RE: SteemJ V0.3.4 has been released ~ Use the Steem API in your Java Project
This piece of code teaching how to create a new transaction is not working anymore:
[...]
Transaction transaction = new Transaction();
// The expiration date defines how long the transaction is valid. This field is optional and SteemJ will automatically use the current system time and an offset.
transaction.setExpirationDate("2016-04-06T08:29:27UTC");
// Define in which block the transaction should be added. In most cases this is the next available block which can be asked using the following lines:
GlobalProperties globalProperties = steemApiWrapper.getDynamicGlobalProperties();
int refBlockNum = (globalProperties.getHeadBlockNumber() & 0xFFFF);
transaction.setRefBlockNum(refBlockNum);
transaction.setRefBlockPrefix(globalProperties.getHeadBlockId());
// There is also the option to add extensions to a transaction which are currently not used by Steem and therefore not supported by SteemJ.
// transaction.setExtensions(extensions);
// A Transaction accepts one or more Operations which have to be provided as an ArrayList.
ArrayList<Operation> operations = new ArrayList<>();
[...]
Hay @discernente,
thank you for pointing this out and sorry for the late reply. I've updated the sample at GitHub. The following snippet should work again:
Ok, thank you. Now this piece of code is running fine, but I found another error while trying to run the method "getActiveVotes:

After having a closer look I guess the problem is that you've used the whole link instead of only providing the permlink part. So instead of
use:
ok thank you
Thank you once again - This may be connected to the new Steem version 0.19.2 - I've created #72 at GitHub for this :)
