What is the wallet path 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.

There are such lines:

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

So the question is:
How should I create this wallet? Should I generate account on my VM and then copy wallet.jsonfile to my host?

Answer 1

WalletUtils.loadCredentials is resplendent with bugs. Therefore, my recommendation would be to create accounts beforehand. After that, you can extract the private key and use the following line of code: 

Credentials.create(privateKey)

For viewing your private key, you can use the key store file and then use myetherwallet.
