What path should I give for credentials in web3j

Question

I am using the readme guide https://github.com/web3j/web3j. What I am interested is developing smart contracts from my host with java + web3j to private ethereum network which runs on my virtual machine. 

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

Answer 1

WalletUtils.loadCredentials can be buggy, I would recommend creating the accounts before hand, and then you can extract the private key and use Credentials.create(privateKey) You can use the keystore file and use myetherwallet to view your private key.
