I don't remember what was the reason for this implementation. Need to 
have a look at it again.

sure, also see

http://wyona.com/pipermail/yanel-development/2009-April/003455.html
http://bugzilla.wyona.com/cgi-bin/bugzilla/show_bug.cgi?id=6982

As as start I think we should make it at least configurable within 
conf/yanel.xml, whereas we might
rather want to make it configurable within WEB-INF/web.xml because it 
its web app think and not really
anything to do with Yanel itself.

WDYT?

Thanks
