The first and probably root issue ... |
2. Putting the SessionFactory in my application: good idea? forum.hibernate.orgWhen setting up my first test Hibernate/Tomcat application, I've noticed that the servlet takes a measurable amount of time (1.5 sec) to read my mapping files and configure itself. I'm thinking I'll put my SessionFactory in the application scope and handle its initalization in my servlet's init() method; is this a good idea or is it a trap? Thanks in advance... ... |

9. How many SessionFactory i can use in one application? forum.hibernate.orgThe SessionFactory and Resource Allocation The SessionFactory itself is a fairly resource intensive object to create.
