Why Tomcat is Persistent Object?

Hi Guys,

Recently I am facing a crazy problem, I am running a servlet that recommends items based on a data model. The data model has to be loaded into an object from a database each time user makes a request to the server and since the data is the same for all the users I would like this object to be loaded once only. I am very new to Tomcat and don’t know where to look so any advice will be appreciated.

Thanks & Regards
