Can't start a IOUFlow from CordaShell (cordapp-template tutorial)

问题

I'm trying to run the IOU cordapp-template but when I start the IOUFlow from the shell I got this error

If the image isn't readable this is the command I'm providing

start IOUFlow arg0: 10, arg1: "CN=NodeB,O=NodeB,L=New York, C=US"

And this is the Error I got

[iouValue: Int, otherParty: Party]: missing parameter iouValue

However my object IOUFlow is correct, any suggestion on how to work on it?

回答1:

You don't supply the params as arg0, arg1 etc, but as the names of the parameters themselves.

i.e.

Mon Jul 31 10:45:54 BST 2017>>> flow start ExampleFlow iouValue: 10, otherParty: "CN=NodeB,O=NodeB,L=New York, C=US"

It's important to include the space between the : and the (e.g.) 10 value for parsing reasons.

回答2:

change it into

start ExampleFlow iouValue: 10, otherParty: "CN=NodeB,O=NodeB,L=New York, C=US"

even when you just run the the java example
