testnet 上的智能合约如何部署上去？

[qq364390162]

payloadType = Transaction.PayloadType.DEPLOY;
payload = new TransactionDeployPayload("js", "var demo = 1;", "").toBytes();
// deploy from == to
tx = new Transaction(chainID, from, from, value, nonce, payloadType, payload, gasPrice, gasLimit);
manager.signTransaction(tx,passphrase);

使用java版本sdk里面的测试demo部署智能合约，一直是pending状态，不能成功是为什么
