JPA not committing?

[tommyc7]

I'm not sure if this is the right forum, so sorry if it's not, but here goes....

I am using MyEclipse and am attempting to use the JPA package. I've worked through the tutorial and everything worked fine using Derby. Now, I'm trying to write "real" code against a MySQL DB. Everything is still working fine, except it does not seem to be committing. Do I need to manually write code for that? It seems like if there's a way to do it in Derby there should be a way to do it in MySQL. Is that set up at the database level?

Can anyone shed any light on this?

Thanks!
