Words that speak to ur Heart

Well after all these are not Technical to Software but defenetely to ur life.

A careless word may kindle strife;
a cruel word may wreck a life;
a timely word may level stress;
a loving word may heal and bless.
The happiest of people don't necessarily have the best of everything they just make the most
of everything that comes along their way

Welcome to Sandesha

The software industry is moving more towards service oriented implementations. Web services play a major role in the above movement and there are several new concerns have been identified as crucial when integrating this model in to the business applications. As with most client server applications reliable way of message transfer is a must for business applications that are implemented using web services.

One such concern is the reliability of the message flow between the client and the service. IBM, Microsoft, BEA and Tibco came up with a specification named WS-RelibaleMessaging Protocol providing a model of message for a reliable message delivery system.

Sandesha is an open source project that provides an implementation for the above specification. Sandesha is implemented on top of Apache Axis(Apache eXtensible Interaction System) that provides an extensive support for web services. The set of features provided by Sandesha can be described as follows.

* An implementation for WS-ReliableMessaging with the support to WS-Policy and WS- Addressing.
* Interoperability with other WS-ReliableMessaging implementations.
* A monitor component that can be used to create artificial message delivery failure and out of order delivery scenarios that can be used to test the Endpoint Mangers.

Sandesha provides a complete support for WS-ReliableMessaging specification allowing a reliable communication between web services as well as web service and clients. It also provides the INORDER message delivery assurance for the users."
