When user loge in I am making a call to database and retriving a collection of objects(Each object represents a table row). I don't want to keep this collection in the session and I don't want to make another call to the same table for some data as I already have it in collection. Is there any way to reuse the collection for the whole application ?

I am using Struts Hibernate and spring. I want the below list to be used for entire application.

public List searchDocuments() {
List list = new ArrayList();
try {
list =
getHibernateTemplate().find("from Documents");

} catch (DataAccessException e) {
e.printStackTrace();
throw new InfrastructureException(e);
}
return list;
}


Thanks in advance for your suggestions.
