How to resolve “Caused by: org.postgresql.util.PSQLException: ERROR: relation “employee” does not exist Position: 13″ error?

I have tried to execute the Hibernate Demo application. I’m getting the below error message.

Source code for Bean class package com.javatpoint;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;


@Entity
public class Employee {
@Id
private int id;
private String firstName,lastName;

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {

}
public void setLastName(String lastName) {
this.lastName = lastName;
}


}

Answer

Hibernate is trying to create entity in hibernatedemo schema. You need to create that schema in database. I did not see your configuration that is pointing to hibernatedemo schema. The cfg.xml is generated by MyEclipse Hibernate tools. Check that configuratioon.

CREATE SCHEMA IF NOT EXISTS schema_name

After creating schema try again to start your application
