Trader demo

This demo brings up five nodes: Bank A, Bank B, Bank Of Corda, NonLogging Bank and a notary node that they all use. Bank A will be the buyer, and requests some cash from the Bank of Corda in order to acquire commercial paper from Bank B, the seller.

The NonLogging Bank node is present to demonstrate the usage of the "Configuring Responder Flows" feature of Corda described here. The override is defined within the deployNodes section of the build.gradle. In this case, we are overriding the default responder for net.corda.traderdemo.flow.SellerFlow to be a version that does not print out information about the transaction.

    node {
        name "O=NonLogging Bank,L=London,C=GB"
        p2pPort 10025
        rpcUsers = ext.rpcUsers
        rpcSettings {
            address "localhost:10026"
            adminAddress "localhost:10027"
        }
        extraConfig = ['h2Settings.address' : 'localhost:10035']
        flowOverride("net.corda.traderdemo.flow.SellerFlow", "net.corda.traderdemo.flow.BuyerFlow")
    }

To run from the command line in Unix:

Run ./gradlew samples:trader-demo:deployNodes to create a set of configs and installs under samples/trader-demo/build/nodes
Run ./samples/trader-demo/build/nodes/runnodes to open up five new terminals with the five nodes
Run ./gradlew samples:trader-demo:runBank to instruct the bank node to issue cash and commercial paper to the buyer and seller nodes respectively
Run ./gradlew samples:trader-demo:runSeller to trigger the transaction. If you entered flow watch, you can see flows running on both sides of transaction. Additionally you should see final trade information displayed to your terminal

To run from the command line in Windows:

Run gradlew samples:trader-demo:deployNodes to create a set of configs and installs under samples\trader-demo\build\nodes
Run samples\trader-demo\build\nodes\runnodes to open up five new terminals with the five nodes
Run gradlew samples:trader-demo:runBank to instruct the buyer node to request issuance of some cash from the Bank of Corda node
Run gradlew samples:trader-demo:runSeller to trigger the transaction. If you entered flow watch, you can see flows running on both sides of transaction. Additionally you should see final trade information displayed to your terminal
