Answer 1

Can you tell: 1.- The web container/app server you are using?

2.- Where you put your persistence.xml?

Please, show:

1.-Your persistence.xml configuration.

2.-The xml that configures your database driver.

3.-Some dao and it's implementation if you can.

4.-Stack trace, if it's the case.

Answer 2

I'm really curious why you want to involve Errai with the database (via Hibernate ) this much, Errai is a client/server bus , you use it to transport data-back and forth, the db access should be done separately on the server side usually. You need to create a DAO for that which will be called by your server side Errai service implementation.
