JDBC table does not exist but it does

Question

I am creating a Java Web with JSF and Facelet that allows an user to register to a database. The issue is that JDBC always tells me that table is not existent. I already lost 5 hours on this and don't know what can be wrong.

It keep saying that the table does not exist, but it does. Would you please be able to help?

Thanks!

Thanks to vanje's comment I could solve the issue. I installed tomcat instead of glassfish and imported the MySQL JDBC that I downloaded from MySQL instead of the one that came with NetBeans. After that it asked for me to actually test the DB connected from the interface, and it worked.
