I'm developing a small bitcoin service and I've got everything working great except for one hangup: I can't for the life of me figure out how to programatically extract the private key from the wallet.
I looked at bitcoinj but it appears to use a different format than the standard client.
I'm pretty new to bitcoin so maybe I'm missing something obvious.
The only way I've been able to do this so far has been modifying bitcointools to show the whole address in a dump and parse it out by hand.
Is there code floating around to do this in java with the standard berkley db format?

Ok, it just came through at roughly an hour and a half.
Is that about what I can expect?

Here's the dump:

Before running with debug it said something about having broadcast through 9 nodes.

dood,
I'm clearly new at this so I can't answer your question.
From my reading the transaction fee is optional at least until some indeterminate time in the future?
If everything requires a transaction fee to be processed at all than I guess I've misunderstood what bitcoin was.
Are you saying that unless I pay a transaction fee its up in the air whether the transaction will be processed?

Thanks to some friendly people on this site I got a few bitcents to play with and tried a few transactions this weekend.
While the first couple I made seemed to get confirmed in about a half hour I'm waiting on one right now for over an hour.
I've seen 5 or 6 blocks get generated since the transaction was submitted but still nothing.
Is this normal? Are there transactions that just never get confirmed?

Is there another service out there like bitcoin faucet for a complete noob?
It figures that the very day I start to read about bitcoin it gets shut down.
I checked in the suggested #bitcoin-faucet irc but it doesn't look like its an active group.
All the other options for getting even a small amount of bitcoin seems like it would take about a week.

Of course if anyone can spare a few cents while its down so I can try it out it would be much appreciated!
