Handler and Phase in Apache Axis2

by Deepal Jayasinghe | June 2008 | Java Open Source

The fundamental goal of any given Simple Object Access Protocol (SOAP) processing framework is to deliver an incoming SOAP message to the target application. However, if we consider today's Web Services or any other application, just delivering the message to the application is not sufficient. We need to provide quality of service, such as reliability and security.
