Dimitri,
Welcome to JavaRanch
It's been a long time since i last used
Struts. As far as i know, the ActionServlet in the web.xml can be passed an init-param which will point to the struts configuration file. Something like:
<blockquote>
code:
<pre name="code" class="core">
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/conf/struts-care.xml</param-value>
</init-param></pre>
</blockquote>
I think, the param-value for this config supports comma separated values, which means that you can specify multiple files.
I'll move this to our Struts forum, where you might get more help.
P.S: Later on, if this turns out to be specific to the taglib being used, then the moderator is free to move this back to "Other Open Source Projects" forum.
