  1. No ethereumj is a Java client implementation of the Ethereum yellow paper. It is a client.

Generate Ethereum addresses using a library such as keythereum.

  1. You mean Ethereum? You can create a feature to allow them to..

  2. They can sign transactions using the private key that you generate for them which you have allowed them to download (see question 2).
