<p>You should get the list of inputs, this is a snippet code using BitcoinJ to get input and outputs addresses:                    </p>

<pre><code>List&lt;TransactionInput&gt; inputs = tx.getInputs();

for (TransactionOutput out : outputs) {

<p>I am trying to obtain the addresses of entry of a transaction when I receive money, but I have not found the way. I have tried to create an address with the bytes obtained by calling <code>TransactionInput.getScriptSig().getPubKey()</code>, but I've only obtained a ScriptException. If I call <code>TransactionInput.getFromAddress()</code> (deprecated) the code is frozen. I don't want to have to make a call to the API of block explorer, it is too cumbersome. Is there any way of doing this? As it parses the transaction <a href="https://www.blochain.info" rel="nofollow">blockhain.info</a> to get that kind of information?</p>

I am trying to obtain the addresses of entry of a transaction when I receive money, but I have not found the way. I have tried to create an address with the bytes obtained by calling `TransactionInput.getScriptSig().getPubKey()`, but I've only obtained a ScriptException.

As it parses the transaction [blockhain.info](https://www.blochain.info) to get that kind of information?
