Topic: Is there a way to see why a transaction isn't getting relayed? (Read 1599 times)
An unencrypted wallet sents the testnet coins fine. It is an encrypted wallet issue, hope this information helps.
It seems that the key is getting set to null in the Privkey variable and the encrypted variable, I am going to try with a new unencrypted wallet and see what I can do, and see if it was the encryption. Here is a debug screenshot.
Here is the output of wallet.toString()
And here is the parts where I set u bitcoinj.
Code:
Wallet containing 6.30 BTC in:
1 unspent transactions
0 spent transactions
0 pending transactions
0 dead transactions

You could look at WalletAppKit to simplify the setup code.
I can't see the issue off-hand and I'm heading out for the night in a few minutes. It's apparently a bug or at the very least, poor documentation on how to use the encryption feature. If you put a breakpoint on Transaction.signInputs() line 837:
then take a look at the key object and see why both hasPrivKey() and isEncrypted() are false. I'd expect hasPrivKey to be false and isEncrypted to be true.
If you can't see what's going wrong, send me all your code and I'll try and make time tomorrow or Monday night to debug it.

BTW you don't need commitTx - broadcastTransaction will call it for you once the transaction propagates (which in this case it isn't, but that's a separate issue).
The issue is that the signature is being substituted with a dummy signature because the private key isn't usable. We can see this here:
That big run of zeros means it's using Transaction.dummySignature(), which is meant to be replaced by something else later. So the question is, why does it think it doesn't have the private key. I guess the issue is how the wallet is being encrypted. Therefore the next step is - please paste the output of wallet.toString() and ideally, the rest of your program.

Can you post your code please? I've not seen a case of invalid signatures before, but of course if you use the API wrong you could create such things accidentally.
I looked in my debug.log and posted it tech support board to get clear statement of why bitcoind will not relay bitcoinj transactions on the testnet. Maybe possible bug.

I am directly connected to my bitcoind on the testnet but none of my transactions are getting relayed. Even when I send to an address the bitcoind controls it doesn't show it being unconfirmed or any balance. How can I debug these transactions?
