How to start a flow in Corda

Nodes are not opening up properly after executing the runnodes script

QUESTION

How to start a flow in Corda

Asked 2020-Apr-19 at 12:34

I am exploring this cordapp example https://github.com/corda/corda-training-template.git

I have modified the code as per the solution template available in Github. Whenever I am starting the flow, I am getting error like (no constructor found, missing parameter state), please refer to the below screenshot. I have initiated this flow from node A so I am confused about what will be the constructor parameter. I have pasted the state code below.

I assume that one of the input parameters in your flow's constructor is a class (Amount), so you have to pass an instance of that class when you start the flow in the node's shell.
See here how to create an instance of a class in the node's shell.
The problem in your code is that you're using Amount; meaning to construct an instance, you'd have to do something like this:

QUESTION

Nodes are not opening up properly after executing the runnodes script

Asked 2020-Apr-17 at 08:15

I was exploring thIS cordapp example https://github.com/corda/corda-training-template.git

There is a total of 4 nodes (Notary, A, B, and C) in this example. I am trying to open all the nodes in a single run using runnodes script from the terminal.

But all the nodes are not opening at a time. It's like alternatively they are opening, onetime only Notary and C nodes are opening and another time A and B nodes are opening. Any specific reason? And also I am getting this message in the webserver terminal. Please explain. "The Corda specific webserver is deprecated and will be removed in future".

The runnodes script is not a very reliable way of starting up the nodes. Its mostly used for development purposes to make development faster.

It might sometimes not work as expected. The script works by opening up a terminal window and running the command to start the node in that particular terminal. Depending on the speed of the system, the command sometimes gets executed before the new terminal is opened up.

The reliable way to start a Corda node, however, is to use the java -jar corda.jar command. So just go into each individual nodes folder and run the command to start the node.

Here's the script :
