Handler questions

[Jinyuan Zhou]

Hi there,
Is there a quick way to apply handler/chain  to my webservices without
involving writing a module. I understand that  axis2 has a flexible
architecture about modules, flows, dispatchers. But I am looking for kind of
two-step process. 1. Writ a handler 2. modify services.xml.  May be I am
missing some thing?
Thanks,
Jack
