Hello,
I try to execute this code:
customer = customerHome.findByPrimaryKey(login);
This code returns this exception:

And the database definition of this table:
create table Customer(
login varchar(16),
name varchar(64),
email varchar(64),
address1 varchar(64),
address2 varchar(64));
alter table Customer
add constraint pk_customer primary key (login);
What am I doing wrong?
Thanks
