=Hallo {0}
Now I have my page, the right locale and the user object. Without EL, how
can I ever right the proper greeting?
The only way today would be:
<bean:define id="username" type="java.lang.String" name="user"
property="userName" toScope="page"/>
<bean:message key="msg.hello" arg0="<%=username%>"/>
Imho the taglib can't be considered complete, as long as there are <%= %> in
the jsp.
It would be so simple to provider the message tag with argXName/argXProperty
similar to name/property attributes it already has and parallel to arg0-arg5
it already has.
<bean:message key="msg.hello" arg0Name="user" arg0Property="userName"/>
Would it hurt someone? I don't think so.
And there are a lot of examples where really simple functionality is missing
in struts tags.
For example compare tags don't allow second bean/property as value.
Other thing. How many struts-tags actually do log? Maybe 20%? Shouldn't it
be unified?
If there are people, who are ready to implement this, why wouldn't you let
them? :-)
