How to create raw transaction I've started creating my own wallet in bitcoinj and I have serious problem. I want to create raw transaction without wallet object. So I wrote this piece of code:

    //String to a private key
    DumpedPrivateKey dumpedPrivateKey = DumpedPrivateKey.fromBase58(params, 
            privKey);
    ECKey key = dumpedPrivateKey.getKey();

    //String to an address
    Address address2 = Address.fromBase58(params, address);

    Transaction tx = new Transaction(params);
    //value is a sum of all inputs, fee is 4013
    tx.addOutput(Coin.valueOf(amount-4013), address2);

    //utxos is an array of inputs from my wallet
    for(UTXO utxo : utxos)
    {
        TransactionOutPoint outPoint = new TransactionOutPoint(params, utxo.getIndex(), utxo.getHash());
        tx.addSignedInput(outPoint, utxo.getScript(), key);
    }

    tx.getConfidence().setSource(TransactionConfidence.Source.SELF);
    tx.setPurpose(Transaction.Purpose.USER_PAYMENT);

    System.out.println(tx.getHashAsString());
    b_peerGroup.GetPeerGroup().broadcastTransaction(tx);


But this ends with:


  mandatory-script-verify-flag-failed (Script evaluated without error but finished with a false/empty top stack e


What is wrong with my code?

EDIT:
I found a solution. I've changed only this line: tx.addSignedInput(outPoint, utxo.getScript(), key, Transaction.SigHash.ALL, true);
Sure :)

My solution was pretty simple:

//String to a private key
DumpedPrivateKey dumpedPrivateKey = DumpedPrivateKey.fromBase58(params, 
        privKey);
ECKey key = dumpedPrivateKey.getKey();

//String to an address
Address address2 = Address.fromBase58(params, address);

Transaction tx = new Transaction(params);
//value is a sum of all inputs, fee is 4013
tx.addOutput(Coin.valueOf(amount-4013), address2);

//utxos is an array of inputs from my wallet
for(UTXO utxo : utxos)
{
    TransactionOutPoint outPoint = new TransactionOutPoint(params, utxo.getIndex(), utxo.getHash());
    //YOU HAVE TO CHANGE THIS
    tx.addSignedInput(outPoint, utxo.getScript(), key, Transaction.SigHash.ALL, true);
}

tx.getConfidence().setSource(TransactionConfidence.Source.SELF);
tx.setPurpose(Transaction.Purpose.USER_PAYMENT);

System.out.println(tx.getHashAsString());
b_peerGroup.GetPeerGroup().broadcastTransaction(tx);
