This document provides an overview of the Apache Axis2 web services framework. It discusses the pre-Axis2 era, the motivation for Axis2's architecture, and its key features. These include a high-performance XML processing model, extensible messaging engine, pluggable modules, and easy deployment. Axis2 uses AXIOM for its XML object model and supports features like WS-Addressing, reliable messaging, and security. The document also outlines how Axis2 projects fit together and provides resources for using Axis2 in applications and learning more.
