hi Using AXIS handlers some ways could be
1) Throw an exception in the handler( Not an elegent way ). 2) Implement some logic in web service1 so that it does not process but sends response saying Authentication failed. Alternatively using BPEL the same can be achieved elegently Based on response of webservice 2 the flow can call web service 1 or return to client.

But how will the handler terminate the flow if the authentication fails and pass authentication succes message for the execution of webservice.
