I have configured a simple sample dynamic web project in eclipse using openjpa, but I always get a Verfy error. Now I'm at a point that I have no idea anymore. I using TBD plugin for enhancing entity code.
So have you a hint whats worng:
Geronimo Application Server started
20 web99 INFO [DefaultThreadPool 0] openjpa.Runtime - OpenJPA dynamically loaded a validation provider.
21 web99 INFO [DefaultThreadPool 0] openjpa.Runtime - Starting OpenJPA 2.1.1

the persistent.xml
<persistence-unit name="web99" transaction-type="RESOURCE_LOCAL">
<class>model.Hello</class>
<properties>
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/Inventarum"/>
<property name="javax.persistence.jdbc.user" value="root"/>
<property name="javax.persistence.jdbc.password" value="***"/>
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
<property name="openjpa.RuntimeUnenhancedClasses" value="unsupported"/>
</properties>
</persistence-unit>
Here my code:
public class Db {
private EntityManagerFactory factory;
private EntityManager manager;
public Db(){
factory = Persistence.createEntityManagerFactory("web99");
manager = factory.createEntityManager();
}
public String getInfo(){
Query query = manager.createQuery("SELECT i FROM Hello i WHERE i.id=1");
Hello hello = (Hello) query.getSingleResult();
return hello.getName();
}
}
The persistence class generated by eclipse:
@Entity
@Table(name="hello")
public class Hello implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(unique=true, nullable=false)
private int id;
@Column(length=255)
private String name;
public Hello() {
}
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
}
thx
