Letter of Credit Demo

This is a CorDapp that uses a letter-of-credit business scenario to showcase Corda.

This CorDapp was written with the goal of creating a good demo, not a commercial letter-of-credit application. A real letter-of-credit application would be tweaked, especially in terms of the contract code.

Running the nodes:

Create the node driver by running ./gradlew buildExecutableJar (osX) or gradlew buildExecutableJar (Windows)
Run the node driver using java -jar kotlin-source/build/libs/eloc-demo.jar

If you receive error messages that say Exception in thread "main" java.net.BindException: Address already in use, you have zombie Java processes. You can kill them using killall java -9 on osX, or wmic process where "name like '%java%'" delete on Windows.

Interacting with the nodes:

Once all the nodes are started, go to http://localhost:10014/web/loc/. Follow the script here: https://github.com/corda/LetterOfCredit/blob/release/script.md.

Update process (development only)

Updating the web frontend

If the front-end has been modified, it needs to be redeployed onto the nodes. You do this by

Clone the front-end project
Run npm install in the root folder of the project
Building the front-end project by running ng build --prod --aot --build-optimizer --base-href="/web/loc/" from the root of the project
Navigate to the newly created 'dist' folder within the root of the front-end project
Copy the entire contents of the 'dist' folder into the CorDapp project at 'LetterOfCredit\kotlin-source\src\main\resources\loc'
Redeploy CorDapp as above
