Is it possible to sync up my database with liferay database. To explain briefly, lets say if I have a DB with some tables to capture user details and their roles. This database is configured with separate application (may be a seperate portlet). This application is used to maintain user detail and their roles.Now my question is how can I sync up this user detail with liferay user detail such that whatever modifications I do with this DB, that should effect in my liferay database as well. For example, if I create a new user in my dabatabse , liferay database should also get updated with this new user.
Hope I am clear with my question. Any help will be appreciated.
And also need some suggestion for good tutorial for Portlet with spring MVC.
