Hi All,

I was running the Annotations Alpha 3 just fine. Then I noticed B1 preview and decided to migrate to it. I did replace the ejb-3.0-edr2.jar and hibernate-annotations.jar

The problem is with scale:

public class Discount implements Serializable {

private Long id;
private double discount;
private Customer owner;


@Column(precision=5, scale=2)
public double getDiscount() {
return discount;
}


I get:
java.lang.NoSuchMethodError: org.hibernate.mapping.Column.setScale()(I)V

at ac.addAnnotatedClass(Discount.class);

When I change the double to say "String", I then get the execption on:
SchemaExport schemaExport = new SchemaExport(ac, props);

I was NOT experiencing any problems with Alpha 3

Hibernate version:

V3.0 & Annotations 3B1 Preview

Mapping documents:

Discount.class which is part of the test package

Code between sessionFactory.openSession() and session.close():

public static void main(String[] args) {
AnnotationConfiguration ac = new AnnotationConfiguration();
ac.setProperty(Environment.HBM2DDL_AUTO, "create-drop");

ac.addAnnotatedClass(Customer.class);
ac.addAnnotatedClass(Discount.class);
ac.addAnnotatedClass(Ticket.class);
ac.addAnnotatedClass(Passport.class);
ac.addPackage("org.hibernate.test.annotations");


Properties props = new Properties();
props.setProperty(Environment.USER, "root");
props.setProperty(Environment.PASS, "password");
props.setProperty(Environment.DIALECT, MySQLDialect.class.getName());
props.setProperty(Environment.URL, "jdbc:mysql://Vin:3306/FA");
props.setProperty(Environment.DRIVER, com.mysql.jdbc.Driver.class
.getName());
props.setProperty(Environment.SHOW_SQL, "true");

SchemaExport schemaExport = new SchemaExport(ac, props);
schemaExport.setOutputFile("c:/xddl.txt");
schemaExport.create(false, true);
}

If this is a problem with B1 Preview, pls. let me know so that I can revert back to Alpha3. Is Alpha3 better to work with for now?

Pls. let me know. This would be great help.

Hi All,

I was hoping for some response on this. Looks like I am alone on this one.

Does this mean that Annotations are still very new to be tried in a NEW real project? As my project is going to be in development for next 6 months, I was really hoping that I use annotations.

I would have ignored the problem had it been just one thing broken. I am just not able to proceed with Annotations B1 because of the above problem. Pls. note that Alpha 3 works just fine.

Any help or suggestions are highly appreciated.

Regards,

Vinay

The stack trace says it all:

This is a show stopper ( at least for me).

How come it works for others? I wonder?
