| But how about performance..
|
| is it better to have multiple instances of hibernate sessionFactory
| Objects
| (one each web app) or to use an http call for each db query?
|
| Maybe transactions are handled better with a centralized datasource access
| throug ws.. what do you think?

It sounds to me like you need to refactor your apps. Your portlets should use a business delegate to request your business logic functions. The business delegate should in turn call a session façade to perform the requested actions. This provides a clean separation between your application and business logic, and you can experiment with the linkage between the BD and SF to improve performance (maybe start with web services, as they're likely to be the least troublesome, then move to RMI if the performance isn't good enough).
