I have question concerning mappings in EJB3. I found examples with mappings,
where the values are entity beans. I would like to define a mapping with
primitive types like java.lang.String. My example is the following:
package bean;
import java.io.Serializable;
import java.util.Map;
import javax.persistence.*;
import org.hibernate.annotations.CollectionOfElements;
@Entity
public class Test implements Serializable {
private int id;
private Map<java.lang.String,java.lang.String> texts;
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
public int getId()
{
return id;
}
public void setId(int id)
{
this.id = id;
}
@CollectionOfElements
@MapKey
public Map<java.lang.String,java.lang.String> getTexts()
{
return texts;
}
public void setTexts(Map<java.lang.String,java.lang.String> texts)
{
this.texts = texts;
}
}
and I use jboss-4.0.4RC1 with the "all" configuration. While deploying I
get with the mentioned settings the following errors:
19:17:28,812 WARN [ServiceController] Problem starting service

Please could you tell me how to define a mapping with Strings as values?
Thanks in advance!
