As per instructions on https://docs.corda.net/docs/corda-os/4.4/tutorial-cordapp.html#running-nodes-across-machines

However, i never come across in documentation how to access the CORDA Crash shell in ubuntu to type in Corda interactive shell to execute the following ! Creating an IOU via the interactive shell # We can create a new IOU using the ExampleFlow$Initiator flow. For example, from the interactive shell of PartyA, you can agree an IOU of 50 with PartyB by running flow start ExampleFlow$Initiator iouValue: 50, otherParty: "O=PartyB,L=New York,C=US".

Can anybody clarify how to launch access to Corda interactive shell when on remote ubuntu machine?

Newbie problems running example cordapp

Asked 2020-Mar-31 at 07:03

I'm new to Corda, so am following the "Getting started developing CorDapps".
On my MacBook Pro, I have: - installed the JDK, IntelliJ Community edition and Git, - have downloaded the sample project (using git clone) by following Step One) - created an IntelliJ project (by following Step Two) but, when following instructions for Deploy the CorDapp locally (using ./gradlew clean deployNodes), I get the following errors:

Task :contracts-java:compileJava FAILED

/Users/samples/cordapp-example/contracts-java/src/main/java/com/example/state/IOUState.java:5: error: package com.google.common.collect does not exist import com.google.common.collect.ImmutableList; ^ ... and another 3 similar.

I've searched google, gradle and IntelliJ forums, but cannot find anyhting that helps resolve my issue.

Can someone point me in the right direction please? Thanks a lot!

ANSWER

Answered 2020-Mar-30 at 21:55

As recommended here, Open IOUState.java and:

Remove this import: import com.google.common.collect.ImmutableList;
Modify ImmutableList.of(new IOUSchemaV1()) to Arrays.asList(new IOUSchemaV1())

How to setup H2 for Corda

Asked 2020-Mar-02 at 10:34

I am re-writing and running a IssueFlow for an example cordapp here. I can see the flow is successful and can find a number of UTXOs on the vault query for the node.

...

ANSWER

Answered 2020-Mar-02 at 10:34

I was unable to find tables in H2 instance as my connection string was wrong & H2 appears is creating a blank db when trying to connect to a non-existant DB.

In DBeaver , you can add the JDBC url, but it automatically pre-fixes 'jdbc:h2:'

ANSWER

That error is just a warning output by the driver tests when byteman (a java agent) is not used. You can ignore it.

runPartyXServer is likely just starting the spring web app, not running the node itself.

Try running the nodes/runnodes.sh script or java -jar corda.jar in the directory of each generated node.
