Recently I wrote a simple application (EJB3.0), which reads all rows of one unrelated table. 
My problem is that I want to set batch (or fetch - i don't know which term is appropriate) size. As I look at the session trace in oracle 10g, i get, thath it is fetching the data in 10-row packs (73 rows, 8 fetches) . However, during the deployment, I get this message form JBoss:

INFO  [SettingsFactory] JDBC batch size: 15

How can I change that size? It would be great if there is some way to change it for this specific app. I was trying to find out, if there's any way to do this by configuring the persistence.xml, but i couldn't find any docs about it.
