I'm trying to get data from an H2 database to load up on my JSP pages, and the program just isn't having it. Now, data is being loaded onto the database, its just not coming back out. I try to load a page of book information, and all that comes out is this error:
> Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException: Table "BOOK" not found; SQL statement:
> select book0_.ID as id1_1_, book0_.AUTHOR as author2_1_, book0_.GENRE as genre3_1_, book0_.ILLUSTRATOR as illustra4_1_, book0_.SERIES as series5_1_, book0_.TITLE as title6_1_ from BOOK book0_ [42102-214]
EDIT: As per the project's instructions, we're explicitly not allowed to use JPA.
Here's (what I think is) the relevant code:

Any help at all would be much appreciated.
I've tried various combinations of altered syntax, updated dependencies, and database configurations. An early version of the program without the database worked just fine, and the database is receiving data (basic schema and data SQL files) but I can't seem to get that connection with the client side of things.
