How to modify h2 port in Corda for IntelliJ?

0 votes

I want to change the h2 port from the default value to a custom value. The code is as follows:

build.gradle file :

node {

    name "O=A,P=B,Q=C"

    advertisedServices = []

    p2pPort 10108

    rpcPort 10109

    webPort 10110

    h2Port 50002

    cordapps = [

            "com.template:states-and-contracts:$version",

            "com.template:other-sources:$version",

            "net.corda:corda-finance:$corda_release_version"

    ]

    rpcUsers = [[ user: "edureka_user", "password": "12345678", "permissions": ["ALL"]]]

}

Main File:

startNode(providedName = CordaX500Name("O", "P", "Q"), rpcUsers = listOf(user),customOverrides = mapOf("h2Port" to 50002))

node.conf file:

 h2port=50002

myLegalName="O=A,P=B,Q=C"

networkMapService {

    address="localhost:10102"

    legalName="O=A,P=B,Q=C"

}

p2pAddress="localhost:10108"

rpcAddress="localhost:10109"

rpcUsers=[

    {

        password=12345678

        permissions=[

            ALL

        ]

        user=edureka_user

    }

]

webAddress="localhost:10110"

It is working fine via Command prompt but not when I use IntelliJ. Please help

When you use IntelliJ, the nodes are configured using the node driver and the build.gradle file is neglected.

To configure the h2 port of a node you need to specify it so that the node driver can be aware of the modification. You can use the following code (change it as per your requirement):

fun main(args: Array<String>) {

    driver {

        startNode(

            customOverrides = mapOf("h2port" to "12345")

        ).getOrThrow()

    }

}
