Overriding default action mapper
I've followed the instructions at
http://struts.apache.org/2.0.14/docs/actionmapper.html and defined my custom
mapper that extends DefaultActionMapper in struts.xml, but it won't load
because the mapper has already been loaded. I've never tried anything like
this before so I'm at a total loss to know what's wrong.
My struts.xml looks like this and the stack trace is below;
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<bean type="org.apache.struts2.dispatcher.mapper.ActionMapper"
name="struts"
class="com.vasilikon.dispatcher.mapper.ButtonWithParameterActionMapper" />
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true"/>
</struts>

Would this change to struts.xml be expected to work if I'm using the
convention plugin, or do I need to
configure the change in a different way?

this is how you do it:
