Axis2 > C

Apache Axis2/C provides facilities to the user to configure its Web Service clients to communicate with services via a proxy. This can be achieved in two different ways.

1. Configuring proxy programmatically for a particular client using service client API.

2. Enabling proxy globally for all the clients by configuring axis2.xml

This article by Supun Kamburugamuva touches Axis2/C and IIS ISAPI technologies and goes on to explain how these two technologies can be combined to create a rich communication platform.

Axis2/C supports MTOM (SOAP Message Transmission Optimization Mechanism) and SwA (SOAP with attachments) that allows you to easily implement clients and services to handle attachments either way. In addition, you can convert binary content to base64 and vice-versa while sending and receiving attachments. This tutorial discusses the API and configuration options for handling SOAP Attachments within Axis2/C.

In this introductory tutorial, Dimuthu Gamage explains how to use Axis2/Java tools to ease the development of Axis2/C Web Services.

Axis2/C is becoming the most featured and stable and enterprise grade Web Services engine for C. Written in C, memory handling in Axis2/C is very crucial. This article written by Manjula Peiris discusses a few important tips related to memory management in Axis2/C. The article is recommended reading for Web service implementors, module writers and consumers of Web services in Axis2/C.

Apache Axis2/C engine uses a client repository to load its libraries, modules and services. Generally user has to specify this repository using AXIS2C_HOME environment variable. Rather than having all (libraries, modules and services) in one directory, user can specify them using axis2.xml. Dinesh Premalal, explains..

Authentication is the mechanism for identifying one's self. in the context of the Internet, authentication serves as the primary means for filtering access to protected resources. HTTP, the Hypertext Transfer Protocol, is an accepted standard for exchanging hypermedia in a distributed and collaborative environment. HTTP 1.1, [1] is the latest version of the protocol, in popular consumption.

Authentication on HTTP 1.1 is a framework supporting two popular mechanisms for requesting and providing credentials in non-secure environments [2]. One, being the simple passing of username and password as encoded text, known as Basic Access Authentication and the other based on cryptographic hashes, known as Digest Access Authentication.

This article by Senaka L. Fernando serves as a guide to using  Extensions for HTTP Authentication in Axis2/C.

In this article by Dinesh Premalal, he introduces Axis2/C Service Client API for the beginner.
