Hi J-Miguel, I'm doing excatly that for quite some time now: Using bitcoinj in the backend of a spring boot webapplication (still in development). The a bit frustrating thing I noticed is that bitcoinj is not really built to handle the bitcoin payment logic for potentially many users. It's my impression that it's really made for phone wallets or small scale bitcoin applications. In my post here https://groups.google.com/forum/#!topic/bitcoinj/FFI0qtIl4PU you see that it's not really possible to sync bitcoinj once you have a big number of keys in your wallet (e.g. ~200k). Maybe that's possible once you run your own full node and connect bitcoinj to it - I'm not sure. But also bitcoinj can't "forget" old issued keys that you'll not expect to receive payments to. So every address you ever issued and showed to a user will be tracked for ever and cause a listener callback for every new block. So the amount of work your application has to handle every 10 minutes will grow over time.
And yes I use the WalletAppKit class it bundles a lot of things like saving the wallet to disk, connecting it to the peerGroup etc. I still operate outside of the wallet logic, you have access to the internal objects such as transactions, issued receive addresses via walletKit.wallet() Best regards, Tobias Am Dienstag, 10.
