There are currently two products from the Apache Software Foundation for Web Services: there is version 2.3.1 of Apache SOAP and version 1.1 of a newer product called Axis.

The WWW pages for Axis are at http://ws.apache.org/axis/. The FAQ says that ‘Axis is essentially Apache SOAP 3.0. It is a from-scratch rewrite, designed around a streaming model (using SAX internally rather than DOM). The intention is to create a more modular, more flexible, and higher-performing SOAP implementation (relative to Apache SOAP 2.0).’
