I have been trying to figure it out for a few days but today I gave up. I got the HTTP Status Error when I try to create Entity Manager Factory.
Full Stack Trace:

So it's a little weird that I get openjpa error when in persistance.xml I've got :
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0">
<persistence-unit name="baza" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>beans.User</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
<property name="javax.persistence.jdbc.user" value="bd2a4c789dfa24" />
<property name="javax.persistence.jdbc.password" value="xxxx" />
<property name="javax.persistence.jdbc.url"

<property name="hibernate.cache.use_second_level_cache" value="false"/>
<property name="hibernate.archive.autodetection" value="true"/>
</properties>
</persistence-unit>
</persistence>
and my Entity class looks like:
package beans;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "user")
public class User {
@Column(name = "iduser")
@Id
private Integer iduser;
@Column(name = "user")
private String user;
@Column(name = "password")
private String password;
@Column(name = "role")
private String role;
public User() {
}
public User(int iduser, String user, String pass, String role) {
this.iduser = iduser;
this.user = user;
this.password = password;
this.role = role;
}
public User(Integer iduser) {
this.iduser = iduser;
}
public Integer getIduser() {
return iduser;
}
public void setIduser(Integer iduser) {
this.iduser = iduser;
}
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
}
So I'm a little bit confused right now. I've been searching for that kind of error but i didn't find a solution for that.
What it could be?
Added:
@Path("user")
public class GetUser
{
@GET
@Produces(MediaType.TEXT_PLAIN)
public List<User> list ()
{
Dao dao = new Dao();
User user = new User();
List<User> userListed = dao.getUser(user);
return userListed;
}
