Bitcoin-JSON-RPC-Client

Bitcoin-JSON-RPC-Client is a lightweight Java bitcoin JSON-RPC client binding. It does not require any external dependencies.

Code example

    private static final Bitcoin bitcoin = new BitcoinJSONRPCClient();

    public static void sendCoins() throws BitcoinException {
        bitcoin.sendToAddress("1EzGDMdqKW5ubTDNHSqCKciPkybGSvWgrj", 10);
    }

    public static void receiveCoins() throws BitcoinException {
        final BitcoinAcceptor acceptor = new BitcoinAcceptor(bitcoin);

        System.out.println("Send bitcoins to " + bitcoin.getNewAddress("NewAccount"));

        acceptor.addListener(new ConfirmedPaymentListener() {
            HashSet processed = new HashSet();

            @Override
            public void confirmed(Transaction transaction) {
                if (!processed.add(transaction.txId()))
                    return; // already processed

                System.out.println("Payment received, amount: " + transaction.amount() + "; account: " + transaction.account());
                try {
                    if (bitcoin.getBalance("NewAccount") >= 10)
                        acceptor.stopAccepting();
                } catch (BitcoinException ex) {
                    ex.printStackTrace();
                }
            }

        });
        acceptor.run();
    }
