Attachment Demo

This demo brings up three nodes, and sends a transaction containing an attachment from one to the other.

To run from the command line in Unix:

  1. Run ./gradlew samples:attachment-demo:deployNodes to create a set of configs and installs under samples/attachment-demo/build/nodes
  2. Run ./samples/attachment-demo/build/nodes/runnodes to open up three new terminal tabs/windows with the three nodes and webserver for BankB
  3. Run ./gradlew samples:attachment-demo:runRecipient, which will block waiting for a trade to start
  4. Run ./gradlew samples:attachment-demo:runSender in another terminal window to send the attachment. Now look at the other windows to see the output of the demo

To run from the command line in Windows:

  1. Run gradlew samples:attachment-demo:deployNodes to create a set of configs and installs under samples\attachment-demo\build\nodes
  2. Run samples\attachment-demo\build\nodes\runnodes to open up three new terminal tabs/windows with the three nodes and webserver for BankB
  3. Run gradlew samples:attachment-demo:runRecipient, which will block waiting for a trade to start
  4. Run gradlew samples:attachment-demo:runSender in another terminal window to send the attachment. Now look at the other windows to see the output of the demo
