Need Help regarding OpenEJB's error

[Leonardo Carreira]

Hello friends..

i was trying to do practice about OpenEJB which use MySQL as database server..
but i got error..
i am confused for the strange error..

here is my Simple Entity Bean :

@Entity(name="MyTable")
public class MyTable implements Serializable {
private static final long serialVersionUID = -2460310723592952887L;
@Id
private long id;
@Basic
private String nama;
//Getter n setter
}

and here is my persistence.xml :

<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">
<persistence-unit name="test">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<class>com.entities.MyTable</class>
<properties>
<property name="openjpa.ConnectionURL" value="jdbc:mysql://127.0.0.1:3306/MyExample"/>
<property name="openjpa.ConnectionDriverName" value="com.mysql.jdbc.Driver"/>
<property name="openjpa.ConnectionUserName" value="root"/>
<property name="openjpa.ConnectionPassword" value="123456"/>
<property name="openjpa.Log" value="DefaultLevel=WARN, Tool=INFO"/>
</properties>
</persistence-unit>
</persistence>

and here is the message error :
