Failed to use SolSample.java

[marlonprudente]

I trying to use SolSample with Ganache, my method is the same:

	private static void deploy() {
		Web3j web3j = Web3j.build(new HttpService(Environment.RPC_URL));
		Credentials credentials = Credentials.create("9797ab180fae3c9fa50c1b713beb5e08e012a303de04760349712dbcf6d497c1");//可以根据私钥生成
                System.out.println("Address: " + credentials.getAddress());
		RemoteCall<TokenERC20> deploy = TokenERC20.deploy(web3j, credentials,
				Convert.toWei("10", Convert.Unit.GWEI).toBigInteger(),
				BigInteger.valueOf(3000000),
				BigInteger.valueOf(5201314),
				"my token", "mt");
		try {
			TokenERC20 tokenERC20 = deploy.send();
			tokenERC20.isValid();
		} catch (Exception e) {
			e.printStackTrace();
		}

	}

but, the error is:
