Subject Re: [Axis2] Can I declare a handler in service.xml?
Date Mon, 08 May 2006 04:09:40 GMT
Hi Laszlo;
It is by design we are not allow user to add handlers in services.xml,
in fact adding a handler is always done using a module. So as you said
you have to have a module with that handler.

You can configure handler using service , at the runtime when handler
ask for a parameter from the message context , it will first look in
AxisOperation , and then AxisService , next AxisServiceGroup etc...
So to solve your problem you can do smt like following;
  1. Create a module with that handler
  2. And set the phase of the handler as Dispatch (it will be good that
if you set that as phase last handler)
  3. Add those two parameters into services.xml ,
  4. When handler execute try to get those parameters and evaluate the
  5. So depending on the result you can change the AxisOperation.
