Using MySQL instead of H2 - mysql

Question

When I try to test a simple REST Service, to output the number of users in a web page, it gives a lot of errors. I'm using MySQL and while testing JPA Query in the console, I get the right answer. But when I try from the web page, it gives this errors:

I don't have hibernate.cfg.xml, because i have inserted the data source from the Configuration Menu. How can I change to use MySQL instead of H2?
