Here's an example of what you have to put in a plugin in the
fuseactionException phase:
<cfcatch type="myApp">
<cfsilent>
<cfswitch expression="#cfcatch.type#">
<cfcase value="myApp.SecurityException">
do something
</cfcase>
<cfcase value="myApp.DatabaseException">
do something else
</cfcase>
<cfdefaultcase>
<cfrethrow>
</cfdefaultcase>
</cfswitch>
</cfsilent>
</cfcatch>
Hope it helps
