I know this question has been asked quite a few times over here, but none of the solutions seemed to worked for me. Pardon me for asking this one again as I am new to both maven and hibernate.
hibernate dependency in pom.xml
<hibernate.version>4.2.0.Final</hibernate.version>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>${hibernate.version}</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>${hibernate.version}</version>
</dependency>
This gives me following jars:
hibernate-entitymanager-4.2.0.Final
hibernate-core-4.2.0.Final
hibernate-validator-4.2.0.Final
hibernate-jpa-2.0-api-1.0.1.Final
I also have:
hibernate-commons-annotations-4.0.1.Final
But I am not sure how I got it.
I am using the one-to-one relationship for a Category - Product relationship.
@Entity
@Table(name="Products")
public class Product {
@Id
@Column(name="id")
@GeneratedValue
int productId;
@NotEmpty
@Length(max=50)
@Column(name="name")
String name;
@Column(name="category_id")
int categoryId;
@OneToOne
@ForeignKey(name="categoryId")
private Category category;
// getters and setters
}
Edit:
Since it is clear that Weblogic 11g jpa jar is taking precedence over the 'hibernate-jpa-2.0-api'. Should I fallback to an older version of hibernate that uses jpa-1.0 or is there a way I can enforce weblogic to use 'hibernate-jpa-2.0-api' instead of its jpa jar?
I think the better question to ask is if you have any unneeded jars in your classpath instead of if you have anything missing. Getting a NoSuchMethodError generally means you have one library that needs a particular version of another library and the version it ends up using at runtime is not the right version. In your case, I would look for ejb3-persistence.jar on your classpath as it seems the error has something to do with the OneToOne annotation. Wih hibernate, you should be getting this from hibernate-jpa-2.0-api-1.0.1.Final but my guess is that you also have the OneToOne annotation class file coming from another jar.
Also, it seems as if someone else has already encountered a similar issue. See if this helps:
java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z
Also, since it seems you are using Weblogic 11g which is a JavaEE5 server and not compatible with JavaEE6 which is what the hibernate-jpa-2.0 jar is trying to use. If you are going to deploy to weblogic 11g, you need to find a version of hibernate that is compatible with it and I don't think 4.2.0 Final is.
