[Opensource] Question on MessageBundles and Struts validation

[Wise, Malcolm]

Eddie,

For message bundles, you can also use the <c:fmt> JSTL tags, e.g.

<fmt:setBundle basename="com.cal.cp.MessageBundle"/>
...
...
<fmt:message key="message.key"/>

or, if you're using multiple bundles in a single page, you can wrap the
<fmt:message> tag like so:

<fmt:bundle basename="com.cal.cp.MessageBundle">
  <fmt:message key="message.key"/>
</fmt:bundle>

Using JSTL means that you don't need to specify message bundles in the
struts-config.xml.  Also, you can specify a default message bundle for JSTL
(e.g. Struts ApplicationResources) in web.xml (assumes ApplicationResources
is in WEB-INF\classes):

<context-param>
  <param-name>javax.servlet.jsp.jstl.fmt.localizationContext</param-name>
  <param-value>ApplicationResources</param-value>
</context-param>

Doing this means you don't need the <fmt:setBundle> tag.

HTH,
Malc

Eddie,

I believe you want to use the Struts tags on that one.

Good question!  :)  Expresso has no problem working with Struts form beans, 
so I've seen no reason why Validator can't work with Expresso as well.  I 
haven't tried it, but AFAICT there's no obstructions to making it 
work.  The only difference would be error handling, but I believe that 
could be picked up in the controller's state.

I just haven't been able to get to giving it a spin myself.

                                                         -Mike
