JPA+ Hibernate+ Maven + NetBeans = HTTP Status 500

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.

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"

</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;
}
and structure:

I think you should include mysql driver to your jar dependency(pom.xml).
The error message said: The driver is unknown.

Java JPA Illegal Argument Exception - NamedQuery of name: xyz not found

I am trying to get a user based on their ID using this named query, however I keep getting an illegal argument exception. I've been looking at this code for awhile. Hopefully someone may catch something I might've missed.

Actual error:
Caused by: java.lang.IllegalArgumentException: NamedQuery of name: Myuser.findByUserid not found.
Happens from:
#NamedQuery(name = "Myuser.findByUserid", query = "SELECT m FROM Myuser m WHERE m.userid = :userid"),
UPDATE:
From your persistence.xml:
<persistence-unit name="EJBEntityPU" transaction-type="RESOURCE_LOCAL">
Here you are using transaction-type="RESOURCE_LOCAL". So if you use it, then you are responsible for EntityManager.
Then you must have to follow (JPA Concepts: JPA 101)
You must use the EntityManagerFactory to get an EntityManager
The resulting EntityManager instance is a PersistenceContext/Cache
An EntityManagerFactory can be injected via the #PersistenceUnit
annotation only (not #PersistenceContext)
You are not allowed to use #PersistenceContext to refer to a unit of
type RESOURCE_LOCAL
You must use the EntityTransaction API to begin/commit around every
call to your EntityManger
Calling entityManagerFactory.createEntityManager() twice results in
two separate EntityManager instances and therefor two separate
PersistenceContexts/Caches.
It is almost never a good idea to have more than one instance of an
EntityManager in use (don't create a second one unless you've
destroyed the first)
Solution:
This is an example. you can follow the tutorial if you want to use RESOURCE_LOCAL.

DON'T USE JPA'S RESOURCE_LOCAL ON THE SERVER
Persistence unit as RESOURCE_LOCAL or JTA?
persistence.xml different transaction-type attributes

We got the same error and it was because the entities were missing in persistence.xml

In your persistence.xml is:
<persistence-unit name="EJBEntityPU"
but in your MyuserFacade you use:
#PersistenceContext(unitName = "EJBServer-ejbPU")
You should change that to:
#PersistenceContext(unitName = "EJBEntityPU")

I notice you have class ejbentity.Myuser in your persistence.xml. The class actually lives in a package structure consisting of one directory called "ejbentity"? The stacktrace suggests that your Myuser class with the NamedQuery annotations is not being found, which would be explained if your package structure is not being loaded as you expect.

I don't think that transaction-type has anything to do with #NamedQuery annotation.
This error
Caused by: java.lang.IllegalArgumentException: NamedQuery of name: Myuser.findAll not found.
at org.eclipse.persistence.internal.jpa.QueryImpl.getDatabaseQueryInternal(QueryImpl.java:355)
looks like an EclipseLink bug. Which version are you using ?

I think, that problem is in public LoginLog(Date date, String ip, User user), because when i run the code without User user in LoginLog class, it's normaly working.
Can you help me?
Thank you for your advice.

Provide hibernate mapping for the User object in LoginLog class:
Example:
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "email", nullable = false)
public User getUser() {
