Sorry, I means if you want to use EntityTransaction, you need to have EMF
injected/lookedup.
Do you mean you don't see the data in the table or the table being created?
To get the former, you need transactions to commit the changes, to get the
latter, you need to use provider-specific tools. Do you use GlassFish with
Toplink Essentials? If yes, and you use CLI to deploy your app, you can just
specify --dropandcreatetables=true on the asadmin deploy. Otherwise, you'd need
to set the provider-specific properties in the persistence.xml file.
