Reliable transfer of large messages

The Large message sender and receiver use the JMS semantics to transfer arbitrarily large messages over the network in chunks, using reliable JMS semantics. When large message transfer is initiated, all message fragments are sent through the server ensuring reliability. Files sizes in Gigabytes can be transferred.

No increase in cache/JVM heap size required

Although the message transfer happens through the server, the file fragments are sent to the receiver in a request-reply fashion. This enables the server to handle large message transfers without any increase in the cache/JVM heap size.

The Large message transfer is not restricted to any queue or topic

As mentioned above, large message transfer conforms to JMS semantics, allowing the user to transfer the message on any queue or topic.

Resume function at both sender and receiver end]

Broken transfers can be restored using the resume functionality built into the message class.
Message transfers are specific to the JMS Connection-Users involved in the transfer. The user can resume the transfers at any later point provided the participant at the other end is available.

Minimal changes in the application code

All the message transfer properties are built into the message object while the message transfer semantics are built into the normal JMS send and receive calls. Therefore, only minimal code changes are needed to send and receive large sized data.
