Subject Re: Struts and I18N

Hi Neal,

have you checked out the Struts example application in VelocityTools? 
It includes a number of "mini-webapps" that demonstrate using various
Struts features with VelocityTools.  I believe the mini-webapp "app1"
demonstrates use of the MessageTool for internationalization.

also, i'm curious where/how your are generating these emails?  are you
doing this within the servlet? is it as part of a servlet request? 
where/how are you creating/getting a Context to merge with the

there's a lot that's unclear to me about the way you are approaching
this.  and to try and clear up your last curiousity there:  yeah, the
VelocityViewServlet is the main way in which the MessageTool is
initialized and added to the Context before processing the template. 
so, depending on where/how you are processing your email templates, it
may be easy to get a working MessageTool, or it may not.  it's hard to
say without knowing your setup better.

for sure.

 (Am I wrong?)  I have setup the web.xml and toolbox.xml just like the Velocity website says.
 I have updated part of the template with the following line:
> <head>
>   <title>$msg.get("app.title.txt") - Alert Details</title>
>   #include($styleSheet)
> </head>

through regular Struts forwards, etc.  From what I understand VelocityViewServlet is necessary
to use the MessageTool?  We are using VelocityEngine (via mergeTemplate) and I believe that
I'll need to replace this with usage of VelocityViewServlet?
