Welcome to the Sandesha2 for Java Architecture Page

Sandesha2 is a module that runs within the Axis2 framework. For more information on Axis2 modules, please see here

Architecture Overview

Sandesha is a reliable messaging engine based around the semantics and wire-protocol from the WSRM specification. It uses the services of Axis2 to send and receive messages. This architecture guide is partitioned into three parts:

• Core runtime
• WSRM implementation details
• Axis2 integration

Sandesha Runtime design

• Configuration and Policy
• Threading
• Transactions
• Storage
• Serialization
• Client API
• Failure Cases

WSRM implementation model

The following sections use terminology defined in the WSRM 1.0 and 1.1 specifications. We also offer a very brief WSRM primer.

• RM Source Sequence Lifecycle
• RM Destination Sequence Lifecycle
• Retransmission and Acknowledgment model
• CreateSequence model
• Replay
• MakeConnection

Axis2 Integration

• Handlers
• MessageReceiver
• Module
