Subject Re: Can velocity load a properties file ?
Date Fri, 21 Apr 2006 01:07:03 GMT
Hi Barbara,
Hi Will,

Thanks a lot for your response.
As Will says, #set can make any class objects.
In fact, I often make instances of ArrayList, and use them.
But I think whether there are tools like org.apache.velocity.tools.
struts.MessageTool or not.

I will follow Will's advice to implement methods like $util.
getPropertyResourceBundle( path ) in $util.

BTW, why do you propse to limit to use reflection ?
It's a powerful way to provide such availability into velocity realm, I 
guess. Would you mind asking you for reasons ?

Best Regards,
trad-ex
