I want to make activiti which can be used for many clients (each with different database). I want to make a central database with database information of all other database (like database name, user and password). First i need to get information from central database of all databases, list all the database name and then user select the required database with activiti. and , according to selection i need to connect required databse with information set in central database. How can this be possible? If any idea or any tutorial for this would greatly appreciated.
