IllegalArgumentException: "Object" is not a known Entity type

So, i'm doing a project in JAVA EE, with JPA (Glassfish Server 4.1.2).
But got this error when I'm doing persist with my Facade :
Caused by: java.lang.IllegalArgumentException: Object: be.isl.prj.story.entity.Universe#3b28b3d6 is not a known Entity type.
And here my files :

Facing java.lang.IllegalArgumentException

I've got this error and not sure why after checking all
java.lang.IllegalArgumentException: Provided id of the wrong type for
class Entities.Person.Person. Expected: class java.lang.Integer, got
class Entities.Person.Person

try {
InitialContext ctx = new InitialContext();

String keyword = request.getParameter("keyword");
List<Person> resList = personBean.searchPerson(keyword);
out.print("<table border='1' width='100%'>"

from here i wanted to perform delete function which lead to deletePeron().

Person person = personBean.getPerson(id);
Person p = new Person();
p.setId(id);
p.setName(person.getName());
p.setDescription(person.getDescription());
personBean.deletePerson(p);
} catch (Exception ex) {
ex.printStackTrace();

Person person = em.find(Person.class, p); must be Person person = em.find(Person.class, p.getId()); in method deletePerson.
because the find method expected the id not the whole object
You can also Change the method to use the id as parameter, because you do not Need more informations to delete the object
#Override
public int deletePerson(int id) {
try {
Person person = em.find(Person.class, id);
em.remove(person);
return 1;
} catch (Exception e) {

On Glassfish server, I am new in using JPA injection: when I try to query the database (retrieve the full list of Company objects), I get the following error:

Thank you for help.

If your post contains the full CompanyDao class, then the following error,
java.lang.NullPointerException
at com.sdzee.dao.CompanyDao.searchCompanies(CompanyDao.java:30)
is because you are using the em variable while you forgot to initialize it.
Query requete = em.createQuery( JPQL_SEARCH_COMPANIES ); // Error --> "em" still null

In the SearchCompanyBean you create your own object of the CompanyDao:
private CompanyDao companyDao = new CompanyDao();
However, in this case field injections won't happen, since the container doesn't know about them (like the PersistenceContext).
So to enable the injection, you have to inject the CompanyDao in the SearchCompanyBean to let the container handle the lifecycle of the object and the dependencies (like you did with the CompanyService).

After each Clean and Build or Compiling of any file I'm getting above exception while accessing any page. To resolve this issue each time I have to restart the glassfish server. Since, this won't be good solution. So, anyone help me to resolve this issue ?

Restart the server then Clean, Build and Deploy your project this how i solved the problem

It seems I resolved my issue. I found this link
And added following code in my class where I'm creating instance of EMF
#PreDestroy
public void destruct()
{
emf.close();
}
and #override servlet destroy method and call above method. Now, It works.!!!

I'm a beginner, and got the same problem. After some days debugging I found out that my problem was the ID field in my MySQL table. It wasn't set as auto-increment. After changing that, problem solved.
Maybe it can be others beginners problem, too.

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'NAME' in 'where clause'

I recently set the Logger Settings better in my Glassfish. Now I have MySQL errors, because I use JPA, I don't know how to fix this errors. All similar questions react with SQL statements and because my JPA I needed a better solution than a SQL query. I need it to use the jdbcrealm security from glassfish
The error that I get:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'NAME' in 'where clause'
Do you need my classes to fix this? or my tables? I can try to supply all info needed.
full stack:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'NAME' in 'where clause'

My User class:
#Entity
#Table(name = "gebruiker")
public class User implements Serializable {
#Id //#Column(name="User_NAME")
private String name;
And this is the bean who adds the users:
#Singleton
#Startup
public class InitBean implements Serializable {
/**
* Creates a new instance of InitBean
*/
#Inject
private UserDAO userDAO;
public InitBean() {
}
#PostConstruct
public void initUsers() {
Role rol1 = new Role("admin");
Role rol2 = new Role("gebruiker");
User u1 = new User("Hans", "http", "geboren 1", "Eindhoven", sha256("Hans"), rol1);
User u2 = new User("Frank", "httpF", "geboren 2", "Best", sha256("Frank"), rol1);
User u3 = new User("Tom", "httpT", "geboren 3", "Geldrop", sha256("Tom"), rol1);
User u4 = new User("Sjaak", "httpS", "geboren 4", "Son", sha256("Sjaak"), rol1);
u1.addFollowing(u2);
u1.addFollowing(u3);
u1.addFollowing(u4);
Tweet t1 = new Tweet("Hallo", new Date(), "PC");
Tweet t2 = new Tweet("Hallo again", new Date(), "PC");
Tweet t3 = new Tweet("Hallo where are you", new Date(), "PC");
u1.addTweet(t1);
u1.addTweet(t2);
u1.addTweet(t3);
rol1.addGebruiker(u1);
rol1.addGebruiker(u2);
rol1.addGebruiker(u3);
rol1.addGebruiker(u4);
userDAO.addRole(rol1);
userDAO.addRole(rol2);
userDAO.create(u1);
userDAO.create(u2);
userDAO.create(u3);
userDAO.create(u4);
}
And this is the userDAO:
public interface UserDAO {
void create(User user);
And this is the userDAOJPA:
#Alternative
#Stateless
public class UserDAOJPA implements UserDAO {
#PersistenceContext(unitName = "KwetterPU")
private EntityManager em;
private List<User> users= new ArrayList();
public UserDAOJPA() {
}
#Override
public void create(User user) {
users.add(user);
em.persist(user);
}
New Stack trace if I change nAME to User_NAME:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'User_NAME' in 'field list'
