Hi @Swaraswi,

The Solace Java API does not have built-in file transfer functionality. Instead, you'll need to implement the file transfer yourself using publish/subscribe messaging.

1. On the sending side:
   • Read the file contents
   • Split the file into chunks if it's large
   • Publish each chunk as a message to a topic
2. On the receiving side:
   • Subscribe to the topic
   • Receive the file chunk messages
   • Reassemble the chunks
   • Write the reassembled file to the destination
3. You'll need to implement additional logic for things like:
   • Indicating start/end of file transfer
   • Handling errors and retries
   • Tracking progress
4. For large files, you may want to use Guaranteed Messaging to ensure all chunks are delivered reliably.

The exact implementation details will depend on your specific requirements. For the actual code to publish/subscribe messages using the Solace Java API, you should refer to the Solace Java API documentation and samples.

Here are some relevant resources for more information:

Keep in mind that this approach uses messaging to transfer file contents, rather than directly copying files between systems. The actual file I/O would be handled by your Java application code.
