Subject RE: How to create a general resource bundle for JSTL?
Date Tue, 08 Jul 2003 14:28:47 GMT
Hi Martin

Thanks for the answer. However, your solution relies on JSTL alone, and this
works for me without any problems (see my code).
What doesn't work is setting a resource bundle with my Java class, without
having to set the bundle in the JSP.

Best regards,
Eric

Hey Eric,

Let me give you an educated yet untested guess. I'm not very experienced
with JSTL, but noticed you weren't getting any response so let me try. 

Have you tried setting the Locale of the ServletResponse object? I'm not
100% certain, but it seems to me JSTL *SHOULD* check this when using their
I18N tags. Furthermore if you want to use a resource bundle for a bunch of
tags it might do you some good to put the other I18N tags below them as
nested tags:

<fmt:setBundle basename="vulgarInsults"/>

<!-- Notice how the bundle tag surrounds the others... -->
<fmt:bundle basename="org.apache.bookies">
  <fmt:message key="threat" >
    <fmt:param value="${address}"/>
    <fmt:param value="${numberOfChildren}"/>
    <fmt:param value="${nameOfSpouse}"/>
  </fmt:message>
</fmt:bundle>

Greetings,
