The very first error is that you try to create a column called YEAR, but YEAR is a reserved word in Derby. You should select another column name. The second one is that you try to create a column TRIM, also a reserved word. Here also select another column name.

From what I can see the remaining errors are caused by the failure during the creation of the first tables.

It might be easier and less error prone to first create the tables manually and the use your IDE to create the corresponding persistence class (Netbeans makes that very easy, I assume other IDEs have a comparable function).

One more thing: to avoid the automatic creation of 255 character wide varchar columns you can add the desired length in the annotation. There you can also fix the database column name. Example, with a 32 char wide not null column called interiortrim in the db but trim in code:

@Column(name = "INTERIORTRIM", nullable = false, length=32)
private String trim;
