Je travaille sur une application web java ee. Tout fonctionnait bien jusqu'à ce que j'utilise JPA dans mon EJB. J'ai cherché toute la journée mais je n'ai pas où. ici est mon EJBjava.lang.NullPointerException lors du déploiement de Java EE sur Glassfish 4.1.1
Stateless(name = "SignupEJB")
public class SignupBean {
@PersistenceContext (unitName = "mypersistenceUnit")
EntityManager em;
UsersEntity user=new UsersEntity();
CountriesEntity countriesName=new CountriesEntity();
public SignupBean() {
}
public List<String> getCountries(){
List<String> countries=new ArrayList<String>();
String[] tmp=new String[9];
int i=0;
for(;i<tmp.length;i++){
tmp[i]=countriesName.getName();
}
countries= Arrays.asList(tmp);
return countries;
}
public void setValues(String fname,String lname, String email, String pass,
String country, String phno, String altmail) {
user.setId(user.getId()+1);
user.setfName(fname);
user.setlName(lname);
user.setEmail(email);
user.setPassme(pass);
user.setCountry(country);
user.setPhNo(phno);
user.setAltMail(altmail);
em.persist(user);
}
}
ici est persistence.xml
