What are the wallet path credentials for Web3j?

+2 votes

I want to develop smart contracts from my host with java + web3j to a private ethereum network which runs on my virtual machine. I am using the readme guide https://github.com/web3j/web3j. Look at the following lines:

Web3j web3 = Web3j.build(new HttpService());  // defaults to http://localhost:8545/
Credentials credentials = WalletUtils.loadCredentials("password", "/path/to/walletfile");

 How should I create this wallet? Should I generate an account on my VM and then copy wallet.json file to my host?

Follow the below steps:

  • Go to the private key file (For geth: AppData/Ethereum/keystore and for ethAppData/Web3/keys)
  • Find the key. It'll something like this: 
  • Use this as the second parameter in the WalletUtils.loadCredentials 
To create the wallet using web3j:
String fileName = WalletUtils.generateNewWalletFile(
        "your password",
        new File("/path/to/destination"));
