Axis2/C

One of the main deployment scenarios of Apache Axis2/C is with Apache Web Server. Best performance and stability can be gained by deploying Axis2/C in Apache. When deployed in Apache server, Axis2/C uses the memory pools supplied by Apache and guarantees zero memory leaks. Also due to custom memory implementation Axis2/C can perform up to its maximum.

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

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

This article by Lahiru Gunathilake illustrates the latest performance results of Apache Axis2/C and compares with the performance of Axis2/C with Guththila XML parser and libxml2 XML parser.

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.

The Axis2/C Web services platform is a great platform for developing Web services. One of the modules that is a part of this platform is Apache Savan/C, a WS-Eventing implementation module. The purpose of this article is to discuss how this platform was used in one of my client projects, which required an eventing solution as a component. This article by Damitha Kumarage, he discusses this eventing solution in addition to providing valuable information for those planning on hosting their services with Apache Axis2/C.

In this tutorial, Part 1 of a series by Damitha Kumarage, he describes Web services Eventing with Apache Savan/C. Damitha illustrates working with Apache Savan/C, an implementation of the WS- Eventing specification. This tutorial complies with the WS-Eventing Specification of August 2004.
