    the type field contains int as class Type but it should be Integer at that point.

    Hi Dirk,

    that is because the type in Java and the DB does not match. Surely, because you have defined columns in DB as VARCHAR while in Java are ints.

    Please, put here the code of your Java class and the CREATE TABLE for your table creation. We will try to give a more accurate tip.

    Hi Javier, I got to the bottom of the problem. The Java fields were generated as UpperCamelCase. I switched it to LowerCamelCase and everything now works.

    ex. Private String CustName; changed to Private String custName;
