What is new in Axis2 deployment?


As mentioned in Chapter 1, Apache Web Services and Axis2, one of the main goals of the Axis2 design is to provide more user friendliness; in the meantime, providing better extendibility and flexibility to the system. When it comes to user friendliness, service deployment is one area where the user needs less work. As a result, Axis2 supports a very convenient deployment model with a number of new features, compared to Apache Axis1. Some of the commonly used and useful sets of features are shown here:

  • J2EE-like deployment mechanism (archive-based)

  • Hot deployment and hot update

  • Idea of repository

  • Change in the way of deploying handlers (modules)

  • Deployment descriptors

  • Deployment options

The following figure shows the J2EE-like deployment mechanism:

In any J2EE application server, you can deploy an application as a self-contained package, where you can bundle all your resources, configuration files, and binary files together into one file, and deploy it.

Isn't that easy...
