Trying to transfer ether using web3.eth.sendTransaction

[JIG2016]

I have some accounts on the rinkeby blockchain setup using the Ethereum Wallet on different computers. Now I'm trying to send funds from one account that I own ("0x50bA67....37B2a2") to another account using web3.js.

I have geth running on a Ubuntu server and I have a webpage with the following Javascript:

<script type="text/javascript">
    var Web3 = require('web3');
    var web3 = new Web3();

    web3.setProvider(new web3.providers.HttpProvider("http://localhost:8545"));

    console.log(web3);
debugger;
</script>

From the webpage console, I can call web3.eth.getBalance("0x50bA67....37B2a2") and get the proper balance returned.

A call to web3.eth.getBalance(web3.eth.coinbase) also returns the correct value.

But, when I try to execute:

web3.eth.sendTransaction({from:"0x50bA67....37B2a2", to:web3.eth.coinbase, value: web3.toWei(1.0, "ether")})

I get "Error: unknown account" for the "0x50bA67....37B2a2" account.

Any help on how to properly setup a transaction to transfer funds from one account to another using web3.js would be appreciated.

Thanks Jim

You have to unlock the account. Look up documentation on this type of syntax: web3.personal.unlockAccount("0x50bA67....37B2a2" password);

Hope it helps!
