I’m trying to implement an IM system using Smack and Openfire. It turns out that I will need to store more variables for each user account. For example, I may also need to store the IP and public key in addition to the regular username and password. Is that possible to change the Smack api and Openfire (and its embedded database) as well to allow for that? For this specific example, do you have any hints at what I’ll probably need to look at and change?
