Subject: Caching for Database objects
Does anyone know how can we introduce caching for database objects.
We are getting the data from database tables which is then converted to Java
objects.
We want to build some kind of caching mechanism so that we don't have to go
to database whenever a request for data (Java objects) comes in.
Any suggestions will be appreciated.
Thanks
Manmeet
