Welcome to Apache Axis2/C

Axis2/C is an effort to implement Axis2 architecture, in C. Axis2/C can be used to provide and consume Web Services.

Background and Motivation

Axis 2 Java team released 1.0 recently. This implementation provides another language option to consume and provide Web Services. Performance being its forte, Axis2/C is looking at broadening its horizon by providing extensions to popular open source scripting languages and web browsers.
