Where are those classess in the annotation package?

I am updating a Spring-Hibernate web application with the Hibernate annotation. For some reason, I run into complains on @Id for can't resolved for a type, @Table(name="comuser") for undefined "name" etc. although I have hibernate-annotations.jar, hibernate-comons-annotations.jar and ejb3-persistence.jar and the Hibernate3 core as mentioned in the document.

What I am missing here?

Hibernate version:
3.3.1 GA

Are you importing the correct classes? There is for example both a @org.hibernate.annotations.Table and a @javax.persistence.Table. Only the @javax.persistence.Table has a "name" attribute.

You can find more information here: http://www.hibernate.org/hib_docs/annot ... ty-hibspec

I use Eclipse with the all hibernate-annotations.jar, hibernate-comons-annotations.jar and hibernate3.jar in the build path. So what you said is that @Id and @Table(name="..") are in the javax.persistence package, but not in Hibernate annotation package.

It's fine that you have the JAR files on the build path, but which classes are you importing in your code? Eg.

Code:

package my.package;
import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name="...")
public class MyClass
{
 ...
}

You also need to include ejb3-persistence.jar to your eclipse build path, so that the right classes (as nordborg said) are imported.

And right, javax.persistence is not part of hibernate-annotations.

Thanks folks.

I thought the annotations were a part of Hibernate one. They are not in fact. I still have a complain on this one:

Code:

@Id(generate=GeneratorType.SEQUENCE, generator="SEQ_USER")

for the generate and generator.

I can work around it with a replacement of

Code:

@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQ_USER")

The last example seems to be identical to the example in the Hibernate docs: http://www.hibernate.org/hib_docs/annot ... identifier

I guess that is how you are supposed to do it. I have never seen the first variant. As far as I know the @Id annotation doesn't support any attributes.
